Two spaceships enter, one leaves. The presentation on this disk version masks what is a very simple game.
Having selected a ship and number of players (one vs. one, or vs. the computer), one of four backgrounds is loaded in. One player must eliminate all the opponents to win, whereas two players play to the best of five rounds. In the tiny playing area, the two (nicely drawn) ships shoot at each other to deplete the opponent's energy.
The computer skill level is not bad as it tries to dodge, but it soon becomes very boring.
