Descent 3 is the third game in the line of Descent computer games, well known for the use of six degrees of freedom and true 3D rendering technology.

Descent 3 constituted a major technical upgrade over its two predecessors, introducing many ground breaking graphical techniques like portal rendering, procedural texturing and advanced lighting. Interplay has plans to create a sequel if it secures funding for the game's development, however right now Interplay is developing Descent WiiWare.
