From Valve (the creators of Counter-Strike, Half-Life and more) comes Left 4 Dead, a new kind of action game for the PC and Xbox 360™ that features single player, co-op and multiplayer game modes.

Set in the immediate aftermath of the zombie apocalypse, L4D offers four expansive "movie campaigns" that challenge you and your fellow survivors to battle thousands of swarming zombies as you travel across the rooftops of an abandoned metropolis, through rural ghost towns and pitch-black forests. In addition to the movie campaigns, Left 4 Dead features a Versus mode that allows you to play as the Boss Zombies.

In the America's Army game, players are bound by Rules of Engagement (ROE) and grow in experience as they navigate challenges in teamwork-based, multiplayer, force versus force operations. In the game, as in the Army, accomplishing missions requires a team effort and adherence to the seven Army Core Values. Through its emphasis on team play, the game demonstrates these values of loyalty, duty, respect, selfless service, honor, integrity and personal courage and makes them integral to success in America's Army.
