Astell&Kern PD20 Is the First DAP That Tunes Music to Your Hearing with Audiodo Personal Sound

Published

on

Astell&Kern’s PD20 arrives as the clearest signal yet that the Korean manufacturer still sets the standard in the high end DAP category. For more than a decade, Astell&Kern has defined what a reference portable player should look like, feel like, and most importantly, sound like. With the PD20, the company is not chasing trends. It is extending its lead.

What makes the PD20 different is its integrated Personal Sound system developed with Audiodo, allowing the player to create a listening profile based on the user’s individual hearing characteristics. Personalized audio is not new. Wireless headphones have offered hearing compensation for years. But bringing true left and right ear analysis and correction to a dedicated digital audio player is new territory. Instead of delivering a fixed house sound, the PD20 reshapes the presentation around the listener, raising the bar for what a flagship DAP can do.

Personal Sound System Brings True Hearing Calibration

The PD20 features a Personal Sound system developed in collaboration with Audiodo. The player analyzes the listener’s hearing characteristics and applies independent compensation for the left and right ears, creating a personalized listening profile based on measurable data rather than preset EQ curves.

To enable accurate calibration, Astell&Kern includes dedicated earphones with the PD20 that work in tandem with an integrated hearing test. The process evaluates sensitivity across frequencies and builds a correction profile tailored to the individual user. The result is a sound signature optimized specifically for that listener’s hearing response.

For additional control, the PD20 incorporates a Sound Master Wheel that provides 160 step adjustment from -8.0 dB to +8.0 dB across Bass, Mid, and Treble bands. This allows for precise real time tonal refinement without interrupting playback, giving users both automated personalization and manual tuning flexibility.

Advanced Amplification Architecture 

The PD20 features a Triple AMP architecture with real time switching between three distinct amplification modes Class A, Class A/B, and Hybrid, allowing users to select the presentation that best matches their headphones and listening preferences. Each mode alters bias operation and output behavior to prioritize tonal richness, efficiency, or a balance of both, as outlined in the accompanying image.

astell-kern-pd20-dap-amp-switch
  • Class A Mode: Delivers a rich, high density presentation with minimal distortion, emphasizing tonal weight and a smooth, analog like character.
  • Class A/B Mode: Prioritizes balance and efficiency, offering strong dynamic stability with clean, articulate detail across the frequency range.
  • Hybrid Mode: Blends the tonal refinement of Class A with the efficiency and output capability of Class A/B, aiming for a balanced presentation that combines texture, control, and usable power.

Precision Bias Control for Class A and Hybrid Amplification Modes

A dedicated physical slide switch allows instant mode changes without diving into menus. In Class A and Hybrid modes, users can further adjust amplifier current across three selectable levels to better match headphone load and listening preference.

High: Maximizes output current for greater headroom and dynamic impact. This setting is designed to better control high impedance headphones, delivering a broader soundstage with strong drive and stability.

Mid: Strikes a balance between current output and efficiency, maintaining tonal density while preserving clarity and resolution. It is positioned as the most versatile setting for a wide range of full size headphones.

Low: Reduces output current to lower the noise floor and improve control with high sensitivity earphones. This setting is optimized for IEMs, helping reveal low level detail without introducing unwanted background noise.

Sound Lab Control

The PD20 is conceived as a true sound lab. Built around what Astell&Kern calls Sound Lab Control, the player draws inspiration from professional studio gear in both layout and operation. Dual top mounted wheels separate sound tuning from volume control, while dedicated slide switches manage amplifier mode and current selection. LED lighting provides real time indication of track bit depth and active operating modes, offering clear visual feedback during playback.

DAC: The PD20 is built around the ESS ES9027PRO in a Quad DAC configuration, with four DACs operating independently to reduce inter channel interference and improve signal separation. This architecture is designed to maximize channel balance, resolution, and overall dynamic performance. The PD20 can also function as a USB DAC when connected to a Mac or Windows based PC, extending its use beyond portable playback.

