Welcome to 3D Realms
Fire Power Matters
3D Realms (Apogee Software, Ltd.) is a Texas Limited Partnership whose General Partner is Action Entertainment, Inc., a Texas Corporation.
Since 1987, Apogee Software, Ltd. has been a multifaceted pioneer and innovator in the PC gaming industry. Apogee's first breakthrough was in shareware marketing. Known in the shareware industry as the "Apogee model," our breakthrough method of releasing a portion of a full game (an "episode") as shareware (years before the Internet became popular) was risky and innovative, and done well before other PC game publishers released demos of their games -- now standard practice.
Among other innovations popularized by Apogee in our early years include cheat codes (standard practice for our games as far back as in 1987), level warps and the so-called "god" invincibility mode. Apogee's games, and later 3D Realms' games, have always included skill levels and save/load game options, both very rare in PC games in the late 80's and early 90's.
