It's the one I mentioned on the Sister Location page. (It's called FNaF 2 Endless Nightmare Mod) In the official game, these squares move around the game map and keeps track of the characters. They are invisible, unless you make them visible by editing the game, which this mod did. It's one of the cheats you can get in endless mode, but there is also a mod the dev set up that's specifically for FNaF 2 cheats. (radar, unlimited flashlight, music box always wound)
Is this a real mod?
