Gravity

Gravity is a shareware, single-player, space shooter that is keyboard or joystick controlled.

The game starts with the player piloting a space ship through a maze inside an asteroid within which are aliens. The aliens are not friendly and not only do they have canon in the maze they also have attack ships. The asteroid has a gentle gravity which means the ship will always fall down the screen unless thrust is applied counter it. However this is space and once the craft is in motion it will continue to move and its path will not change unless it is rotated and a counter thrust is applied. Later levels take place inside the infested planetoids, space ships, and even Earth. Once a level is completed the payer is given a password which enables them to restart at that level when they resume the game.

The object of the game is to negotiate the maze, kill the aliens and collect the power ups before the timer runs out.
