AKF is one of the most comprehensive mods to date released for Killing Floor. The aim of this mod was to bring the feel and scope of James Cameron's Aliens to Killing Floor while in one hand remaining true to the franchise and in the other ensuring that it still retains the feel of Killing Floor.
A quick hotfix to address some file discrepancies. Please let me know if there are any additional problems. We will probably be rebuilding the Steam Workshop entries at some point as well as that has been problematic, probably next update. Extract these files to your \killingfloor\system\ folder. Overwrite when asked.