ESA Enhanced Signal Alignment: The PD20 incorporates Astell&Kern’s proprietary ESA technology, which focuses on minimizing group delay by precisely aligning frequency signals across the spectrum. The goal is lower distortion and improved clarity through more accurate time domain performance.

Advanced DAR: Astell&Kern’s second-generation Digital Audio Remaster technology, first introduced on the flagship SP4000, is engineered to produce a more natural and refined presentation. Instead of routing the signal directly to the DAR engine, audio first passes through VSE (Virtual Sound Extender), where missing harmonics are algorithmically reconstructed to enhance tonal completeness. After this stage, DAR processing applies up-sampling for more comprehensive signal refinement. The combined process is designed to improve depth and immersion while preserving the integrity of the original recording.

Atmosphere Technology: The PD20 incorporates Atmosphere processing that expands beyond traditional 2-channel stereo. It creates a virtual 3-dimensional sound field from standard stereo content and offers four selectable presets: Subtle, Balanced, Immersive, and Echoic. Depending on the material and listener preference, users can tailor spatial presentation for music, orchestral works, or audio/video content.

Memory and Networking: The PD20 includes 256GB of internal storage and supports microSD cards up to 2TB. Connectivity features include dual-band 2.4GHz/5GHz Wi-Fi (a/b/g/n/ac), DLNA networking, USB digital-audio output, and USB-C for data transfer and charging.

PCM and DSD: The PD20 supports native playback of high-res PCM music up to 32-bit, 768kHz, and DSD512.

ReplayGain and AK File Drop: Replay Gain keeps playback levels consistent across tracks, while AK File Drop enables seamless, wireless file transfers from devices on the same network with no cables required.

Bluetooth Support: The PD20 incorporates Bluetooth with support for aptX HD, LDAC, and BT Sink mode. BT Sink allows the PD20 to receive audio from an external device over Bluetooth and operate as a Bluetooth DAC. This enables music streamed from a smartphone, tablet, or other source to benefit from the PD20’s internal DAC architecture and amplification stage.

Analog Outputs: The PD20 provides both 3.5mm single ended and 4.4mm balanced headphone outputs, ensuring compatibility with a wide range of headphones, earphones, and in-ear monitors.

Fast Charging: USB PD 3.0 fast-charging support allows the PD20 to reach a full charge in approximately 3.5 hours when used with its included charging cradle and a compatible USB-C power adapter.

Advertisement

Crossfeed: In headphone listening, where left and right channels are fully isolated, long sessions can increase listening fatigue. The PD20’s Crossfeed function blends a controlled portion of each channel into the other with a slight time delay, helping to center the sound image and simulate a more speaker-like presentation. Adjustable parameters include Shelf Cutoff, Shelf Gain, and Mixer Level, allowing users to fine tune the degree of crossfeed to match their listening preferences.

Display: The PD20 features a 6-inch FHD+ display that presents playback status and operational controls with clear visibility and responsive touch interaction.

The Bottom Line 

The Astell&Kern PD20 strengthens the brand’s position at the top of the DAP category by introducing something genuinely new for dedicated players: integrated hearing based personalization. While custom sound profiles have existed in wireless headphones, bringing left and right ear analysis into a Quad DAC, multi mode amplification platform is a first for a reference grade DAP.

Add selectable Class A, Class A/B, and Hybrid amplification, adjustable bias current, second generation DAR processing, and extensive manual tuning, and the PD20 becomes a highly configurable portable source built for serious listening.

astell-kern-pd20-dap-back-front-angles

Priced just under $2000, it undercuts the SP4000 while offering a feature the flagship does not. The PD20 is for experienced headphone users who want reference performance with flexibility and control, and who understand that hearing is not universal. If the idea of a DAP that adapts to you makes sense, the PD20 is one of the most forward thinking players currently available.

For those wondering about the fate of the PD10, the PD20 is not a replacement. The PD10 remains a current model and continues in production alongside the new player.

The key difference between the two centers on DAC architecture. The PD10 is built around dual AKM4191EQ modulators paired with four AKM4498EX DAC chips in a dual DAC configuration, reflecting AKM’s separated digital and analog design philosophy. The PD20, by contrast, adopts four ESS ES9027PRO DACs in a Quad DAC layout, representing a different technical approach within the lineup rather than a generational shift.

