In an alternate version of the 21st century, the Germans have taken over the world after winning World War II. The player is a scientist in the future and, with the help of a time machine, they travel back to the war to alter the outcome and find out how the Nazis managed to win it in the first place.
In this first-person shooter, the player encounters Hitler's SS troops and Wehrmacht infantry equipped with pistols, machine guns, bazookas, and more eccentric weapons in locations such as castles and ruined cities. Using the time machine, players also travel back to see the impact of their actions, such as with modern scenery and weapons. Vehicles, planes, and submarines are active game elements in a 3D world powered by Calaris' IC engine.
The game has lots of explicit violence and includes Nazi symbols, and German voice acting.
