First of all, it is very complicated to develop to the nuclear weapons stage, and it is also the ultimate technology of the game. Players need to do atomic research first (1940), then reactors (1943), and finally nuclear weapons (1945). However, the production process of nuclear weapons is very slow, and only by building more reactors can production be accelerated.
After the production is completed, the player must make bombers and air superiority to release nuclear weapons, and then destroy all the buildings and units of the other side.
