The Nuke Addon turns the TNT block into a highly destructive nuclear weapon. It’s not something to play around with but it’s definitely useful if you want to add some changes to the terrain around you. It’s not really comparable with a nuclear weapon in real life but it’s definitely dangerous.
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 1 minute after it has been ignited to escape its area of impact.
