The Last Armoured Train

World War 2, in the early stages of Operation Barbarossa, the Third Reich created a special force called "Brandenburger". The mission of this particular unit is to size river bridges behind the soviet lines, before the retreating Soviet Army can destroy them. However, a Russian armored train in their sector remains to keep a thorn in their side. When the whole Russian front line seems to collapse in the eve of the fascist juggernaut, this Armored Train must be eliminated at all costs.
