Parallax Software was a development studio best known for the Descent series. It was founded by Matt Toschlog and Mike Kulas in 1993. Prior to forming Parallax, Matt and Mike worked for subLOGIC and Looking Glass Technologies, writing simulations and 3D engines.

Parallax had offices in Champaign, Illinois and Ann Arbor, Michigan, and decided to split the company into two separate divisions in 1997: Outrage Entertainment and Volition. At that moment, Parallax Software Corp. ceased to exist.
