The cartridges that squeeze into the back of the Vic are actually quite small. It is strange however that some are packed full of crazy mutants and hideous aliens, while some have barely enough horrible denizens of outer space to invade a reasonably-sized chocolate biscuit. Gorf is in the former category.
In four stages they come, first as space invaders, then armed with lasers, then swooping and spiraling out of what we are told is a black hole (who can doubt it?) and finally shuttling around in a large rocket while bombarding us hapless earthlets with chunks of asteroid.
This is a very good game, well thought out and carefully presented. As you struggle through the stages, you are promoted from cadet upwards, and as the Russians discovered at Stalingrad, promotion and the honours of elevated rank motivate fighters to battle with will.
Herein lies a problem... A person of my acquaintance *fractured his joystick* while playing this game. What a fate! Let this be a warning to you all. Waggle it around but don't grip it too tightly or you might break it off...
