Wolfenstein

''Wolfenstein'' is a series of alternate history World War II video games originally developed by Muse Software. The majority of the games follow William "B.J." Blazkowicz, an American Army captain, and his fight against the Axis powers. Earlier titles are centered around Nazi attempts to harness supernatural and occult forces, while later games are set after the Nazis successfully implement various science fiction technologies to achieve victory in World War II.

The first two games in the series, ''Castle Wolfenstein'' and ''Beyond Castle Wolfenstein'', focused on stealth-based gameplay from a top-down perspective. Beginning with id Software's ''Wolfenstein 3D'', they shifted to, and helped popularize, the first-person shooter genre. After ZeniMax Media acquired id Software, including the ''Wolfenstein'' franchise, developer MachineGames became the series' primary developer. Provided by Wikipedia
