Wolfenstein 3D

Wolfenstein 3D is a first-person shooter with rudimentary 3D graphics and a successor to the top-down infiltration game Castle Wolfenstein. The game is divided into levels, each representing a flat plane divided into areas and rooms by a grid pattern of walls and doors of equal height. Each level is modeled after Nazi bunkers and buildings. To complete a level, the player must traverse the area to reach an elevator. The levels are divided into episodes, with the last level containing a boss fight with a particularly difficult opponent. As the player traverses the levels, they must fight Nazi guards and soldiers, dogs and other enemies while managing their ammunition and health supplies. Later versions of the game included the "Nocturnal Missions" expansion, but this first version did not.
