This co-operative action horror FPS takes you and your friends through the cities, swamps and cemeteries of the Deep South, from Savannah to New Orleans across five expansive campaigns. You'll play as one of four new survivors armed with a wide and devastating array of classic and upgraded weapons. In addition to firearms, you'll also get a chance to take out some aggression on infected with a variety of carnage-creating melee weapons, from chainsaws to axes and even the deadly frying pan.
Makes various improvements to the game, including: adding the MP5 SMG, allowing you to use melee weapons and throwables while incapped, giving melee weapons their own slot, and much more. Also includes my Improved Bots addon, which vastly improves the intelligence and capabilities of bot players. Check the changelog (icon in the top-right corner of the preview images above) for the full list of changes. The difference between the simple and advanced version of this addon is only which version of the Improved Bots addon is included.
There's something wrong with the main menu, on single player campaign.
