Atomprojekt contains 34 levels that closely follow the style of the original Wolfenstein 3D and Spear of Destiny missions. All levels have been balanced for pistol start or continuous play. There are also three secret levels for you to discover, the last of which is especially well hidden.
It's 1943 and the darkest days of the Second World War are raging. Intelligence reports that Nazi nuclear physicist Dr. Josef B. Engelke has successfully split the atom and is in the process of building a weapon for Hitler capable of destroying London.
You, B.J. Blackzowitz, the Allies' top spy, have been chosen for this mission.
Engelke's laboratory is at a currently unknown location. Known as Atomprojekt, the nuclear project is being funded by Hitler and managed from the military installation at Erlangen. Go to Erlangen and discover the location of Engelke's research facility. Then, you must go to the laboratory, assassinate him, and destroy his research. Be quick, as it is not known how close Engelke is to having a usable weapon.
