We've now faced so many zombie apocalypses that it's amazing the shambling menace can elicit even the mildest increase in heartbeat. So while Killing Floor remains an enjoyable co-op FPS, any change to its morbid monsters is welcome. Especially when that change is in the form of in the form of H.R. Giger's face-smothering, acid-dripping, chest-bursting beasties.
That's what you get in Killing Floor: Aliens, an extensive mod that swaps out the game's setting, weapons and, most importantly, enemies for those from James Cameron's action sequel. Nearly two years in development, the mod's team say of the project, "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."
There's a whole zoo full of Xenomorphs, from the tiny facehuggers to the giant Alien Queen, along with new weapons, maps and perks. You also get a full roster of characters from the movie - including Ripley - who the mod's makers claim now play and sound like their cinematic counterparts.
Download and installation instructions are available from the mod's website , or you can go here and install through the Steam Workshop.
