Devil's Dollhouse is the sole map available in the Toy Master mod for the original Killing Floor.

You start out in a creepy bedroom before being sucked into it's tiny dollhouse. There you face waves of evil toys attempting to break open a chest. At the conclusion you face Jack before being transported back to the (now clean) bedroom.

It can only be played in the Short game length (ie. four waves and a boss), and cannot be played in the normal Survival Mode.

In-Game Description
