On Her Majesty's Behalf

At the tail end of 1917 the Germans introduced a new type of gas to the battlefield, T-Leiche, or `corpse gas', which changed the face of the war. Rather than affect the living, it resurrects the bodies of the dead, giving the enemy an almost unlimited source of fresh troops. After surviving the killing fields of France, Burke and his men are sent into the devastated, zombie-infested city of London to rescue Princess Veronica, the sole surviving member of the royal family. However, Kaiser Richthofen, the undead Red Baron and now leader of Germany, learns of her survival.
