Wondering what to do with your three day weekend? Turtle Rock Studios is hoping you'll (re)visit its co-op shooter Evolve, courtesy of a few days of free access on Xbox One and PC. Even if you already own it, it may be time to knock the dust off because besides the flood of players, it's unlocking all the DLC for you to try, and just permanently unlocked a new monster, the Meteor Goliath. Thanks to its 4-on-1, primarily multiplayer setup, having a strong base of online players is key, and this is one way to try and refresh the ranks. The free preview is already under way, wrapping up on the 7th, at 11:59PM PT on Xbox One, and at 10AM PT on PC.

War Child, a London-based charity that aims to improve the lives of children affected by war, is collaborating with influential developers to create a collection of games titled HELP: Real War is Not a Game. Participating developers include 343 Industries (Halo 5: Guardians), Bossa Studios (Surgeon Simulator), Creative Assembly (Alien: Isolation), Team 17 (Worms) and Hinterland (The Long Dark), all of which will participate in a six-day game jam organized by War Child. This means the studios will have just six days to create the games for HELP, and the full compilation will be sold digitally in late March 2016. Proceeds will go toward funding War Child's efforts in global conflict zones.

Here's a tough choice: would you rather play a game about a gardening robot that experiments with new methods of character animation, or a ridiculous time-travel action game that throws paradoxical caution to the wind? Lucky you -- you don't have to decide at all. On today's Engadget Playdate, we're playing both: Ubisoft's procedurally animated Grow Home and absurdly silly Super Time Force Ultra. Both are new to PlayStation 4 owners this month and free for subscribers of PS Plus. Are they worth the monthly dues? Join me and Tim Seppala at 6PM ET (3PM PT) right here, on the Engadget gaming homepage or at Twitch.tv/Joystiq to find out.

The dark, freezing woods of Sweden are the perfect breeding ground for terrifying tales of naughty children who get what they deserve. This week, Simogo -- the developer of beautifully macabre game Year Walk, and mysterious narrative experiences Device 6 and The Sailor's Dream -- released a free, illustrated ebook collecting a handful of five re-tooled, scary Swedish folk tales. It's called Year Walk Bedtime Stories for Awful Children, and it's available in English, French, Spanish, German and Italian. "We think obnoxious children all over the world deserve dark nightmares," Simogo writes.

OSVR headset

The Open Source Virtual Reality (OSVR) headset will get a significant upgrade soon. Gaming peripheral company Razer announced the OSVR program back in January, but the first prototype headset was an underwhelming affair with uncomfortable ergonomics and a so-so display. That wasn't really the point, though. Rather than a single company aiming to dominate the VR market, OSVR is a loose band of hardware and software companies hoping to do for virtual reality "what Android did for mobile." Since then, OSVR has continued to work on improving the system, adding features like positional tracking and, aptly, Android support. The idea is to perfect the basics, open-source the hardware and software, and let anyone build on and improve it.

Batman: Arkham Knight was supposed to be the perfect swansong for Rocksteady's Dark Knight trilogy. While the game was received positively on PS4 and Xbox One, the PC version was a mess -- so bad, in fact, that Warner Bros. eventually pulled it completely. That was in June and only now, 10 weeks later, are PC players getting a patch that should fix the most glaring issues. The new update claims to solve the game's fluctuating frame rate, while also improving its overall performance on all GPUs. Warner Bros. says it'll also remedy any low resolution textures and add a deeper set of in-game settings for you to play with. If you were hoping to buy the game now that's in a better state, bad news -- Arkham Knight is still unavailable to purchase on Steam. Perhaps that's an indication of where the game now stands -- better than before, but still a little way from what PC players deserve.

