Tripwire Interactive has been a mainstay in PC gaming since 2006. Over the years, it's put out beloved games like Red Orchestra: Ostfront 41-45, Red Orchestra 2: Heroes of Stalingrad, Rising Storm, and Maneater. It's also responsible for Killing Floor 2, the multiplayer horror FPS sequel to one of its first games, and a project that's become a modern classic in the genre since it came out in 2016. Last year, though, Tripwire announced that it's making Killing Floor 3, which will likely cause the current iteration's player base to dry up over time. More recently, the company also announced that it would no longer be updating Killing Floor 2 either and, though its servers will remain live, decided to see the classic shooter off in style with a final free weekend.
