Insanity is a challenging fangame that can be downloaded for free. The game is based on FNaF games and it promises to bring you a lot of challenges. In the game, there are plenty of animatronics who become very insane and merciless when the night comes. You will return to FNaF 2 and try to check out something that Scott Cawthon alluded before. Surely you will come across a lot of animatronics, so you must fight them off and protect yourself. Your goal is to survive all dangers! Have fun!
