Battlecorps (Feb 11, 1994 prototype)
Discuss this release on the boards here!
Xnz136 has kindly donated his early preview build of Battlecorps, a mech game for the Sega CD. Built in February 1994, it predates the final version by a full 6 months. There is a simple level select and only three levels and there is no music.
