Awesome Games Done Quick (AGDQ) 2024 has wrapped after a nonstop weeklong speedrunning marathon. This year’s charity raised over $2.5 million for the Prevent Cancer Foundation. Other highlights included four broken world records and a dog named Peanut Butter beating the oddball NES classic Gyromite.

This year’s AGDQ, which took place in Pittsburgh, passed the million-dollar threshold early on day five. Standout playthroughs included a no-hit run of Resident Evil 2 (2019), Super Mario 64 finished entirely on an electric drum kit (in 23 minutes!), and a blindfolded four-player / one-controller run of The Legend of Zelda: Majora’s Mask.

World records broken in this year’s event included speed runner Glitchcat7 finishing the insanely difficult Super Mario World mod Luminescent in 41 minutes, 36 seconds. Talia finished the Celeste mod Strawberry Jam Collab in 49 minutes, 13 seconds. Mechalink beat the Sega Saturn game Virtual Hydlide in 27 minutes and 11 seconds. Finally, Bobbeigh conquered the Castlevania spiritual successor Bloodstained: Ritual of the Night — on hard mode — in 30 minutes and 24 seconds.

Peanut Butter the Shiba Inu is now etched into the annals of GDQ history as the first canine-assisted speed run at one of the charity events. The well-trained pooch helped his owner (JSR_) finish the 1985 NES game Gyromite in 26 minutes and 24 seconds. He responded to well-timed commands, pressing his paws on a floor-pedal-operated controller to move the game’s red and green pipes up and down to lead Professor Hector to safety. (He was compensated with ham and cheese for his work.) You can watch Peanut Butter’s memorable run below.

This year’s AGDQ pushes the Games Done Quick fundraising total, stretching back 14 years, to more than $48.9 million. In addition to the Prevent Cancer Foundation, the showcases have raised money for organizations like Doctors Without Borders, Malala Fund, Organization for Autism Research and CARE. The next marathon will be an all-women speedrunning event called Frost Fatales, held online from March 3 to 10, with proceeds benefitting the National Women’s Law Center.

A Call of Duty game sells. That’s what it does. And it usually tops the sales charts each year. Pretty much every year since 2009. Activision’s warfare simulations (we can just call them first-person shooters, right?) have mostly done just that. Last year’s a bit different: Call of Duty: Modern Warfare III landed in second place.

To convey the gravitational pull of CoD, when Microsoft was fighting to buy Activision Blizzard – makers of the game series — the Xbox maker had to make concessions and ensure the games would come to PlayStation and other platforms to make the purchase happen.

This time around, however, Hogwarts Legacy — a game not without its own controversies — beat it to the top spot. It did benefit from being the only Harry Potter game in a decade. In that time, there have been 11 Call of Duty releases. Headlines aside, the series will be fine. Another thing worth noting: 2022’s Call of Duty: Modern Warfare II still took the number seven spot.

Instagram will start telling night owl teens to close the app and go to sleep

Younger users won’t be able to turn off the Nighttime Nudges.

Instagram’s latest mindfulness feature targets teens. When a younger user scrolls for more than 10 minutes in Reels or their DMs, the app will suggest they close the app and get to bed. Nighttime Nudges will automatically appear on teen accounts, and it won’t be possible to switch them off. Instagram didn’t specify whether the feature will be for all teenagers or just under 18s.

Could we get it for us over 18s too?

Apple’s Vision Pro won’t have access to YouTube and Spotify apps at launch

Users will have to access them from a browser.

Engadget

According to Bloomberg, Google’s YouTube and Spotify don’t have any plans to develop an application for Apple’s Vision Pro, at the moment. YouTube won’t make its iPad app available for download on the headset, either. For these apps — including Netflix — users will have to watch things through the web browser. In most cases, this will mean losing the ability to watch or listen to content offline. According to MacStories, Meta’s Instagram and Facebook might also be missing from the Vision Pro’s app store. Companies might be waiting to see whether it’s worth dedicating resources for the $3,500 headset — the Apple Watch took time to generate its own app library.

Rock Band 4’s weekly DLC drops are coming to an end. Harmonix said Wednesday the upcoming batch of new songs on January 25 will be the game’s last. Although all other live services will remain active, the developer plans to give full attention to the Rock Band-like Fortnite Festival, a rhythm game inside Epic’s digital world.

