The Sega CD (Mega CD) add-on for the Sega Genesis (Mega Drive) is often criticized for it's crappy FMV games, half-assed Genesis ports, and is even credited for the demise of Sega's hardware business. But to me, the Sega CD will always be a highly underrated system, with a library filled with hidden gems. And one of those gems is Android Assault: The Revenge of the Bari-Arm, a terrific Shmup released in 1994.
