How do you get Nuclear fusion in Powder toy?
@Quartich They used a modified, I don't remember, I think it was a TU95 bomber. It was painted white to reflect the thermal radiation. Just off the top of my head. Yes, it is a thermonuclear bomb, opposed to a nuclear bomb. Not off Wikipedia, Honest!
the tsar was nuclear not atomic i used nuclear fusion this uses fission
so here's what I know on it: it was made by Soviets during the Cold War they had designs for 100 megaton version but were to scared to use it due to a possibility of a nuclear fallout so they made a 50 megaton version that they tested but is unconventional because no plane of the times existence could carry it.
