Microsoft Game Studios has signed up for an exclusive Xbox Live Arcade title from Undead Labs codenamed Class3. There is no release date in sight currently for the game, but the title has zombies in it, so when you hear undead moans, you'll know it's coming.

Developer Undead Labs is billing the third-person action title as an open-world zombie title where players choices – like where and with what to fortify a settlement – will affect what happens later in the game. Class3 also features drivable vehicles, melee combat, lots of gore, rescuing survivors, foraging, and more. The game will have two-player online co-op and splitscreen play.

Undead Labs hopes that Class3 is just the beginning, and wants to use the game as a stepping stone to a full-fledged Xbox Live MMO that it is already planning under the moniker Class4.
