Any and all things Five Nights at Freddy's!
Some sweet info:
FNAF 2 came out on November 11th, hours after the 2 night demo came out. It is created solely by Scott Cawthon (www.scottgames.com)
and features 11 animatronic characters intent on stuffing you into a suit. The animatronics include Balloon Boy, Marionette, or "The Puppet", Toy/Old Bonnie, Toy/Old Freddy, Toy/Old Chica, Foxy, Mangle, and Golden Freddy. An extra endoskeleton sometimes appears in the camera, but is not actually hostile.
