Ritual Entertainment was a computer game software developer established in 1996 and based in Dallas, Texas. It was formerly known as Hipnotic Interactive, during which period they began development of their signature computer game SiN.
Members of the Ritual development team have contributed game assets to other titles such as 25 to Life and American McGee's Alice, and are also the creators of "Übertools" for id Tech 3, which has been licensed for a number of other games.
On January 24, 2007, developer MumboJumbo announced the acquisition of Ritual Entertainment.

Several months after the acquisition, community relations manager Steve Hessel left the company to join Splash Damage.Thearrel McKinney, a former employee of Ritual who left in 2003, also founded Mangled Eye Studios, the developer of 2009's Dark Salvation.
Prior to the announcement, on December 6, 2006, Ritual announced the appointment of Ken Harward as the company's new studio director.
