Gravitar was the first of over twenty games Mike Hally designed and produced for Atari, including Star Wars.
Unlike many other shooting games, gravity plays a fair part in Gravitar: the ship will be pulled slowly to
the deadly star in the overworld, and downward in the side-view levels.
The player has five buttons: two to rotate the ship left or right, one to shoot, one to activate the thruster,
and one for a tractor beam on a planet, or a force field in the overworld.
In the side-view levels, the player has to destroy red bunkers that shoot constantly, and can also use the
tractor beam to pick up blue fuel tanks. Once all of the bunkers are destroyed, the planet will blow up, and
the player will earn a bonus. Once all planets are destroyed, the player will move onto another solar system.
The player will lose a life if he crashes into the terrain or gets hit by an enemy's shot, and the game will
end immediately if fuel runs out. For the main part, Gravitar wasn't very popular.