Price & Availability

The Astell&Kern PD20 DAP will be available in late March 2026 through Astell & Kern Authorized Dealers, with a suggested retail price of $1,970 (£1799).

Ultion Nuki 2025: one-minute review

The Ultion Nuki 2025 is what happens when a smart lock starts behaving like a complete security product.

At a glance, it’s doing the same job as 2023’s Ultion Nuki Plus: pairing Brisant Secure’s Ultion 3 Star PLUS cylinder and UK-specific door furniture with Nuki’s Smart Lock Pro and platform. In practice, though, this version looks more cohesive, feels quicker to respond and is better aligned with how people actually use a front door every day.

Equinix’s Peter Lantry on powering Ireland sustainably

Published

on

The latest episode of The Leaders’ Room podcast season four features Peter Lantry, managing director of Equinix Ireland. This series is created in partnership with IDA Ireland.

Once again in season four of The Leaders’ Room podcast, we get to know the leaders of some of the most influential multinationals in tech, life sciences and innovation, as well as getting insights into their leadership styles and the high-tech trends they see coming down the line.

In this latest episode, we speak to Peter Lantry, managing director of Equinix Ireland, about the intersection of energy, digital infrastructure and sustainability – and about what Ireland’s digital future could look like if we get the balance right. It’s a wide-ranging and eye-opening conversation about the global data centre giant that sits at the heart of Ireland’s digital ecosystem, and about a man whose career trajectory is decidedly well-matched to the task at hand.

Advertisement

Equinix is the world’s leading co-location retail data centre provider – something Lantry describes, cleverly, as akin to being a “digital airport”, connecting networks, cloud platforms, content providers and enterprises across more than 280 data centres in 35 countries. It works with major players from Nvidia and AWS to Google, as well as with smaller retail clients.

In Ireland, while Equinix has been here 10 years, many of the data centres it now owns, like those of Telecity, have been operating since 1998. The Irish operations have grown significantly since, most recently with the acquisition of two BT data centres and a new Blanchardstown facility, DB7X, now under construction.

What strikes you listening to Lantry is the sheer scale of what Equinix does – more than half a million direct connections between businesses globally, and more than 90pc of all internet traffic in the world flowing through their data centres. The subsea cables that connect Ireland to the rest of the world terminate in Dublin, most of them into an Equinix data centre.

The energy and sustainability conversation is where this episode really catches the imagination. Lantry and his team are doing genuinely pioneering things at Equinix Ireland – hydrogen fuel cells already operating at one of their Dublin sites, solar canopies going in, and an innovative grid solution planned working with the IDA, EirGrid and ESB Networks.

Lantry believes Ireland has a real opportunity, with its ambition to have 22GW of renewable power connecting to the grid by 2030. The question, he says, isn’t whether Ireland can become a leading sustainability hub, but whether we have the collective will to all work together and make it happen.

His vision of data centres that can flex dynamically with the grid – stepping in to support it when needed, rather than adding to its burden – is a compelling one. If we export our data and digital services rather than our electricity, he argues, we could generate perhaps 10 times the value for the Irish economy, so it is crucial, he believes, that we get our digital infrastructure right.

Lantry’s career trajectory means it’s easy to see why Equinix came calling. Starting as a civil and structural engineer with Arup, moving into management science and then consultancy with PwC and IBM, followed by 17 formative years with EirGrid – where he was connecting data centre customers, wind farms and working on the design and implementation of the Irish single electricity market. This was followed by a spell as managing director of Hitachi Energy, where he grew their global data centre business from €350m to €750m in a single year.

It is a CV that makes you understand why his Equinix colleagues remarked, with some amusement, that he was “fairly unique” when the energy crunch hit. He brings something genuinely rare to the role – a deep, practical understanding of both utilities and digital infrastructure, earned over several decades.

