Left 4 Dead 2

Left 4 Dead 2 is a sequel to Valve Corporation's Left 4 Dead. It was announced at E3 2009 with a trailer and will be on both the PC and Xbox 360. Development for Left 4 Dead 2 started after the release of the first game, building off ideas from the development team to make the next game "bigger and better".

The game features five new campaigns, new weapons modified from existing types and new melee weapons. The AI Director has been improved to encourage more participation by players, forcing players through difficult gauntlets to reach an extraction point, and the ability to alter elements of the level. The AI Director was also improved to reward players for taking longer or more difficult paths through each episode by providing more useful equipment along these riskier paths.

The game is set in the Southern United States, starting in Savannah, Georgia and ending up in New Orleans, Louisiana. Four new survivors are introduced, with their backstories provided through dialogue in the game. The survivors include Coach, a high-school football coach, Rochelle, a reporter for a local cable company, Ellis, a boy mechanic, and Nick, a conman.
