A disappointing version of Space Invaders. You move a laser base left and right across the bottom as rows of aliens drop bombs. At intervals a mothership zooms across the top, sometimes launching an extremely speedy bomb.

The instructions on the insert warn that the aliens must be hit dead-centre if they are to be killed. In the trade, this is known as calling a bug a feature. In fact, your shots sometimes go right through the middle of a column without claiming a life. At other times, a shot which completely misses will nonetheless kill an invader! Enemy bombs are dropped directly on your base, and you can't shoot them down.

The display is dull, with a yellow base and green aliens on a blue background. The enemies change colour as they near the bottom. Curiously, explosions are in black and white. Sound is reasonable.

Continental Raiders seems to have been a rush job - even the name Continental Software is mis-spelled on the title page, where the same is called Cosmic Raiders. If Memotech must revive old game ideas there's really no excuse for doing it this sloppily.
