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).
Charles Cecil
In 1989, when Cecil was still working at Activison, he decided to set up his own development studio. He contacted Tony Warriner, who had worked with him at Artic Computing and Paragon Programming, and Warriner brought in a fellow programmer, David Sykes. Together with Noirin Carmody, his then-partner and General Manager at Activision UK, they founded Revolution Software (March 1990). The company was originally located in Hull, but moved to York in 1994. Besides becoming Revolution's managing director, Cecil would focus from the start on writing and design. At that time the graphic adventure genre was dominated by LucasArts and Sierra On-Line, and they wanted to create something in between, an adventure game that didn't take itself too seriously, but did have a serious story. For Revolution's first title, Cecil conceived with others an innovative game engine, called Virtual Theatre, and the engine itself was designed by Tony Warriner. The result was Lure of the Temptress (1992), and though it was their first product, it became one of the successful games that would follow. For the second title, Beneath a Steel Sky (1994), often referred to as a cult classic, Cecil contacted comic book artist Dave Gibbons. He had met Gibbons when he was still at Activision, and he admired Gibbons's work on "Watchmen". Gibbons became involved in the design of the game, and their collaboration would inspire Cecil's next move.
