Unreal is a series of first-person shooter video games developed by Epic Games. The series is known for its exhibition of the namesake Unreal Engine that powers the games and is available for other developers to license.
Publishing rights for the series have changed hands several times. GT Interactive was the original publisher and would be later succeeded by Infogrames, Atari, and Midway Games.
In December 28, 2022 Epic Games made the decision to delist every Unreal game from all major digital storefronts following their move to support their own Epic Online Services, and in November 14, 2024 they gave permission for Unreal and Unreal Tournament to be preserved and distributed for free on the Internet Archive
Guinness World Records awarded the series with three world records. These records include, "First Console Game to Receive a Downloadable Patch", "First Console Game to Support Player Modifications" and "First Game to be Created Using the Unreal Engine".
