Explosives+

The damaged cause by a 'Mega Nuke'

Explosives+ is a Minecraft mod that adds many more explosives to the game. These include C4, Nukes, Hydrogen Bombs and Nova Bombs. It also adds other cool weapons like an elephant gun which destroys large sections of the landscape very quickly, a predator missile that you can call in from above and you can even mark a point for a stealth bomber to come in and destroy. This is an amazing and very thorough mod, and is definitely a recommended download.
