Laser Blast

The object of Laser Blast is to destroy a series of land-based enemies. The player controls a fleet of flying saucers, operating one at a time. On the planet surface below are a group of three mobile laser bases, guarded by an invisible force field that prevents the player's saucer from getting too close to the surface. Both the player and the enemy bases are armed with laser blasters, which may fire a single continuous beam at a time. The player must destroy all three bases before they are able to target the saucer and fire their own laser blasts in defense. If the player's saucer is hit, it will lose altitude and crash to the ground; however, the player may direct this fall, potentially into one of the bases, destroying it as well. Each succeeding wave of enemy bases moves faster and targets the player's saucers more quickly, while the force field becomes stronger and decreases the amount of space in which the saucer can move.