Product manager Daniel Sussman waxed nostalgic about Rock Band 4’s impressive eight-year run of new song drops each week. “Taking a longer look back, I see the Rock Band DLC catalog as a huge achievement in persistence and commitment — over the years we’ve cleared, authored and released nearly 3,000 songs as DLC and well over 3,000 if you include all the game soundtracks,” he wrote in an announcement blog post. “That’s wild.”

Sussman says Harmonix is committed to protecting its licensing, promising that purchased content will remain available. He adds that all the game’s other live services, including Rivals and online play, will continue as usual. There just won’t be any more new music for the rhythm game, which arrived in 2015 with 65 tracks.

Epic Games

Fortnite Festival, launched in December, is a rock god stage in the popular battle royale title. It has the advantage of being free: You don’t have to pay a couple of bucks to fulfill your dreams of jamming out to “Seven Nation Army,” The Cranberries’ “Zombie” or Bel Biv Devoe’s “Poison.”

Rock Band 4 instrument support is on its way to Epic’s virtual stage. “If you are a fan of the rhythm game category, Fortnite Festival is the place to be; and with support for RB4 instruments coming, this is not the time to hang up your guitars just yet…”

Harmonix is tight-lipped about its final tracks, but it promises thematic relevance. “We deliberated long and hard about how to frame the last blast of RB DLC of this era,” Sussman explained. “The last two weeks will feature some tear jerkers that sum up our feelings about this moment. We thank you for your commitment to and passion for this wonderful game.”

Activision has taken aim at Call of Duty cheaters in a swathe of novel and often hilarious ways over the last few years, from cutting their parachutes so they splat onto the ground in Warzone to straight up taking their guns away. The latest tactic targets those who use illicit tools to activate aim assist while playing with a mouse and keyboard.

The Ricochet anti-cheat team says that when its security detection systems spot such players, the Call of Duty app will simply close itself. No clever trick like cloning another real player from elsewhere in the match. The game will just shut down. "Repeated use of these tools may lead to further account action," the Ricochet group wrote on X. In other words, Activision will likely suspend or permanently ban persistent offenders.

As always, the idea behind this tactic is to level the playing field for everyone. Aim assist is a feature primarily designed for console or controller players to make up for the greater accuracy afforded by a mouse. While this most recent effort to frustrate bad actors won't solve all of Call of Duty's cheating problems (wallhacks still seem to be an issue), annoying cheaters into perhaps changing their habits continues to be a very funny strategy on Activision's part.

Instagram has revealed its latest mindfulness feature targeted at teens. When a younger user scrolls for more than 10 minutes in the likes of Reels or their direct messages, the app will suggest that they close the app and get to bed.

These "Nighttime Nudges" will automatically appear on teens' accounts and it won't be possible to switch them off. Instagram didn't specify whether the feature will be enabled for all teenagers or only under-18s. 

The idea, according to Instagram, is to give teens who aren't already using features such as Take a Break reminders to close the app for the night. "We want teens to leave Instagram feeling like the time they spend on the app is meaningful and intentional, and we know sleep is particularly important for young people," Instagram said.

The new tool follows other features Instagram has rolled out to help teens and their parents manage time spent on the app. Along with Take a Break and parental supervision features, this includes the likes of Quiet Mode. The latter enables teens to mute notifications, automatically reply to messages and let their friends and followers know that they're unavailable and doing something else, such as studying or sleeping.

Sony and developer Naughty Dog got an earful back in 2022 when they announced The Last of Us Part I, a ground-up PS5 remake of the 2013 title that was originally released on the PS3 (and then remastered a year later for the just-launched PS4). Most of that came down to the $70 price tag. Yes, the game looked incredible, there were some new modes added for super-fans and enemy AI had been upgraded, but the level design and gameplay were identical to the original. Plenty of people fairly called it a money grab.

The good news that The Last of Us Part II Remastered, announced back in November, escapes that tag for two important reasons. One, it’s a $10 upgrade for people who bought the PS4 versions (or $50 outright). Two, there’s a new roguelike game mode called No Return which is easily worth that upgrade price on its own.