On leadership, Lantry talks about Level 5 leadership, referencing James Collins’ book ‘Good to Great’ – leading by example, listening deeply, supporting others and removing the barriers that stop teams from delivering. What comes through clearly is his sense of purpose: the utility-like nature of what Equinix does, connecting everyone and everything in a sustainable way, gives the whole team something genuinely meaningful to rally behind, he says.

I found his emphasis on being fully present in every conversation particularly striking – that good leadership means making the people you are talking with feel truly heard and understood. He describes himself as something of a translator, someone who has spent a career connecting the dots between brilliant people with different expertise and different drivers. Perhaps that instinct was shaped early he says. Lantry grew up moving between countries with his parents – the Netherlands, England, France, Colombia, and back to Ireland – learning to navigate different cultures and ways of engaging. Whatever its roots, it is clearly central to how he leads today.

We’re grateful to all our interviewees again this season, for taking the time out of busy schedules to come into the studio and share their insights and their intelligence with us. And a big thanks as ever to our partners IDA Ireland who make this series possible.

Apple account change alerts abused to send phishing emails

Published

on

Apple logo

Apple account change notifications are being abused to send fake iPhone purchase phishing scams within legitimate emails sent from Apple’s servers, increasing legitimacy and potentially allowing them to bypass spam filters.

A reader shared an email with BleepingComputer that appeared to be a standard Apple security notification that stated their account information had been updated.

However, embedded within the message was a phishing lure claiming that an $899 iPhone purchase had been made via PayPal, along with a phone number to call to cancel the transaction.

Wiz

“Dear User 899 USD iPhone Purchase Via Pay-Pal To Cancel 18023530761,” reads the Apple account phishing email.

“The following changes to your Apple Account, hxfedna24005@icloud.com, were made on April 14, 2026 at 7:01:40 PM GMT:”

“Shipping Information”

These emails are designed to trick recipients into thinking their accounts were used for fraudulent purchases and scare them into calling the scammer’s “support” number.

When calling the number, scammers typically try to convince victims that their accounts have been compromised and may instruct them to install remote access software or provide financial information.

In previous callback phishing campaigns, this remote access has been used to steal funds from bank accounts, deploy malware, or steal data.

Abusing Apple account notifications

While the phishing lure is not new, the campaign illustrates how threat actors continue to evolve their tactics by exploiting legitimate website features to conduct attacks.

The phishing email was sent from Apple’s infrastructure using the address appleid@id.apple.com and passed SPF, DKIM, and DMARC authentication checks, indicating it was a legitimate email from Apple.


dkim=pass header.d=id.apple.com header.i=@id.apple.com header.b=o3ICBLWN
spf=pass (spf.icloud.com: domain of uatdsasadmin@email.apple.com designates 17.111.110.47 as permitted sender) smtp.mailfrom=uatdsasadmin@email.apple.com

Further analysis of the email headers shows that the message originated from Apple mail infrastructure and was not spoofed.


Initial server: rn2-txn-msbadger01107.apple.com
Outbound relay: outbound.mr.icloud.com
IP address: 17.111.110.47 (Apple-owned)

To conduct the attack, the threat actor creates an Apple ID and inserts the phishing message into the account’s personal information fields, splitting the text across the first and last name fields.

BleepingComputer was able to replicate this behavior by creating a test Apple account and adding similar callback phishing language to the first and last name fields. This is because each field cannot contain the entire scam message.

To trigger the Apple account profile change notification, the attacker modifies the account’s shipping information, which causes Apple to send a security alert notifying the user of the change.

Because Apple includes the user-supplied first and last name fields within these notifications, the phishing message is embedded directly into the email and delivered as part of a legitimate alert.

While the target of the attacks received the message, the email was initially sent to an iCloud email address associated with the attacker’s account. This email address is also included in the notification email, making the email look more concerning and potentially leading someone to believe the account was hacked.

Header analysis shows that the original recipient differs from the final delivery address, indicating that the attacker is likely using a mailing list to distribute the emails to multiple targets.

This campaign is similar to a previous phishing campaign that abused iCloud Calendar invites to send fake purchase notifications through Apple’s servers.

