(EDIT - Just a note, if you grabbed this mod before 2/1/2017, and are still in the first 7-8 levels, you may want to consider re-downloading it. It is not necessary, however, as no changes involved anything that was game-breaking. If you are on Floor 8 or later already, there is no need to consider another download.)
After almost a half a year of continuous development, Barry Christian has released his long-anticipated mod Atomprojekt. In this mod, BJ's objective is to stop the Nazi's nuclear physicist, Dr. Josef B. Engelke, in his attempt to develop a deadly nuclear weapon capable of destroying London. You must get to his laboratory and stop the doctor in his tracks! The location of Engelke's lab is currently unknown and the project is being managed from the military installation at castle Erlangen. You must first go to Erlangen, uncover the location of the lab, and then get to the lab and kill him. Be quick, because it isn't known how far he is from having a usable weapon!
Atomprojekt contains 34 consecutive levels which span multiple themes but mostly stay true to the flavor of the original Wolf3D and Spear of Destiny games. Every level has been specifically balanced to be playable both on pistol start AND continuous. There is also a variety of other new features: new 'Read This!' and intermission screens, graphics, enemies, sounds, and even some new music tracks, all while staying true to the spirit of the original games. And a handful of other surprises which, of course, I'm not going to reveal here!
Look carefully too, for there are three additional secret levels to discover - the last of which finding may prove particularly tricky.
