The best place to get cheats, codes, cheat codes, walkthrough, guide, FAQ, unlockables, trophies, and secrets for Killing Floor 2 for PlayStation 4 (PS4). They enable features that are similar to cheat codes, for example you could get unlimited health, ammo etc. Welcome to the Cheatbook Trainers section! Trainers are programs that allow you to alter the way the game works so that you could cheat. This is more of a post to tell you that it does indeed work. If you managed to get into the Killing Floor 2 beta early, awesome! However, I wanted to see if Cheat Engine worked on KF2 like it did on KF1, and well, it does.