Advertisement

As a general rule, users should treat unexpected account alerts claiming purchases or urging them to call support numbers with caution, especially if they did not initiate any recent changes or if they contain unusual email addresses.

BleepingComputer contacted Apple on Friday about this campaign, but did not receive a response, and the abuse is still possible.

Best Meta Glasses (2026): Ray-Ban, Oakley, AR

Published

on

Every time I’ve written about Meta’s AI-enabled glasses, I invariably get asked these questions: Why do you even want these? Why do you want smart glasses that can play music or misidentify native flora in a weirdly cheery voice? I am a lifelong Ray-Ban Wayfarer wearer, and I’m also WIRED’s resident Meta wearer. I grab a pair of Meta glasses whenever I leave the house because I like being able to use one device instead of two or three on a walk. With Meta glasses, I can wear sunglasses and workout headphones in one!

Meta sold more than 7 million pairs in 2025. Take a look at any major outdoor or sporting event, and you’ll see more than a few people wearing these to record snippets for Instagram or TikTok. Meta’s partnership with EssilorLuxottica has made smart glasses accessible, stylish, and useful and is undoubtedly the reason why Google, and now Apple, are trying to horn in on the market. After the notable flop that is the Apple Vision Pro, Apple is recalibrating its face-wearable strategy, moving away from augmented reality (AR) toward simpler, display-less, and hopefully good-looking glasses.

That’s not to say that you shouldn’t be careful how you use these glasses. Meta doesn’t have the greatest track record on privacy, and the company has continued to push forward with policies that are questionable at best. Even if you’re not concerned that face recognition will allow Meta to target immigrants or enable stalkers to find their victims, at the very least, people really do not like the idea that you could start recording them at any moment.

Probably the biggest hurdle to wearing Meta glasses is that even doing so seems like a gross violation of the social contract. After all, these are Mark Zuckerberg’s “pervert glasses.” When I pop these on my head, I’ve had friends (and my spouse) recoil and say, “I have apps to warn me away from people like you.” The best part, though, is that Oakley and Ray-Ban already make really great sunglasses. Even if the battery runs out or you don’t use Meta AI at all, these are stellar at shading your eyes from the sun.

DIY UPS Keeps Home Assistant Running

Published

on

If you put a bunch of computers in charge of your house, it’s generally desirable to ensure their up-time is as close to 100% as possible. An uninterruptible power supply can help in this regard. To that end, that’s why [Bill Collis] whipped one up for his Home Assistant setup.

[Bill]’s UPS is charged with one job—keeping the Home Assistant Green hub and an Xfinity XB7 cable modem online when the grid goes dark. The construction is relatively straightforward. When the grid is up, everything is powered via a Mean Well AC-DC 12 V power supply, while the power is also used to charge a 12.8 V 10 Ah lithium iron phosphate battery pack. When the grid goes out, the system switches over to running the attached hardware on pure battery power. A Victron BatteryProtect is used to automatically disconnect the load if the battery voltage drops too low. Meanwhile, a Shelly Plus Uni module is used to monitor battery voltage and system status, integrated right into Home Assistant itself.

If you want to keep the basics of your smart home going at all times, something like this is a pretty simple way to go.  We’ve featured some other great UPS builds in the past, too. If you’re whipping up your own hardware to keep your home or lab alive in the dark of night, don’t hesitate to notify the tipsline.

NIST to stop rating non-priority flaws due to volume increase

NIST to stop rating non-priority flaws due to volume increase

The National Institute of Standards and Technology will stop assigning severity scores to lower-priority vulnerabilities due to the growing workload from rising submission volumes.

Starting April 15, the service will only analyze and provide additional details (e.g., severity rating, product lists) for security issues that meet specific criteria related to the risk they pose.

The National Vulnerability Database (NVD) will still list all submitted vulnerabilities, but those considered low priority will have a severity rating only from the CVE Numbering Authority (CNA) that evaluated and submitted it.

