Nuclear weapons played a key role in the final stage of WWII, and their role in War of Supremacy has now finally become a similar one. In the past, nukes player a more powerful role as they were easier to get and raiding was weaker or (before then) non-existent.

In order to build nuclear weapons the following conditions must be met:

• The Nuclear Bomb research must be complete. (See Researches)
• The Nuclear Pact law must not have been passed. (See Debating)

Futhermore, the weapons themselves cost $150,000,000 to build and require 10 turns of production. A factory must be available with employed engineers. A turn is then placed into the production field and if $15,000,000 is used to build 10% of the weapon. At this point your territory will appear on the nuclear powers list in the rankings.

Nuke damage has varied throughout the development of the game, at present nukes destroy a percentage of everything in a territory equal to the percentage of land which the nuke has destroyed. The exception of this is military units which suffer double losses. Land damage varies between 800 and 1000 kms.
