Eschatos

Eschatos[a] is a scrolling shooter, developed and published by Qute, which was released on April 7, 2011, for the Xbox 360. Despite the original Xbox 360 version only being released in Japan, it was a region-free release. A version for Microsoft Windows has also been released and was published by Degica. Apart from the main game, two previous Wonderswan games by the developer, Judgement Silversword and Cardinal Sins, came bundled with the Xbox 360 release of Eschatos.

Eschatos takes place in the 22nd century where a mysterious organic alien matter - known only as the Purple Erosion - has taken over The Moon. After covering 75% of The Moon's surface, the aliens launch an attack on the Earth using flying saucers to deploy trajectory weapons and ships. The player is tasked with stopping the invasion using a fighter ship capable of great attack and defense technology.