Before diving into No Return, though, here’s a high-level overview of what we’re dealing with. The Last of Us Part II Remastered is, as the title suggests, an upgraded version of the 2020 PS4 release. I reviewed that game when it first launched — and nearly everything I said in 2020 still applies here, because the story and gameplay are unchanged.

Sony / Naughty Dog

But, as with any good remaster, the new version looks better than the already-impressive PS4 version. Part II Remastered can run in fidelity or performance modes. The former outputs at 4K and targets 30 fps, while the latter targets 60 fps and renders at 1440p (with output at upscaled 4K or 1440p, depending on your console settings). There’s also an “unlocked framerate” feature for TVs that support variable refresh rates.

I typically opt for performance mode. The difference resolution makes is usually minimal to my eyes, and that’s the case here as well. I’d much rather have the fluidity and precision that comes with a higher frame rate. But fidelity settings with an unlocked frame rate definitely hits above 30 and is a pretty great balance for those with VRR TVs — though if you’re on the ultra-difficult Grounded mode or attempting a permadeath runthrough, you’ll probably want to go straight to the performance setting.

Either way, the game looks stunning, but not wildly different from how the original Part II looked on the PS5. Things are sharper and more vivid across the board, as you’d expect. And the high frame rates in performance mode are great, though it’s worth noting that the original version of Part II can also hit 60 fps when played on a PS5.

Other niceties beyond the visuals include full support for the DualSense controller, including excellent use of haptics throughout. The game’s very first cut scene shows Part I protagonist Joel cleaning the frets on a guitar, and you can feel slight vibrations from left to right as his hand moves across the guitar neck.

There’s also full support for the DualSense adaptive triggers, so you feel different resistance and feedback depending on which weapon you’re using. As in most games, DualSense features aren’t the kind of thing that’ll be in the forefront of your mind as you play, but there’s no question they add a nice level of extra immersion to the experience.

The Last of Us Part II Remastered isn’t just a visual upgrade, though — there’s a bunch of new content. Most significant is No Return, an addictive combat experience which I have poured a ridiculous amount of time into already. The high-level overview for No Return is that it’s a series of randomized encounters with the four main enemy factions in the game: the WLF, Seraphites, Rattlers and, of course, the Infected.

In some encounters, you need to clear three waves of enemies; in others you’re hunted by unending hordes until the timer runs out. There’s also one where you’re challenged to capture a safe from a wave of enemies in limited time, and another where you have to defend an ally against a large swarm of Infected that keep coming. After five levels, you’ll hit a “boss.” There are six total boss levels that you progressively unlock by finishing a run without dying. But if you die at any stage of the run, you’re sent back to the beginning.

In between each encounter, you can craft upgrades for your weapons and buy new gear from the trading post to help you survive the progressively more difficult stages. And there are a ton of different modifications that affect how each level plays out. For example, you might randomly get a mod that gives you health when you land a melee attack, or you might end up with one where Infected enemies are invisible, just shadows in your flashlight. Sometimes, the level might be reversed, crafting an item will give you parts to upgrade a weapon or a dark noir filter will be applied. These mods aren’t on every level, and only two will show up at a time, so it doesn’t feel like there’s too much madness across a run. But, they can definitely shake up what might otherwise be a familiar stage.

Sony / Naughty Dog

I’m just scratching the surface on how much you can customize this experience. There are a total of 10 unlockable characters you can play as from both the Jackson crew (Ellie, Dina, Jesse, Tommy and Joel) and those you meet in Seattle (Abby, Lev, Yara, Manny and Mel). Each has different traits (Ellie gets more supplements, Joel can’t dodge but is more resistant to melee attacks, Lev is focused on stealth, etc.). Between different characters, the different signature weapons they have and all the different weapons and player upgrades you can get through the run, every No Return experience will be wildly different.

There are a ton of details to talk about in No Return, but suffice it to say it’s extremely addictive and easily worth the $10 upgrade. If they just added this mode to the PS4 version of The Last of Us Part II, I would still have no qualms about recommending fans buy it. I’ve seen hosts of extremely impressive combat videos from Part II since the game was released, and I’m sure we’re about to get another wave as people show off their narrow escapes and dominant destruction of hordes of Infect in No Return. It’s a ton of fun — though I will admit that the extremely violent tone requires extended breaks from time to time to get out of the murderous mindset it requires.

