How does it work?
The TNT block is replaced by a nuclear weapon which when exploded will cause a huge explosion, lots of fire and total destruction. The golden armor is replaced by a hazmat suit.
You can either ignite the block by using a flint & steel or by using redstone. Here are some examples of the type of damage the block can cause.
It’s insanely dangerous and you only got 35 seconds to escape its area of impact.
The creeper has been turned into a Nuke Creeper. The explosion is slightly larger than normally and it will also cause some fire.
