Wolfenstein
Silas Warner, an American programmer and an employee of software company Muse Software, was a pioneer of early video game development, especially the stealth genre. He had access to computers in college, and when he worked for the IBM Mainframe architectures before joining Muse Software. The computer he used for game-development, P.L.A.T.O., was one of the firsts with multiple functioning terminals and an example of early computer networks. Warner developed, with P.L.A.T.O., a series of classic video games like his flight simulator and arcade shooter. Inspired by the arcade shooter video game "Berzerk" and the 1961 war film "Guns of Navarone", he developed "Castle Wolfenstein", a stealth-adventure video game in which the player controls an unnamed American prisoner of war as he steals German files containing secret war plans, while avoiding, disarming or at times killing hostile guards and trying to escape the fortified Nazi stronghold 'Castle Wolfenstein', set in World War II. The game was published in 1981 by Warner's company M.U.S.E. Inc. (Muse Software).
Return to Castle Wolfenstein
In the German version of the game, it avoids making direct reference to Nazi Party and the "Third Reich", in order to comply with strict laws in Germany. The player is not battling Nazis but a secret sect called the "Wolves" led by Heinrich Höller, whose name is a pun of the original character Himmler (Himmler roughly translates as ""Heaven"er", Höller as ""Hell"er"). The Nazi swastika is also not present: the German forces use a Wolfenstein logo which is a combination of a stylized double-headed eagle prominent in most Nazi symbolism, a "W" (standing for Wolfenstein), and the "Quake III: Team Arena" "QIII" logo (the game engine and network code that "Return to Castle Wolfenstein" is based upon). The "W" eagle logo is prominently seen on the cover art for the American version.
