The German war industry is in desperate need of more iron ore. Hitler turns his attention to the Norwegian coast, and in particular the port of Narvik, through which iron ore mined in Sweden is transported. The British Winston Churchill also makes his own plans to invade the Norwegian coast.

After the First World War, Europe is divided. The alliance between Germany and the Soviet Union, Hitler and Stalin triggers the Second World War. At the same time, the Arctic War begins, with Finland as the first theater.

There is deep mistrust between the two sides and the Cold War becomes volatile. The Soviet Union threatens NATO with a neutron bomb and actively exercises in its border areas. NATO deploys more missiles in Europe and organises a massive military exercise. Soviet submarines invade Swedish and Finnish waters. Sweden increases its readiness in the north and Norway builds bunkers. Finland strengthens its air force and control of Lapland. A Soviet missile strays into Finland. In the end, nuclear war was just a push of a button away.

The East and the West are failing in their attempts to limit the threat posed by nuclear weapons. The Soviet Union increases missile activity on the Kola Peninsula. The United States builds an extensive nuclear weapons network under ice and prepares for a Soviet attack with a plan to drop thousands of nuclear weapons. The Nordic countries are also on the list of nuclear targets. The superpower race is wreaking havoc in the Arctic and claiming lives in space. Finland is under pressure to cooperate militarily and President Kekkonen's role is being questioned abroad. Norway tries to mend relations with the Soviet Union.

The Allies are planning the invasion of Normandy and are preparing a major deception operation in the north. Commando raids continue and resistance movement increases. Hitler continues his massive building projects in Norway, despite the threatening situation. He intends to hold on to the iron ore transports and the Petsamo nickel mine until the end.

The Germans launch a retreat of thousands of kilometers on the eve of the Arctic winter. The Soviets launch a major offensive in the north while the Finns press the Germans into the massive Sturmbock defensive line.

The United States and the Soviet Union worked closely together during World War II to defeat Hitler's Germany. However, the Allied standoff and ruthless competition for Nazi weapons technology began behind the scenes even before the end of the war and escalated rapidly. The superpowers are also seeking a stronger foothold in the Arctic.

Hitler decides to take a risk and invades the Soviet Union. In the north, the aim is to seize the Petsamo mine, the port of Murmansk and the Murmansk railway. Finland enters the war alongside Germany.
