Guardian

The year is 2112, and the high priests of the Solar Federation have entrusted you with the sacred Emerald of Syrinx. As the Emerald's Guardian, you must keep the stone safe from the various enemies of the universe who would kill you for it.

The player must escape a series of rooms, in order to keep the Emerald safe. The player can move in 8 individual directions using the keyboard, as well as fire in 8 separate directions. The player starts at the center of each room surrounded by enemies, who will after several seconds begin to move towards the player. As the player shoots enemies, an exit will appear in one of the four corners of the stage. When a creature is shot, the exit moves to a different corner. The player must move to the exit within the allotted time. The player must complete a set number of rooms to win the game, and as the player progresses, the allotted time is reduced. In later rooms, walls will become deadly, and on the highest levels, will disappear after several seconds.

The game offers Normal and Expert play. The player starts with 3 lives, and if all are lost, then it's game over.
