It's time for another monthly Games for Windows Co-Op Night, and this month things have gotten evil. We're taking Capcom's Resident Evil 5 onto the town this Friday night for a date with the dead. Or undead. Or diseased. Anyway, read on to find out how to join.

Dawn of War 2: The Last Stand is out right now, simply fire up Steam and you'll be updated to the latest version of the game and all the co-op goodness it contains. Need the lowdown on just what you are getting? Then check out this post on the official community blog.
As you may know, we're going to have a Games for Windows Co-Op Night this Friday Starting at 9PM EDT. While Relic is holding their own contest, we thought we'd have a little contest of our own - courtesy of the Games for Windows team.
Dawn of War 2's free update goes live on Wednesday, and with it comes a brand new survival mode called The Last Stand. If you read our preview from PAX and checked out the video, you know what to expect. Three players team up and face off against 20 rounds full of enemies and surprises.
What's more, players can level up their character and unlock unique items and bonuses for use in the game. To celebrate the launch Relic is holding a contest where you can win a signed poster, a miniature, and a t-shirt. The only thing you need to do is reach and complete wave 20! And in the true spirit of co-op, each member of your team wins the same prizes.

Our next Games for Windows Co-Op Night is here, and we'll be playing a Relic RTS. No, not Dawn of War 2 - Company of Heroes Tales of Valor! Read on to find out how to join up for Operation Stonewall against waves of the Nazi army!
This month we're taking the Activision's Call of Duty: World at War for a spin on the PC. We'll be playing the campaign mode in co-op as well as the ever popular Nazi Zombie mode! With any luck the latest patch will be out providing us with a new four player co-op zombie map!