Sony / Naughty Dog

No Return is the biggest addition to the game by far, but there is more new content for the hardcore fans. All of the main game’s main cinematics now have optional audio commentary from director Neil Druckmann, writer Hailey Gross and actors Troy Baker, Ashley Johnson and Laura Bailey. The Last of Us Part II has a sprawling, complicated and sometimes controversial storyline, and hearing behind-the-scenes chatter about how it all came together is a great way to dig further into the game’s creation.

Similarly, Naughty Dog included three “lost levels” that are quite rough but show off some ideas that flesh out the world and Ellie’s character a bit, complete with audio commentary from developers on what they were shooting for and why they were ultimately abandoned. My favorite is one that takes place in Jackson before a pivotal scene between Ellie and Dina. In this, Ellie wanders around a festival, having a few drinks, talking with other characters, playing around with kids in the town and trying out some carnival games. The setting repurposes the game’s mechanics, which are usually used for enacting violence, and instead puts them in a totally different light.

These levels are far from finished — the aforementioned Jackson scene doesn’t have any dialog at all, only subtitles. And the textures, facial expressions and mechanics all definitely feel rough. They’re also pretty quick experiences, probably lasting between five and 10 minutes. A treat only for hardcore fans, but still a treat.

Sony / Naughty Dog

Rounding out the package are a bunch of new unlockable character skins, including an adorable one of Ellie in an astronaut suit, complete with a helmet. The already-extensive Photo Mode has gotten a few upgrades, like lights you can place around a scene to enhance the drama. And there’s a goofy but fun “guitar free play” mode, where you can experiment with an enhanced version of the interludes in the game where you strum a guitar to kick off key story beats. Plenty of enterprising players have already made some pretty wild creations using the in-game guitar, and now you can switch between multiple guitar types (acoustic, nylon-string, banjo) and add effects that really open up the creative possibilities.

Sony / Naughty Dog

If you’re someone interested in The Last of Us and haven’t played Part II yet, this is the obvious best way to do so. I still highly recommend the game — it’s an intense, exhausting journey that puts some characters I love through the wringer, but it’s an undeniably epic adventure. It’s not “fun” in the traditional sense, but it is compelling. As I wrote in 2020, so much stands out: moments of extreme tension, moments that made me yell in shock or surprise, thought-provoking drama and even unexpected joy amidst the bleak reality of Ellie and Abby's dual journeys.

But if you’ve played the original, is this remaster worth picking up? If you’re a fan of the series, the $10 upgrade is unquestionably worth it. No Return is worth the price of admission on its own, and all the graphical upgrades, controller improvements and bonus content are things you’ll appreciate. Like I said when I reviewed The Last of Us Part I — if you’re the kind of person who will pick up this game and play it to experience the story every year or two, like I do, this is the best way to do it.

We’re getting closer and closer to launch day for Apple’s Vision Pro headset, which means if you’re not yet sold on ordering one, you’ll soon be able to try it out in the store. But don’t expect the process to be quick and easy. In the Power On newsletter this week, Bloomberg’s Mark Gurman says customers hoping for a demo will each have to go through face scans and the subsequent assembly of a custom Vision Pro, a walkthrough of the interface and all the controls, and device calibration — all before a 25-minute demonstration of the Vision Pro experience.

The Vision Pro is meant to sit just right on its wearer’s face, with multiple sizing options for the light seal, foam cushion and band. And Apple isn’t planning on taking the risk of an attempted universal fit for in-store demos, according to Gurman. In addition to face scans, employees will have a device to scan customers’ glasses to determine the right prescription for Vision Pro lenses. Each store “will have hundreds of lenses on hand for demos,” Gurman says, and employees will tag-team the process, with one on the floor taking customers’ details and another in the back handling assembly.

Some stores will have at least a dozen Vision Pro headsets around for people to try. During the actual demo, according to Gurman, users will be shown a series of normal, panorama and “spatial” photos, spatial videos, immersive experiences including a “scene that makes users feel as if they’re on a tightrope,” and a glimpse at what it will be like using the Vision Pro as a computer. Signups will start at 8AM local time on February 2.

If you’re just walking in to buy a Vision Pro, the process should be much simpler. You’ll have to go through the face scans — as will anyone ordering one online — and then all the correct pieces will be boxed up for you right there, Gurman says. There will also be multiple display-only units in each store, if you just want to take a look.

