Ultima VI: The False Prophet, released by Origin Systems Inc. in 1990, is the sixth part in the role-playing video game series of Ultima. It is the third and final game in the "Age of Enlightement" trilogy. Ultima VI sees the player return to Britannia, at war with a race of gargoyles from another land, struggling to stop a prophecy from ending their race. The player must help defend Britannia against these gargoyles, and ultimately discover the secrets about both lands and its peoples.

Ultima VI continues to advance the technology of the Ultima series. The game world is larger, with a 1024x1024 tile map seamlessly connected and to scale. World interactivity is further increased with object manipulation, movement, and crafting. Graphics and sound are likewise advanced with the use of new sound card technology and VGA graphics cards, and the user interface is streamlined with the use of point-and-click icons.
