Valve has acquired Turtle Rock Studios, the Orange County-based developer behind Left 4 Dead, a multiplayer coop that uses the Source engine.
The merger of the two companies extends Valve’s development team and provides the company with a new studio in southern California.
Valve and Turtle Rock aren’t exactly strangers since the two have collaborated on several projects, including a number of Counter-Strike: Source maps, Condition Zero, and the Xbox port of Counter-Strike.

Just when I decided to reinstall my old copy of Half-Life 2, news of an interesting mod pops up. Anyone ever heard of Zombie Panic? Notice that I’m a sucker for games related to ninjas, zombies, and samurai, so don’t be surprised when I start drooling over this new mod.
Zombie Panic is a multiplayer that pits humans versus zombies. The session begins with just one zombie (can’t an entire team choose to play as zombies?), but whenever a human is slain, he respawns as one of the undead. The human side wins when they wipe out the zombies.

That’s right–you can drive around huge open spaces with Eli Vance’s hot daughter. Wanna see how it looks? Of course you do. Watch the video below:

I’m just surprised how the gal manages to stay in the vehicle even without wearing a seatbelt.