Wiz

In an announcement this week, the non-regulatory federal agency said it will only provide additional details for vulnerabilities that meet one of the following criteria:

  • are in CISA’s Known Exploited Vulnerabilities (KEV) catalog
  • affect the U.S. federal government software
  • involve critical software as per Executive Order 14028

NIST explained that the decision was driven by the large number of submissions, which grew by 263% recently and continued to accelerate in 2026. The organization enriched 42,000 CVEs in 2025, but it can no longer keep up with the increasing volume.

NIST NVD is a public, centralized database of known software and hardware vulnerabilities, which also provides additional descriptions and analyses on top of the unique identifiers (CVE IDs) assigned by CNAs, such as vendors and the not-for-profit The MITRE Corporation.

Advertisement

The point of enriching vulnerability details is to make CVE entries usable for risk management, including assigning severity scores, identifying affected product versions, classifying weaknesses, and providing links to advisories, patches, or related research.

NIST NVD is used universally by security researchers, software vendors, government agencies, IT professionals, journalists, and regular users seeking more information about a specific security issue.

“All submitted CVEs will still be added to the NVD. However, those that do not meet the criteria above will be categorized as “Not Scheduled,” explains NIST.

“This will allow us to focus on CVEs with the greatest potential for widespread impact. While CVEs that do not meet these criteria may have a significant impact on affected systems, they generally do not present the same level of systemic risk as those in the prioritized categories.”

Advertisement

NIST admits that the new rules allow some potentially high-impact CVE slip through. For this reason, the agency accepts enrichment requests for “any lowest priority CVEs” via email messages at ‘nvd@nist.gov.’

The lack of enrichment or notable delays was noticeable since 2024, but the organization has now formally declared that it will focus on the most important entries.

Building A Rim-Driven Jet Engine

Published

on

Rim-driven thrusters turn the normal propeller-motor arrangement inside out; rather than mounting the motor at the center of the propeller, they use a large hollow motor, with the blades attached to the inside of the rotor. They’re mostly used in ship propellers, though there have been some suggestions to use them in electric aircraft. [Integza], always looking for new and unusual ways to create propulsion, took this idea and made it into a jet engine.

Rather than using an electric motor, the fan in this design is propelled by miniature rocket nozzles along the edge. The fan levitates on a layer of high-pressure gas between the fan rim and the housing. To prevent too much pressurized gas from escaping, the fan and housing needed to fit together closely, but with minimal friction. A prototype made out of acrylic and resin and powered by compressed air proved that the idea worked, but [Integza] wanted to make to this a combustion-powered engine.

The full engine would be similar to a rocket engine, with the fan being the nozzle. The combustion chamber was built out of a brass fitting, and it burned propane in compressed air. The fan and housing were CNC-milled out of aluminium and brass, respectively. They worked well when powered with compressed air, but seized up when connected to the combustion chamber — the fan was thermally expanding and jamming in the housing. Progressively rounding down the edges of the fan failed to solve this, and a hole melted in the fan during one test. [Integza] machined a new fan, which he anodized to increase its heat resistance.

To keep it from overheating, he sprayed water into the combustion chamber, creating steam and cooling the exhaust stream to a manageable temperature. The engine did work, though we do wonder whether the fan actually increases its thrust over that of the base rocket engine.

This isn’t the first unconventional jet engine [Integza]’s built, nor the first which tries to amplify the thrust produced by a rocket engine.

Thanks to [Keith Olson] for the tip!

Panic says the Playdate Catalog won’t accept games made with generative AI

Published

on

Panic, the company behind the tiny and excellent Playdate console, is taking a stand on generative AI. The company has published an AI disclosure that says as of this month, the Playdate Catalog “will no longer accept titles that use ‘Generative AI’ for art, audio, music, text, or dialog.” Panic does allow for developers to use AI assistance for coding, but also says that “we will flag any title as such and specify the extent that it was used (for example, “Lua debugging”) so the customer can decide whether to support it or not.”

