- Optimized version of Extreme Custom Night. NOTE: This game's timeline, and story, doesn't take part what so ever from the original series of Five Nights at Freddy's game by Scott Cawthon. You have finished your job of a night-guard last week, and now you have nightmares of your own. The memories are still awake in your head, and to stop the terror, you must survive against all of them! So go on, create your own chemistry, see if you can face the twisted animatronics! Set the difficulty of each animatronic from 0-20! Each animatronic has a unique ability! Challenge others by gathering points from the difficulty of the animatronics! New menacing animatronics are on their way to come and haunt you... Special thanks to HayStudios, and to Scott Cawthon. This fan-game wouldn't have been done without them, so huge credits from me!
