Cylon Attack

Cylon Attack is a 1-player arcade game for the BBC Micro.

The player controls a spaceship that moves laterally along the bottom of the screen and shoots a large laser that instantly reaches the top of the screen when fired. A line of alien ships appear at the top of the screen while, one at a time, they drop towards the bottom while firing. The player gains points upon destroying an alien vessel, but loses points if the ship reaches the bottom of the screen. Ships reaching the bottom then appear again at the top. When all ships are destroyed the player enters a new stage, where every three stages the enemy ship color changes. The player starts with five lives.
