It is the year 1942 during the second World War, right now you are in Europe during the Battle of Stalingrad. Somehow, you, an American soldier ended on this battlefield. However, the rest of the world is panicking because the male population has been destroyed. To the rest of the world all males have been extinct meaning that the extinction is inevitable, and didn't help that the war is going on.

Right now you are in a destroyed building getting shot at by German soldiers. You take cover behind a wall reloading your M3 submachine gun, panicking because a tank shot at the wall to your side leaving you VERY exposed.
