This is Llamasoft's version of Galaxians, although there are some unique features. Lines of aliens sweep around the screen and up from the ground. You shoot at them with a fairly typical spaceship while trying to avoid being rammed: the aliens attempt to steal your humanoids who stand on the ground. If they succeed, they throw their (deadly!) skills back at you. Sounds simple?

All this happens at Llamasoft's usual greased lightning speed, keeping your firing finger very busy. If you survive until the fourth wave, your ship grows an extra cannon, doubling your firepower.

Graphics and sound are excellent: but the game is incredibly difficult even for the early frames, so all but arcade freaks may soon lose interest.
