Gingerfast is a monster from Killing Floor:Twisted Christmas. It was recreated as an animatronic by Fazbear Entertainment.
Gingerfast really puts the twisted in twisted Christmas. He is a lot more psychopathic then the other monsters.
Gingerfast starts in the Backroom with all the Christmas Animatronics. He moves in this pattern:Backroom -> Dining Room -> West Hall -> Repair Room -> West Hall Corner -> Your Office. You need to close the door to keep him out.
