Castle Wolfenstein is the first game in the legendary Wolfenstein series. This stealth-action shooter adventure, developed by Muse Software, was first released in 1981. The game is set in Castle Wolfenstein, which has been occupied by German Nazis. The hero must navigate through numerous mazes, locate a package of documents, and steal it. Furthermore, the hero must stay alive throughout the mission, as failure to do so will result in a mission failure.
The beauty of the game lies in the fact that it can be completed quietly, without killing or exposing oneself, or players can choose to tackle the levels loudly and brightly, engaging in unequal battles with enemies.
