The Dungeonmaster (originally Ragewar: The Challenges of Excalibrate and Digital Knights) is a 1984 American anthology fantasy film produced by Charles Band, and is split up into seven distinct story segments, each written and directed by a different person: Dave Allen, Band, John Carl Buechler, Steven Ford, Peter Manoogian, Ted Nicolaou and Rosemarie Turko.

[4] Paul Bradford (Jeffrey Byron) is a skilled computer programmer who lives with his girlfriend, Gwen (Leslie Wing), and "X-CaliBR8", a quasi-sentient personal computer that Paul programmed and which he interacts with via a neural interface.

One night, Paul and Gwen are both transported to a Hellish realm presided over by Mestema (Richard Moll), an ancient, demonic sorcerer who has spent millennia seeking a worthy opponent with whom to do battle.

Having long defeated his enemies with magic, Mestema has become intrigued with technology, and wishes to pit his skills against Paul's, with the winner claiming Gwen.

Most of the challenges involve Paul using his X-CaliBR8 wristband to shoot people, monsters, and objects with laser beams.
