Red Cross In this game you have to drive a small, light blue, armoured "Scorpion" vehicle around a battlefield. The battle is over and you have to make your way to all of the wounded, each one being marked with a Red Cross flag. Your task is endangered by mines planted in the field. Invisible to the naked eye, they can only be detected by the mine detector fitted underneath your vehicle. Every square that you move out of is given a colour to indicate the proximity of mines. Blue is safe, danger increases through red, magenta, green, cyan, yellow to white. You must trace a path around the battlefield, visiting each of the red crosses in any order, without getting yourself blown up. Time, however, is not on your side - people are dying - and it ticks away every time you move, so try to trace your path with the minimum number of moves.
