Fate/EXTRA, released in July 2010, is a dungeon RPG made by TYPE-MOON and Image Epoch, and published by Marvelous Entertainment for the PlayStation Portable as a re-imaging of the Fate/stay night visual novel series. The game's scenario was written by Nasu, and the artwork is done by Wada Rco. In November 2011, Aksys Games released the game in the U.S., and Ghostlight later released the game in PAL territories in January 2012.

The game features character from the Fate universe as well as all-new characters and Servants, and takes place in an alternate universe that diverged from the original Fate universe sometime in the 1970s. Most of the story takes place in a virtual world called Moon Cell, where a system called Serial Phantasm, or SE.RA.PH, tries to replicate the Holy Grail War.
