You are The Extirpator, remover of unwanted items by force. Your task is to root out all evil from the universe and to help you do this you have been placed in charge of the Eagle X-Ray squadron. Your latest mission is to lead a counter attack against the forces of Lax IV who have invaded and enslaved your home planet.
You must lead your nine vessels through a number of sectors which are patrolled by enemy pods and craft. After negotiating one level you have to blow your way through the sector wall to proceed to the next sector.
Loading is easy. Remove all cartridges from older machines and hold down the Start key while switching on. On newer machines you have to hold the Start and Option keys while switching on. Then press Return and the game will load.
You control your ship using a joystick plugged into port one - I found the joystick response a little sluggish.
At the top of the screen you will find a very colourful status line which indicates your score, lives remaining, power and what game level you are on. The main screen scrolls from left to right. By splitting the screen into four parts and moving them at different speeds, the programmer has given the game a feeling of depth.
The design of your ship is original, and so are the enemy craft - one of them reminded me of a flying whale.
I found the graphics quite presentable and the sound effects rather good. The title music is a superb, jazzy piece and really got my foot tapping.
