Wolfenstein 3D, a first-person shooter, is a follow-up to the infiltration game called Castle Wolfenstein. The player becomes B.J. Blazkowicz, who is an allied spy. You can look forward to six exciting episodes. There are nine levels in each episode and also one secret level which can be activated by a hidden switch in one of the eight first levels. You might come across a maze full of enemies in this game. Sometimes you will be able to get silver or golden keys to open certain doors. Pay attention to everything you can find in a level. There will be things which will help you a lot, for example food or weapons. From the start you will have a knife and a pistol and later you will be able to find or pick up a machine gun and the Gatling will be dropped somewhere in the level.
