Minefield was written in 1983 for the ZX81 by Stan Hatton.

Your mission is of the suicide variety and of the utmost importance - vital to the war effort in the war you have happened on. And that is why to a certain degree your lives are expendable. You command three men and their task is to beat a path through the minefield - at least one of your men must get through as three explosions will alert the enemy that someone is trying to cross their defences and your mission will be over. You move your men across using the cursor keys. No clues or hints are given as to where the mines have been hidden - you must manoeuver your men purely on instinct. Good luck!