This comes a day after Panic announced that Playdate season three was happening and would arrive later this year. For those who don’t recall, the Playdate includes a “season” worth of games when you buy it, 24 titles in total with two revealed every week. Season two came out last year with 12 games — but, as Game Developer notes, one of those games used generative AI for writing and coding. On Bluesky, someone asked Panic if it would disclose what games in season three used AI, and the company confirmed that it was a requirement for season three that developers not use AI for art, music, writing or coding.

Specifically, Panic says you can’t use large language models like ChatGPT or Google Gemini, AI image generators like Stable Diffusion or audio generators like MuseNet and Suno. Previously-approved games with generative AI will be allowed to stay on the catalog with a disclosure that indicates what exactly AI was used for. The company says these guidelines are “under constant discussion and is subject to change at any time.”

I recall seeing AI disclosures on games in the Playdate Catalog in the past, but it makes sense to be up-front and clear on exactly what Panic allows and what it will reject. That said, it’s fairly easy to sideload games onto a Playdate, so anyone who wants to use generative AI to make a game isn’t entirely out of luck — though distribution and discovery for Playdate owners will obviously be harder.

Meanwhile, there’s an interesting Steam event taking place soon. InterfaceX26 will run from April 27 until May 4. This one is focused on games that deal with made-up operating systems and other custom interfaces. Organizers have brought together more than 150 developers and publishers, who are asking Valve to introduce an official “Fake OS” tag for games on Steam.

Some neat games will be included in a sale and a showcase on May 2, including Blippo+, TR-49 and The Roottrees are Dead. Expect demos and relevant new releases too. Speaking of which…

New releases

We’ve been waiting a very long time for Replaced. This cyberpunk adventure from Sad Cat Studios and publisher Thunderful finally landed this week on Steam, GOG, Xbox on PC and Xbox Series X/S. It’s on Game Pass Ultimate and PC Game Pass. Otherwise, the base game costs $20. A supporter edition that includes the soundtrack is $25. It’ll hit the Epic Games Store at a later date.

The game was initially supposed to arrive in 2022. It certainly didn’t help that Sad Cat Studios was forced to relocate from Belarus to Cyprus after Russia’s invasion of Ukraine. But the game is finally here and it debuted to generally positive reviews.

Replaced is a 2.5D action platformer set in an alternate version of 1980s America, in which you play as an AI trapped in a human body that may or may not dream of electric sheep. I haven’t yet had a chance to properly jump into this gorgeous-looking game, but I’m hoping to do so this weekend.

Speaking of games I’ve long had on my wishlist, Gecko Gods arrived this week. I think I first clapped eyes on this around 2022. Various trailers charmed me with the idea of a puzzle exploration platformer that casts you in the role of a gecko that’s able to run along walls and ceilings.

I’ve played around 90 minutes of this one so far. I dig the look and the gecko is very cute (being able to customize its appearance is a nice touch). I love that you “collect” different types of bugs by eating them. It’s a fairly relaxing game, which is broadly what I need at the minute.

I think there are some issues here, though. I’ve explored two of the main five islands in the open world and it feels a bit sparse so far. The joy of being able to clamber up and around any object complicates things when it comes to more precise platforming sections. While the sailing sections are pretty, the boat is clunky to control on the choppy water. I ran into some mild technical issues as well on PS5 with occasional framerate dips and objects popping in. Hopefully, that’s something the developers at Inresin are able to address.

Gecko Gods — from publishers Super Rare Originals and Gamersky Games — is available now on Steam, PS5 and Nintendo Switch. It’s normally $20, but there’s a 10 percent launch discount until April 30 (on PS5, this only applies to PlayStation Plus members)

Another highly anticipated game landed this week in the form of Mouse: PI for Hire. We’ve had our eyes on this first-person shooter/detective game with sumptuous rubberhose-style animation for quite some time. Reviews have been generally positive so far, and it seems that there’s enough substance here to live up to those stellar visuals.

Mouse: PI for Hire — from Fumi Games and publisher PlaySide — is out now for $30. It’s available on PC, Nintendo Switch 2, PS5 and Xbox Series X/S.

Thirsty Suitors developer Outerloop Games and co-publisher Outersloth served up the cooking-themed Dosa Divas this week. It tells the story of two sisters who set out on a journey with their mech to take down a fast food empire and reconnect communities through cooking.

