Left 4 Dead 2 Announced
Quoted from Steam News
"June 1, 2009 - Valve, creators of best-selling game franchises (such as Half-Life and Counter-Strike) and leading technologies (such as Steam and Source), today announced Left 4 Dead 2 (L4D2), the sequel to the best-selling and critically-acclaimed co-operative multiplayer thriller.
Coming exclusively to Xbox 360 and PC, L4D2 promises to set a new benchmark for co-operative action games and become one of 2009's marquee titles.
Set for release on November 17, the title adds melee combat to enable deeper co-operative gameplay, with items such as a chainsaw, frying pan, axe, baseball bat, and more.
Featuring new Survivors, boss zombies, weapons, and items, Left 4 Dead 2 offers a much larger game than the original with more co-operative campaigns, more Versus campaigns, and maps for Survival mode available at launch."
