A secret headquarters of concrete and steel is the heart of Hitler’s plans for domination and the key to a Nazi conspiracy - the Wolf’s Lair.

The Bismarck and Tirpitz were battleships of record breaking proportions, ultimate status symbols of the Third Reich and hunted by the Allies.

In a quest for world domination, the Nazis built some of the biggest, deadliest pieces of military hardware and malevolent technology in history.

In retaliation for Allied bombing raids, Hitler ordered the development of the V1. The first cruise missile, it changed the face of war forever.

As America closes in on Japan in 1944, the Japanese turn to desperate new tactics: killer planes and super torpedoes guided by human pilots.

The campaign to breach Hitler's 400 mile-long Siegfried Line took more than six months and cost the American forces 140,000 casualties.