It caught my eye when I saw it during a showcase a while back and it has a great concept, though I don’t exactly love turn-based combat. I’ve read a few lukewarm reviews of the game, and the consensus seems to be that the cooking mechanics and combat perhaps needed some more time to simmer.

If you’d like to try Dosa Divas yourself, you can pick it up on Steam, Xbox Series X/S, PS5, Nintendo Switch and Switch 2. It’ll usually run you $20, but there’s a 10 percent launch discount until April 28.

If you’re looking for a puzzle game that can be relaxing or rather dark, depending on your mood, it might be worth checking out A Storied Life: Tabitha. As you pack up the home of a late loved one, you’ll need to decide which items to keep in the limited storage space you have and discard the rest. You’ll need to wrap fragile items in bubble wrap and vacuum pack soft items to save room in the boxes.

As you save items, you’ll unlock words that you can use to fill in the blanks of your loved one’s life and tell their story, Mad Libs-style. Given that you’ll find items like a blackmail letter and a shirt with lipstick on the collar, it seems like there’s a lot of variety to the kinds of stories you can tell.

A Storied Life: Tabitha is available on Steam now. It’ll normally run you $15, but you can save 10 percent if you buy it before April 28.

To round out this section, I’ll quickly note that Hades 2 is out now on PS5 and Xbox Series X/S for  $30, with a 20 percent launch discount. It’s on Game Pass Ultimate, Game Pass Premium and PC Game Pass too.

I bought Hades 2 when Supergiant Games brought it to Steam early access two years ago, telling myself I’d wait until the full game was out. But I still haven’t gotten around to it yet. There are always too many games tugging at my fragile attention span and Hades 2 faded into the background for me. I really ought to play it, I know!

Upcoming

I’m keeping an eye out for Agefield High: Rock the School from Refugium Games. This spiritual successor to Rockstar’s Bully is set to arrive this summer on Steam. It emerged this week that it will hit PS5 and Xbox Series X/S later in the year.

It’s a coming-of-age adventure in which you play as Sam, a young lad who has moved to a new school in the early 2000s. He wants to make his last few months of high school a time to remember.

There’s a branching narrative with multiple endings here — you can opt to go to classes and be a good student, or skip school and cause trouble. As a mostly rule-abiding student way back when, I’d be tempted to go for the latter. This seems like a bit of a life sim with a broad array of activities and ways to get into bother. I’m looking forward to it.

The latest edition of the Galaxies Showcase — yet another indie spotlight event — took place this week and The Backworld caught my attention. This is a Mother-inspired RPG from Numor Games and publisher Top Hat with charming art direction (yes, I did see that one character doing a Naruto run), an intriguing mix of characters and…

Oh no, why did the music stop? Why did it get so dark all of a sudden? What are these horrifying beasts that are chasing my character? Yup, there’s a heavy horror element here. Numor took inspiration from The Backrooms as well.

The Backworld will be released later this year. A demo just hit Steam.

A Study in Blue, from Relate Games, was another highlight of the Galaxies Showcase, thanks in large part to that impressive animation. This is a point-and-click adventure in which you play as two characters with complex pasts: private detective Kenneth and runaway Blue.

You’ll explore a semi-open world and solve crimes by collecting clues and calling out characters’ lies. There are three intertwined story acts and multiple endings. A Steam demo featuring a side quest from the main game that’ll take around two hours to complete is available now.

I’m always going to be interested in any game that riffs on The Legend of Zelda: A Link to the Past. On the face of this trailer, Elementallis developer AnKae Games seems to borrow quite a bit of the design language and other ideas from the SNES classic. Still, if you’re going to crib from anything, it may as well be the best game of all time.

This 2D action RPG, which is also published by Top Hat and has a heavier focus on elemental powers than A Link to the Past, looks very much like my kind of jam. It’s coming to Steam, GOG, Switch, PS4, PS5, Xbox Series X/S and Xbox One on April 28. Per the eShop listing, it’ll cost $18.
