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).
Crusader: No Remorse
"Crusader: No Remorse" was developed by Loose Cannon Productions, a division of Origin Systems. It was directed by Tony Zurovec, whose chief inspiration for the game was "Castle Wolfenstein". The game uses an advanced version of the "" isometric view engine featuring full SVGA graphics. The game's audio uses a specially made engine, called Asylum Sound System, which employs MOD files rather than General MIDI, in order to provide good quality without relying on expensive hardware. Each mission and intermission level has its own track. The soundtracks for both games were composed by Andrew Sega and Dan Grandpre of the now-defunct Straylight Productions.
