Volition, Inc. is a video game developer for consoles and Windows-based PCs. Volition is located in Champaign, Illinois. The company was created when Parallax Software (developers of the critically-lauded Descent series) was split in two. The other half was the now-defunct Outrage Entertainment who developed Descent³ and Alter Echo.

With Interplay Entertainment as a publisher, Volition, Inc. developed the FreeSpace series of space simulation computer games. As Interplay tumbled towards bankruptcy, Volition, Inc. was acquired by THQ in September 2000. Since then, Volition, Inc. has developed several acclaimed titles including the Red Faction series, the Summoner series, The Punisher, and the Saints Row series.

In their games, Volition, Inc use the company "Ultor" usually as the main "evil" company.

Volition is currently working on the upcoming release of the third in the Red Faction series, Red Faction: Guerrilla, and a possible sequel to Saints Row 2, Saints Row 3.