Even if you spent $399 on the ultra-crazy edition of Borderlands: The Handsome Collection there was a pretty gaping hole in it. No, I'm not talking about what that purchase did to your bank account, I mean the anthology's distinct lack of the series' first game. Well, for Xbox One owners that's changing because the Vault Hunters' first trip to Pandora was recently added to the list of Xbox 360 games playable on Microsoft's newest console -- something that was teased back at E3 this year. Folks in the Dashboard Preview Program can start playing right now, of course, but everyone else who got stuck on Dr. Ned's zombie island (Microsoft says all save files, add-on content and achievements will transfer over) have to wait until the feature launches to the public this November. You still had a few lunar side-quests left to finish for Handsome Jack in the meantime anyhow, right?

Back to school. Those three words can strike fear in even the hardiest of kids. We're celebrating the beginning of the semester a little differently, because, well, that's what we do on Playdate. Rather than spend the afternoon quoting Billy Madison, we're going to be playing through No PIneapple Left Behind, a game that skewers the politics of the American education system. And who better to talk about it than Seth Alter, the former teacher who developed the game? No one, that's who. So join us here at 6 pm ET / 3 pm PT as Sean Buckley and myself walk through these pineapple-filled halls for two hours on Twitch. You can tune in here on this post, Twitch.tv/joystiq or even the Engadget Gaming homepage. And no, there's no need to bring an apple for us -- just being a good sport in chat is reward enough.

Today we got our first glimpse of the BBC's upcoming Grand Theft Auto docudrama, which examines the game's development and public scrutiny in 2002. The Gamechangers, starring Daniel Radcliffe as Rockstar president Sam Houser, covers the franchise's growth in the PlayStation 2 era and the criticism that followed regarding its portrayal of violence. Bill Paxton is playing Jack Thompson, a former attorney that famously campaigned against the series, and based on this new trailer it's clear their thorny relationship is the centerpiece of the show. In May, Rockstar said it would be filing a lawsuit against the BBC over trademark infringement -- the developer said it's had "no involvement" with the project and seemingly disapproves of it altogether. The broadcaster appears unfazed by the legal action though, as it's scheduled to air on September 15th, at 9pm on BBC Two in the UK. If you live elsewhere, however, there's no word just yet on an international release.

There was a brief period when Bandai Namco was trying a free-to-play model for its bigger franchises like the venerable Soul Calibur fighting series and its arcadey Ridge Racer. The latter shut down in 2014, and the former will suffer a similar fate pretty soon. Come November 30th, the PlayStation 3 exclusive Soul Calibur Lost Swords closes its virtual doors while sales of in-game items stop about a month prior on October 27th, according to GamesIndustry.biz. From September 16th to September 30th though, Bandai Namco is hosting some commemorative "ranking quests" to mark the occasion. Are you among the game's over two million players and are already mourning its passing? Let us know in the comments. And hey, who knows, this could point toward a Soul Calibur hitting modern consoles sometime soon -- possible silver lining and all that.

Game-tech powerhouse Epic Games and its Unreal Engine are capable of some seriously impressive stuff, and now the North Carolina-based outfit wants you to experience what it's capable of in the virtual reality space. "Showdown" is the demo that the outfit's been showing off at industry events for the past year or so (I got to try it at CES back in January) and it's by far the most bad-ass bullet-time walk toward a hulking, missile-happy, bipedal robot I've ever experienced. The path is predetermined, sure, but as the street explodes into chaos around you, it's entirely possible to duck down or peer around objects like pop cans or even cars as they hurtle toward you in slow motion.

The November release Valve's fancy Steam Controller is right around the corner, and the company seems to be getting the rest of its platform ready for launch day. Specifically, Valve is giving Steam's Big Picture Mode a visual overhaul, redesigning UI navigation in the TV-interface's game library with a more dynamic layout, making tweaks to game-specific pages within that library and updating the look of user profile pages. Valve is also adding FLAC, OGG, Vorbis and M4A support to its music player, as well as experimental Streaming-host support for Macs. Curious? Try it out for yourself by opting into the Steam beta client in your settings menu, or simply check out the gallery below.
