Apogee Entertainment operates as an indie video game developer and publisher based in Rowlett, Texas. Founded by Scott Miller in 1987, the studio pioneered the shareware model, releasing iconic titles like Commander Keen, Duke Nukem, and Wolfenstein 3D. After transitioning to 3D Realms in 1996, the Apogee name was revived in 2008 by Terry Nagy, a college friend of Miller, who later rebranded it as Apogee Entertainment in 2021 with Miller leading publishing efforts. The studio developed Residual, a survival platformer launched in 2021 on PC and Nintendo Switch, featuring procedurally generated worlds and crafting mechanics. Apogee Entertainment focuses on innovative indie games, mentoring developers to create engaging experiences for PC and console players.
