Trama:

Earthion is an upcoming aftermarket shooting game developed by Ancient primarily for the Sega Mega Drive. Physical MD versions will be published by SUPERDELUXE GAMES in Japan and by Limited Run Games in North America. The game will also get a 16:9 version for modern platforms. Earthion is published under the label YKGGG, a brand name covering all the retro-style games developed at Ancient. If Earthion meets success, Ancient will go on the venture of releasing video games designed for retro consoles. A separate version of the game for Arcade was confirmed by Ancient and published by exA-Arcadia, which features a new, exclusive mode that will not be available in the Mega Drive version.
