Capstone Software

Capstone Software was a subsidiary of IntraCorp, a Miami-based computer and video game company. Founded in 1984, Capstone created first-person games such as Corridor 7: Alien Invasion, William Shatner's TekWar and Witchaven, and is also known for releasing games based on movie/TV licenses. Capstone's first-person games used the Wolfenstein 3D engine, and later, the Build engine.

IntraCorp went bankrupt in 1996 and shut down all its operations, including Capstone Software. Capstone's last game, Corridor 8: Galactic Wars, never left the prototype stage and was never released. Capstone became VRTech, providing first-person buildouts of new construction condominiums using the Build engine. It eventually closed down.
