This game is similar to a number of arcade games - Galactic Invaders and Firebird to name but two.

You fight your way through sectors of space using a laser cannon which appears at the bottom of the screen. This has lateral movement controlled with the arrow keys and fires a laser cannon by hitting the space bar.

The invaders do not take on the orderly progression down the screen of earlier invader games, but swoop at you in a haphazard way. The last three aliens in any screen take a very determined approach to destroying you.

The only further control you have over your ship is entering hyperwarp. This is achieved by pressing any of the numbered keys and this advances you to the next sector which contains more powerful aliens.

The graphics of this game are up to TRS-80 standard and the program has sound capability. A record of your score is shown, as is the number of ships that you have remaining.
