Welcom to HBM & Stuff, it is exactly as the modpack is named.

You have the HBM Nuclear Tech Mod and a few other mods that allow you to either blow your friends to smithereens, or create and decorate a very discreet facility.

The mods such as Chisel, Carpenter's Blocks, Malisis Doors, and Better Builder's Wands allow for the ability to quickly but nicely decorate any kind of base.
I've also included small mods like Slime Blocks, and More Pistons to adda more enhanced vanilla feel to this complicated modpack.
