Gea vs CoDOS is the first game developed with ZEngine, a multiplatform 3d engine. Currently supported platforms are: NDS, Symbian s60 and PC. ZEngine is not currently available for download, but it will be pretty soon.
In Gea vs Codos you take control of GEA a super heroin that has to capture the photons trapped in the atmosphere by the greenhouse effect. Co2 particles won't make the things easy for you. This is a one button game, so only key up will be used.
