Garry's Mod Five Nights at Freddy's

Game description:

Check this add-on for your Garry’s Mod game! Now you will bring some slight touch of horror to the all-creative process. Due to this feature, you will let Freddy and his friends animatronics enter the scene! They will run around, doing their nasty things. And building won’t be your main aim from the moment animatronics appear. Now you will have to survive! Bring the new life to both FNaF and Garry’s Mod experience! Combine two amazing titles in one and see what happens.
