My first thought when I saw the cassette was that I was going to review a detective adventure game. How wrong I was! It is another multi-level game in which you move up and down ladders and along platforms. There are trapdoors, chutes, escalators and lifts.
Small men with guns walk about the screen and shoot at you. You may either shoot them or dodge the bullets by using the ladders and chutes or by crouching down.
The screen displays one part of a cross section of a tower block at a time. As you move the display scrolls to show more of the playing area. The graphics are quite good.
A full score table is included which tells you your current status, etc. You may save the game halfway through and continue at a later date.
Finally, I was not impressed by the one bug that I found in the game. Sometimes when you go down a chute, the game goes into an endless loop, displaying various title screens which change as you press the fire button.
