Terror in Christmas Town

Another Doom clone made with the Pie 3D Game Creation System where you have to rescue Santa's frozen elf held captive by the evil polar bear king. It has Wolfenstein-like 3D graphics. Although you use heavy weaponry (shotguns and so on) this is not a gory game. The graphics, sounds and gameplay are all fairly basic. The graphics have a mildly winter/Christmas related theme, and there is an inventory system that is a bit more complex than usual in games of this type.
