Destroy the Glaxxons with your laser rocket before they swoop down to attack you. Miss them and they rejoin the formation to attack again. One or two player game. Choose the level and speed of play. Choice of three colour screens. High speed arcade action game. Full colour graphics with sound. Machine Code. One or two joysticks required.

The object of the game is to destroy as many of the Glaxxons as you can, whilst avoiding their missiles. In each attacking formation there are four different types of spacecraft. The lower three rows fire missiles and make diving attacks on the player, whereas the top row does not dive during battle but fires smart missles instead. If you successfully destroy an entire attacking squadron, a new formation will appear to continue the challenge.

Joystick control via right joystick port. Fire will launch a laser missile (cancelling any current missile in flight).

The point multiplier advances each time an entire enemy squadron is destroyed up to the maximum level of three. A bonus ship is awarded for each 10,000 points.

The number of ships remaining along with a protective shield gauge is displayed under each player's score. Each player starts the game with three ships and the protective energy shield allows a ship to sustain three enemy hits before it is destroyed.

The demo mode is activated if you enter a game speed of zero. Pressing BREAK whilst the computer is asking for game speed or player levels will lock the game into the demo mode which can then only be cleared by pressing RESET or switching off.
