For those of you with shorter memories than mine, Sacred Armour of Antiriad was the first ever game to feature interactive-comic-o-vision. What that means is that you get a free 16-page comic book with the game, telling the story of the sacred armour tells you that you have to clean the earth of the evil mutant scum by destroying a huge radioactive plant. To do this, you have to find the armour itself, along with a power pack, some jet boots to get it off the ground, a laser for defence and the super bomb to wipe out the tower.
This is a big adventure with more of the emphasis on arcade. The graphics are large and very detailed, the animation is ultra smooth and the game itself is very, very playable. You probably have got this already, but if by some strange quirk of fate, you don't, then get it. As Major Tom in CU would say, it's brill kids.
