The sequel to the 2008 Multiplayer Game of the Year, Left 4 Dead 2 is due out November 17 on Microsoft Windows PC and Xbox 360. Value is making the PC version while Certain Affinity is handling the port on the XBOX 360.

In L4D2 the AI Director has been improved to encourage more participation by players, forcing players through difficult gauntlets to reach the extraction point, and the ability to alter elements of the level such as placement of walls, lighting, or weather conditions. The AI Director will also be improved to reward players for taking longer or more difficult paths through each episode by providing more useful equipment, such as incendiary ammo, along these riskier paths, and even alter elements of the levels to create varied paths based on the choice of these paths.

Players will have access to more and improved weapons, including new melee weapons such as a frying pan, an axe, baseball bat, cricket bat, and chainsaw, and improved guns such as a silenced sub-machine gun, and a more-precise assault rifle. Also, totally new weapons like a grenade launcher and an AK-47. While the players will mostly encounter normal infected foes, there are “special infected” foes that possess unique abilities that require unique tactics to defeat or avoid. In addition to those introduced in the first game, Left 4 Dead 2 includes the Charger, a larger creature that can move fast but with low health that can leave a player helpless, and the Spitter, which spews a ball of mutated phlegm which covers an area of ground and eats away at survivor’s health for every second they are in it. Existing specials will also be adjusted; for example, the infected Witch, fixed to a single spot in Left 4 Dead, will be able to roam during daytime levels, a featured referred to by Valve representatives as the “Wandering Witch”.
