Return to Castle Wolfenstein Operation Trondheim Special Forces – the first part of the trilogy, telling about Hitler, trying to cross occultism, exact sciences and military affairs. With the help of genetically modified and mutated soldiers, he tries to conquer the planet. The player will have to fight with the soldiers of the Third Reich, gradually encounter powerful bosses and get new weapons.

The event of this part of Wolfenstein will take place near the port of Trondheim. As soon as the war began, the Nazis managed to seize control of it, where they also gained access to a radar capable of seeing any equipment within all northern waters. This gives a significant advantage in strategy. Because of this, the Allies need to recapture control of the port. The enemies have created additional fortifications, installed equipment, defensive structures and are ready to defend.

The main character carries out a secret mission alone. His task is to destroy the radar by any means necessary. On the way to achieving the goal, he will kill hundreds of opponents, get to unusual weapons, fight bosses and mutants. The success of the central character will affect the outcome of numerous events in the subsequent war. If he manages to break through the defense and reach the checkpoint, then together with his allies he can declare the goal accomplished.
