The Bunker

As the bomb sirens grow louder, can you escape from behind enemy lines? The year is 1944 and you are part of the Royal East Kent Regiment, supporting France on the swiss border. After a surprise ambush, your allied troops are scattered and imprisoned. You and the remaining survivors have retreated into an abandoned bunker in an attempt to evade enemy capture. The enemy is scouting, searching through the area, and will reach you at any moment. There is an alternative exit to the bunker but the previous occupiers have made this route nearly impossible to find, after they received warning of the incoming invasion.
