The discovery of a planned alien invasion of Earth has put an end to petty East-West squabbles, and pilots from both sides of the Iron Curtain are involved in Operation Sanxion. As one of these pilots you must patrol your ten horizontally-scrolling zones, destroying any alien infiltrators.
Sanxion was Stavros Fasoulas' debut game which wowed the team back in November 1986 with its amazing parallax scrolling, superb sound and startlingly addictive gameplay. It was given an overall mark of 93%.
Even now, shoot-'em-ups of this quality are few and far between, so as a budget game it's well worth a shufty.
