Killing Floor: Toy Master (2014)

In a free, add-on mod for Killing Floor, created by David Hensley (with help from Killing Floor originator, Alex Quick), you can fight off the bizarre and warped toys of someone's nightmare, that are hell-bent on finishing you off. All the standard Zeds are replaced with evil toys, set in the Devil's Dollhouse map.

Storyline

Set in possessed doll house, your goal is to protect the jumping chests from the assaulting waves of toys. Failing to do so results in an epic boss battle, A giant jack in the box.
