In 1942, Hitler wants revenge for the relentless bombing of German cities; in a secret research facility, his scientists are developing the world's first cruise and ballistic missiles.

In 1945, Stalin wages a war of annihilation against Nazi Germany; over one million Soviet soldiers charge towards Berlin; the Red Army must defeat several German strongholds in a series of battles.

By 1943 Hitler's marauding armies have steamrollered across mainland Europe; the allies can't compete on the battlefield, so the commanders plan an audacious attack on the booming industry, which is producing German tanks, submarines and aircraft.

December 1944 - Hitler launches an all-out assault on the Western front across Belgium and Luxembourg; vastly outnumbered allied platoons face off against entire German battalions in a series of David Vs Goliath attacks.

In May 1940, 400,000 Allied troops are surrounded by Hitler's army on the beaches of Dunkirk; deep in the tunnels under Dover Castle, the Royal Navy plans a rescue mission; success or failure could decide the outcome of the war.

Reconstructing the WWII battle in the skies over Britain, the hunt for the deadly Nazi U-boats, the parachute drop at Arnhem, the Allies' bloody struggle through Normandy, the showdown at the Italian Abbey of Montecassino, and the fight for Poland.

The longest campaign of the war pits the deadly stealth of the Nazi U-boats against the code-breaking genius and long-range bombers of the Allies.
