Just moments after Microsoft showed us L4D2 Valve throws up this official press release about the game and the trailer turns up online too. Expect this to happen a lot over the next couple of days.
Sequel to Best-Selling Co-op Thriller Coming This Holiday
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.
“A large part of how Left 4 Dead became 2008′s top-selling new IP on Xbox 360 and the PC was the custom-tailored gameplay made possible by the AI Director,” said Gabe Newell, president and co-founder of Valve. “With the knowledge gained from creating the original, new technology, and a passionate team, L4D2 will set a new benchmark for cooperative action games.”
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.
Introducing the AI Director 2.0, L4D’s dynamic gameplay is taken to the next level by giving the Director the ability to procedurally change weather effects, world objects, and pathways in addition to tailoring the enemy population, effects, and sounds to match the players’ performance. The result is a unique game session custom fitted to provide a satisfying and uniquely challenging experience each time the game is played.
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.
