This is a side-scrolling space shooter. In 1988, this game was released for the Atari 8-bit under the Firebird label. This Supervision version came out in 1992, published by Silverbird Software.
Firebird was a label under the company Telecomsoft. Apparently, starting in 1988, they added the Silverbird label for their budget games, while full-price releases got the Firebird label.
