Eschatos is a vertical shoot 'em up developed for the Xbox 360 by Qute. One of Qute's previous games, Judgment Silversword -Rebirth Edition- (originally released for the WonderSwan), and its update Cardinal Sins - Recycle Edition are included on the disc.
First print editions of the game were bundled with a soundtrack CD. The game is region-free and was originally scheduled to be released on March 24, 2011. However due to the March 11 Tohoku earthquake, the release was delayed. The game was finally released on April 7, 2011. A budget priced version titled Eschatos (Wonder Price) was released on July 14, 2012.
A DLC pack was released for 560 Microsoft Points on April 25, 2012 which allowed players to use the Arrange Soundtrack during gameplay.
