Computers? Gaah! They're taking over the world! Well, one's taken over this world and its intentions to wards you are less than amicable. So you have to wing your way over certain key cities, shooting out the buildings before landing and dispatching the pilot to capture alien scientists and key cards.
The cards provide money for extra ammo, etc, and, more importantly, parts of the password that gets you to the next level. The graphics are great particularly on later levels, and special mention must go to Martin Galway's funky music. Gameplay is good, but it would have been better if there was more blasting and less dithering around looking for keycards.
