Under Defeat is a shoot em up video game developed by G.rev and released in Japanese arcades in 2005. The game takes place in an alternate reality during World War II, where players control German-speaking characters (dubbed the Empire ) fighting against English-speaking characters ( the Union ). Their vehicles are patterned after those of real-life Allied and Axis powers. A port for the Dreamcast was released in 2006 and marketed as the last game for the system, although two more were released the following year. The game was commercially successful, but received average reviews from critics because of its traditional and derivative gameplay.
