Record of Agarest War Zero, known as Agarest Senki Zero (アガレスト戦記 ZERO Agaresuto Senki Zero?) in Japan and Agarest: Generations of War Zero in Europe, is a tactical role-playing game developed by Compile Heart and Red Entertainment. It was published in Japan by Idea Factory on June 25, 2009 for the PlayStation 3. It is the prequel to the 2007 game Record of Agarest War.

An enhanced port of Agarest Zero was released for the Xbox 360 titled Agarest Senki Zero: Dawn of War. The Xbox 360 version contained extra content not found in the PlayStation 3 version of the game, such as costumes, CGs and more.

Both versions feature an extra mode where you can return to the maps from the previous game, and unlock characters via the PlayStation Store or Xbox Live Marketplace.