The Environmental Protection Agency has scrapped a plan to phase out mammal testing for studying chemical toxicity, Science reports. In 2019, the regulatory agency vowed to completely phase out animal testing for toxicology studies by 2035 in favor of non-animal “test subjects” programmed into computer models.

The call to challenge the status quo was controversial from the start — it not only was going to impact thousands of studies and experiments, but many scientists argued that computer models were nowhere near ready to replace animals as test subjects. In a letter written by a group of public health officials, the experts urged the EPA’s head Michael Regan to reconsider the ban because computational models, in their opinion, were “not yet developed to the point” where they could be relied on for risk assessments.

In order for the new ban to have taken effect, the EPA said there needed to be “scientific confidence” that non-animal models could soundly replace critters like mice and rabbits in labs. Despite the 2035 deadline being put on ice, however, an EPA spokesperson told Science that it would still explore alternatives to animal testing.

The ambitious plan is not entirely a lost cause, though. While the EPA hasn’t made any official statements about how it plans to work toward its original goal, now without a deadline, some studies have shown promise that computational models might effectively reflect the toxicology of certain chemicals during testing. In some instances, these studies suggest, they can even outperform lab rats.

3D developments like technical organoids are also popping up on the research front by way of stem cells that allow duped livers to be tested and evaluated during research as a human liver would. Labs are currently working on ways to more effectively develop realistic organs using 3D printers. But it might be a while before 3D printing can consistently be used to assist biologists and pharmacologists for research and drug testing.

I’ve been interested in solar generators for a long while, but very few of them ever felt worthy of specific comment. Many of them historically boasted of running laptops, TVs or coolers, but their constrained outputs made them incapable of powering kettles, washing machines or air conditioners. CES 2024 has shown that the industry has moved beyond those limitations, with newer units capable of fulfilling the promise inherent in their names.

Take the new EcoFlow Delta Pro Ultra, the company’s flagship whole-home backup, which can pump out 7,200W. The company claims the unit is strong enough to power a three ton central air unit, one of the most demanding appliances in the home. Plus, because it’s a modular design, you can add up to three of these units to the same home for a cumulative output of 21.6kW — and, with enough batteries, a total storage capacity of 90kWh.

Solix, Anker’s big battery division, was here at CES showing off its new F3800 portable power station. The company moved into the home battery market in the summer of 2023 but even something designed to be wheeled around is shorn of the older limitations. The F3800 can pump out a peak of 6,000W – a figure you can double if you buy two – enough to add juice to an EV in a pinch. And, best of all, it’s currently available to buy for $3,499 which, depending on how much solar you pair it with, should mean payback considerations are less than five years.

Jackery, which has been a name in this market for a long while, will sell you its 2000 Plus, complete with two 200W solar panels, for just $3,300. That small unit, if you use the right accessory, can be wired into your home’s breaker box and similarly has a surge peak of 6,000W. It’s not quite as muscular as some of its competitors, but the low cost means that it’s hard to argue against if you’re looking to dip a toe into this world.

Cost for solar panels and batteries have fallen dramatically in the last few years, with Our World in Data reporting that the cost of a panel has dropped from $2.32 per watt in 2010 to just $0.26 per watt in 2022. BloombergNEF reported that lithium ion battery prices have fallen from $780 per kWh in 2013 down to $139 per kWh in 2023. And it’s this that has enabled this surge in home battery uptake.

Emma Ross, who heads up communications for Jackery, says that customers are drawn to these falling prices. She added that, second to cost, the plug-and-play element of the gear is key, offering “the perfect combination of convenience and environmental friendliness.” The low cost and ease of installation means these systems “require less investment than other, larger solar options,” making it a “less intimidating” way for wary neophytes to get involved.

Nick Bowers, head of business development at EcoFlow in the US, says that consumers are frustrated with the domestic energy market. He claims rate increases, natural disasters, power outages and climate change have all driven people toward buying solar gear. “The pain points pushing people toward renewables,” he said, “will only grow more acute,” with users looking to “be less reliant on the grid.”

