Demolator is the best game yet to roll off the production line at Visions Software Factory.
You control a droid in a scrolling maze full of nasties. The action takes place aboard the BS Quinn Battlestar which is transporting the last survivors of an attack on Earth to safety across the other side of the galaxy.
The Demolators have penetrated the ship's defences and are exterminating its human cargo. Your robot is armed with a laser gun with which he must blast the aliens.
Three types of nasty must be dealt with in the game's 24 levels. Easiest of these are the Minors, who must be blasted before they turn into stationary, though deadly, mines.
Slightly tougher are the Protectors who move around and whizz bullets at you. Toughest of all are the Trackors who home in on your droid with deadly precision.
Also dotted around the ship's maze-like structure are several fuel dumps which you have to touch for bonus points.
I enjoyed this game. It's not terribly original - combining elements of Berzerk with a standard shoot-'em-up - but it is surprisingly addictive and well executed, with good speed and graphics.
