Excellent co-op kill-o-geddon Killing Floor now has Steam Workshop support, letting fans share maps, mods and weapons. The most popular mods include a version of Killing Floor that uses Doom 2 assets, a map set in hell, a version of classic Counter-Strike mod, Gun Game and a scythe. That's a pretty good cross-section of the sort of bonus extras we can expect from Killing Floor's active modding community.
Red Orchestra 2 will be getting Steam Workshop support soon as well. To celebrate, a Tripwire Steam bundle has been on sale all weekend at 66% off. There's still seven hours left on the deal, which includes Killing Floor (and all DLC character packs), Red Orchestra 2, Red Orchestra: Ostfront 41-45, The Ball and Dwarfs!?
