Our current favorite game is getting an undead sequel. According to uber-developer Valve, Left 4 Dead 2 ($60) "takes place at roughly the same time as the original, and leads four new survivors through the southeastern region of the U.S., from Savannah, Georgia to New Orleans' French Quarter." L4D2 adds melee combat (chainsaws, frying pans, axes, baseball bats, etc.), a new group of survivors, new zombies and creatures, co-operative campaigns, more Versus campaigns, maps for Survival mode, and more. Find it for Xbox 360 this November.
