Clone of the vector arcade game Gravitar, where the player must enter planets to destroy all bunkers and dispose of all fuel tanks and humans (preferably by beaming the latter two up, rather than shooting them). Planets will then self-destruct, except for the reactor planet, which the player has 99 time units to navigate their way through a brief maze, shoot the reactor, and then escape before the planet explodes.
There is also an arcade version of the game (which is the same except the player's ship's thrust is more sensitive), a re-write of Patriots (Missile Command clone), and a bonus hidden game as well.
