You can choose up to 8 different nuclear bombs including an asteroid impact. The power of the explosion ranges from the one used in Hiroshima in 1945 during World War 2 – the 15 KiloTon “Little Boy” to the most powerful explosion in history – the 50 MegaTon “Tsar bomb”, a Hydrogen fission bomb tested by USSR during 1961.
The following simulation shows what will have happened if “Little Boy” was detonated over New York.
