Evictor

Evictor is a 1-player arcade game for the Dragon 32/64.

The player's task is to destroy an alien base which has an atomic reactor that regenerates energy blocks as a protective shield. The base is defended by two pairs of guns and alien spaceships that appear and vanish randomly. The player controls a flying saucer which automatically flies back and forth over the alien base.

The player is armed with phasers that can destroy yellow alien space ships, lasers that destroy green alien space ships and force fields, and bombs that disable enemy guns, enemy blocks, or destroy the base.

The ship starts with 100 percent energy, which is decreased by movement, firing weapons, or hit by alien fire. When energy reaches zero, the player's ship must land to refuel while the enemy regenerates. There are a total five difficulty levels. Final score is based upon how many shots are required to defeat the enemy.
