Like the zombies it's filled with, Left 4 Dead 2 just won't stay down. Valve continue to update their co-op FPS with new features - this time shoring up the game's Steam Workshop support with an official release of their Extended Mutations. In effect, they've mutated the mutators to provide advanced scripting tools to the community, allowing them to tweak rules and create new game modes. Like adding tiny, shrunken undead. They'd be cute if not for the biting.

Valve say they'll be highlighting some of the best mutations on the official blog later in the week. For now, they recommend Holdout: "It is a multi-map Mutation that includes the concept of resources and buildable items. It was created to showcase some of the functionality of EMS and as a byproduct, it is pretty damn fun." Valve plan to continue supporting the top community mutations through official servers.

This latest update also marks the full release of other beta features, including Linux support - which has now been rolled out to allow testing on further builds and distros. You can find the full patch notes here.

Just as promised, Steam Trading Cards is now live. The virtual cards can be earned by playing participating games on Steam, trading with other users, or buying on the Steam Marketplace. Complete a set to create a badge, earn rewards and XP, and level up. The user with the highest Steam level at the end of the year gets to high five Gabe Newell while announcing Half-Life 3. In space.

In other true facts, I'm already hearing from users playing the Steam marketplace to profit off the cards' initial popularity. One user I spoke to has been buying low and selling high to pad his Steam wallet, even creating scarcity by buying up low-value cards in quantity. I'll keep an eye on marketplace prices as more users start trading the collectibles.

I was hoping to find a good deal on a 1952 Mickey Mantle card, but unfortunately, baseball isn't a participating game. You can see which of the games you own are participating here.

Good community content continues to flow from Left 4 Dead 2, a game we can't seem to stop championing for its healthy modding scene. Our latest praise is aimed at GoldenEye 4 Dead, an adaptation of the 1995 James Bond film and Nintendo 64 game that isn't afraid to bring original ideas to a setting most gamers are deeply familiar with.

Watch my playthrough with Tyler above.

After three years of labor, French development team Elseware Experience is finally ready to release DNIEPR, a custom Left 4 Dead campaign placed in the bleak Soviet-era ghost town of the Chernobyl Exclusion Zone.
I can't believe I didn't realize before now how perfect the abandoned Ukrainian city of Pripyat (also the subject of STALKER: Call of Pripyat) would be for zombie hordes and rampaging Tanks. Now that I’ve seen it in action, it’s chilling how much photos of Pripyat already look like set dressing for The Walking Dead.



This project is the kind of thing that makes you love gaming on PC. Three and a half years after Left 4 Dead 2 released, here we are with another completely new campaign with four new maps, an original story, an original soundtrack and custom models. If you'd like to show your support for the "hundreds and hundreds" of hours Elseware took to create DNIEPR, you can send them a donation at the bottom of this page.


DNIEPR will be available for download on May 20. If you haven’t played L4D2 in a while, this is a perfect excuse to reinstall and jump back in. If you need even more reasons, we've covered a plenty of great content mods for Left 4 Dead before.

There may come a day when preparing for the next chapter of a Left 4 Dead game will include wiping down your sweaty palms and taking a deep, deep breath. If you don’t, the zombies will get faster.

In remarks during the 2013 NeuroGaming Conference and Expo (via VentureBeat), Valve’s in-house experimental psychologist—Wait, hold on. Did you know that Valve employs an experimental psychologist? I wonder if he has lunch sometimes with the economist.

Anyway, Valve’s in-house mad scientist, Mike Ambinder, discussed experiments where players’ overall nervousness and agitation were measured, in part by recording sweatiness. If players began to show signs of nervousness or fear, the game would speed up. This new control scheme—mouse, keyboard, sweat-measuring skin pads—added another way for the player to interact with the game. Shoot zombie, reload pistols, keep calm. Signal for rescue, throw molotov, keep calm.

Ambinder also described other experiments in game design and biofeedback—which Valve has been talking about for a few years—including a version of Portal 2 that was played via eye tracking. Exploring the next generation of possible gaming inputs shows once again that Valve continues to operate, and plan, on a whole different level.

So good for you, Mike Ambinder. Just stay away from the mega-baboon hearts and everything will work out just fine.

Valve has thrown a bit more of its weight behind Linux with the release of beta builds of Portal and Left 4 Dead 2. If you own either (or both) games you should find that beta versions have materialised in your Steam library - along with Portal 2, according to some. The Linux build of the first-person puzzler has so far gone unheralded by Valve, but here's a blog post describing the latest beta version of Left 4 Dead 2. In addition to letting Linux users play Valve's zombie hit, the download acts as a "testing ground" for its new Extended Mutation System. Thankfully, you can try the beta on Windows and Mac too.

The beta version of Left 4 Dead 2 is the same size as the main game, so you have a hefty download ahead of you. (I assume the same is true of Portal.) Steam for Linux officially launched in February, so it hasn't taken too long to get Portal and L4D2 on there. Half-Life 2 next?

Resident Evil 6 is out on PC starting today, and as announced by Capcom last week, it will feature PC zombie-slayers Coach, Ellis, Nick, and Rochelle from Left 4 Dead 2 in the exclusive Mercenaries No Mercy mode. A new trailer shows them doing what they do best, but the crossover hop seems to have bestowed the foursome with a repertoire of hilariously dramatic melee moves. There's no reason why the barrel-chested Coach would choose to shoulder-check through a horde before roll-diving away to blast an RPG at point blank, but damn if it isn't stylish.

You can grab Resident Evil 6 on Steam for $40. The L4D2 cross-over content will be available free April 5th.
