Boris is a funny-looking fellow, who has had his home raided by creatures of the underworld. They
steal most of his possessions, and the unforgiving Boris decides to venture underground himself
in the hope of retrieving his valuables.
Boris can move in four directions and has a rapid-fire, laser cannon. A joystick can be
used with the game, which in my view aids play. As soon as the game starts, the underworld creatures
start rushing towards you, and you must start firing straight away. This is nothing like a
"shoot 'em out of the sky" game but, nevertheless, the creatures move like those in the
legendary Space Invaders. The sound is identical and the more you shoot, the harder it is to
outrun them. When you have finished them all off, one of Boris's possessions appears on the
screen.
In the later stages, indestructible discs start appearing on the screen. This considerably slows
down the process of killing the undergrounders. These and the fiery walls which close in around
you make the game almost impossible.
