The Troopers' Playground is a single-player episode for Doom II. It was created by Matthias Worch. The Trooper's Playground contains nine regular levels and two deathmatch-only maps. The episode features a custom status bar and new textures. A Dehacked patch is used to create a new enemy, the "Evil Trooper", which is a reskin of the regular SS Nazi monster. The Evil Trooper looks like a green Doom marine without the helmet.