And the solar industry writ large is gearing up to address a surge in demand expected to come as these prices fall. Eric Villines, head of global communications at Anker, says that the only roadblock right now is the fact most homeowners aren’t investing in storage alongside their solar gear. “In 2022, only ten percent of installed home solar systems in the US included energy storage,” he told Engadget, “preventing homeowners from securing protection against blackouts.” To address this, the company surveyed users and found most were either put off by the high price, or didn’t even know that it was a viable option for them.

Which is why the knock-down prices on hardware the likes of which we’ve seen at CES 2024 is hopefully going to address some of those issues. After all, whereas some of this gear would have cost tens of thousands of dollars a few years ago, they’re now less than half that price. Perhaps these units will serve as a gateway drug to investments into more expansive whole home batteries further down the line. And that’s a good first step towards our bigger, and hopefully brighter solar future.

We're reporting live from CES 2024 in Las Vegas from January 6-12. Keep up with all the latest news from the show here.

While MEMS drivers may be the next big thing in true wireless earbuds, the first models with the solid-state components still require a hybrid setup. These products pair a MEMS speaker with a dynamic driver to ensure proper bass performance. The current-gen driver from xMEMS, a California-based company that develops the audio components, is called Cowell and it's already available in earbuds from the likes of Creative and Noble Audio. 

The next-gen MEMS driver is called Cypress, and while it won't arrive in new products until 2025, I got a chance to hear the difference been it and Cowell at CES 2024 here in Las Vegas — and it's quite striking. With Cowell, there's bass, but it's subdued and the emphasis is on the highs and the mids. It sounds great, on both complete products and reference designs, offering punchy highs, full mids and great clarity. With Cypress alone though, there's a blanket of warm, bassy low-end that really fills out the soundstage. It will be a massive improvement for what MEMS drivers are capable of doing for wireless earbuds. 

"We moved to a sound from ultrasound principle where we have ultrasonic modulation and demodulation to deliver 30 to 40 times greater low-frequency pressure for anti-noise generation for ANC earbuds, while still delivering all of the benefits of our solid state speakers," xMEMS vice president of marketing Mike Housholder explained. "Wide dynamic range, with excellent low-frequency performance for deep bass and noise cancellation."

Indeed, that 30 to 40 times louder bass response was clearly evident when on a Cypress reference design. The prototype was built to showcase the MEMS drivers on their own, without that secondary dynamic driver today's true wireless models require for bass. The results are the pristine clarity you'd expect in a send of high-end wireless headphones or even some audiophile-grade cans. The additional bass isn't loud and boomy, but instead it's warm and full, inviting you to stay and listen a while. And that I did: I had a hard time putting the Cypress prototype down even when I felt I'd overstayed my welcome. 

On the whole, MEMS drivers offer a host of benefits over coil speakers that should all lead to better audio quality in your earbuds. They're more efficient in terms of mechanical response, with faster speeds there contributing to increased detail and clarity — something I certainly noticed on the Noble Audio FoKus Triumph wireless earbuds. This model pairs Cowell with a 6.5mm dynamic driver, but the boost in fidelity in the mids and highs is apparent. And getting a set of earbuds with MEMS drivers doesn't mean you'll pay more. The two models Creative has already debuted are $130 and $150. The same will be true for upcoming products with the ultrasonic Cypress drivers, according to Housholder. 

"We see ourselves going to market first in flagship products," he said. "As with our current products, we really see the sweet spot for our products anywhere 150 and up, [which] is easily achievable day one. And then over time and over volume, getting down to that $100 price point."

And that's really the big takeaway from me. For years, companies have offered true wireless earbuds with some of the features of more premium flagship models, but usually lacking the sonic performance of pricier options. With MEMS drivers, the audio quality is greatly improved in affordable models that are half the price of the top-of-the-line Sony or Sennheiser noise-canceling earbuds. And with Cypress, xMEMS can offer audio companies the ability to improve overall sound quality without having to raise prices. 

xMEMS has also developed what it calls a DynamicVent to relieve occlusion in sleep earbuds. The component can automatically open or close depending on if the buds detect ambient noise like a snoring spouse. When open, the DynamicVent offers a semi-open fit like AirPods, but when it's closed the ear will be completely sealed off. The open vent should also keep sounds of your own breathing or the earbuds rubbing against a pillow from disturbing your sleep. xMEMS is showing off the DynamicVent at CES in a set of reference sleep buds equipped with its Cowell MEMS drivers.
