Bridge on the Rhine The Panzer divisions are rolling in a last-ditch attempt to halt the Allied advance. Your job is to guard a bridge and try to take out as many tanks as possible with your limited supply of ammunition. Use keys Z and X to move the gun and P to fire. The game increases in difficulty as you progress, and penalty points are deducted for every tank that gets through. The game was written by William Johnson of Faversham in Kent for the 48K Spectrum.
