engine. The level design uses 90-degree walls and unvarying floor and ceiling heights in individual maps, limitations that are vestiges of the Wolfenstein 3D engine. However, the Rise of the Triad engine also includes features not possible with the original Wolfenstein 3D engine, such as elevation, panoramic skies, simulated dynamic lighting, fog, bullet holes, breakable glass walls, and level-over-level environments (made possible by "gravitational anomaly disks", suspended objects that collectively form stairs, floors, etc.). The level layouts were created with Tile Editor version 5 (TED5), which was also released with "Extreme Rise of the Triad" for users to customize their own maps. Developers of Incredible Power The team behind Rise of the Triad called itself The Developers of Incredible Power (DIP). Its name was created by Tom Hall, the lead designer of ROTT. Other members of DIP included Mark Dochtermann, Jim Dosé, Steve Hornback, Chuck Jones, Nolan Martin, Tim Neveu, William Scarboro, Joseph Selinske, Susan Singer, and Marianna Vayntrub. Rise of the Triad was the only game released by DIP. A second game that was planned, Prey, never took off, but its title and parts of the original design were eventually recycled by Human Head Studios. The team was disbanded, and some of the members worked on the bestseller Duke Nukem 3D. Others started their own companies or left the computer games business. Scarboro died from an asthma attack in 2002. Cut elements Several planned elements were cut from the game, including female versions of certain enemies, like Low Guards, Strike Force soldiers, and the Overpatrol. Originally the game was going to load both sets of guards into memory, then determine randomly which to place at each appropriate point. This had the side effect of making memory requirements much higher than normal for the time, so in order to conserve performance, the alternate versions of the enemies were removed. Stills of the alternate enemies can be seen during the credits, as "actors who were cut from the game". Other cuts survived, like the ROTT Reject Level Pack (stages that were cut) and some artwork (some can be found on the CD). There is a motion capture session that was not used in the final game, but can be found online. Release Game releases As most Apogee games, the game was distributed as shareware, with the first episode released for free. The shareware episode, which contains ten original levels, is titled
