In a world turned upside down and back to front, the Baddies are back again as Seiddab. We first encountered them in the deepest reaches of space, alone in our attack craft in 3D Space Wars. Now the Seiddab have landed on earth and are attacking the cities at night.
You are in control of a 'Drone' - a sort of remote control modern tank, patrolling the streets on the look out for the Seiddab space ship in your sector. The screen display shows a 'cockpit' view through the front of your tank, the details of its armour plated front and hatches before you. Beyond that, the darkened city streets stretch out in perspective, the sides lined by glass tower blocks ablaze with- myriad lights, their inhabitants evidently happily unaware of the nightmare taking place outside.
Below the cockpit view there is a local A to Z street finder - a radar which shows the city blocks, streets and the enemy fliers as well as your own position. This radar actually wraps around top to bottom and left to right, and so is theoretically infinite. To its left are your three drones (lives) and the status of your man. To the right are the scores for players one and two and the hi-score.
The object of the game is to destroy at least ten Seiddab (on the first screen - more later) at which time your radar will detect the Task Force Leader and identify him by a trail left on the radar. To clear the screen you must destroy him whereupon the action switches to the countryside.
