Unlike Planetters, this game is a vertical rather than side-scrolling shooter. Controls are similar to the other game, X to shoot, numpad to move, but in this case there are no super bombs, and Z selects your upgrade, in a system that's a strange hybrid of the Gradius power-up system (i.e. collect P's to purchase stuff) and standard weapon pick-ups. You buy defensive items, and just pick up weapons upgrades.

You have three ships and die in a single hit (without purchased shields) losing all your power-ups when that happens. Respawn is right in the middle of the screen without reset, meaning it can be quite difficult to recover from a death. You can pause this game with Escape.
