Blastcraft intends to protect against the destructive forces in the ICBM mod. Each block available in Blastcraft can withstand a direct hit from a Missile. It is useful in the field of construction of missile-proof buildings, i.e. bunkers and military bases. Not only does it protect you against your enemies, but it also protects your home against the likes of test explosions or nuclear reactors.
This project is based upon Electrodynamics and requires this mod to run. Therefore you have to install both of them for this mod to work.
