The Explosive Charge (commonly called "C4" or "Satchel Charge") is a craftable explosive weapon that can be placed on walls and doors.
It takes one C4 charge to destroy a Wood Door and two for a Metal Door when placed in the center. C4 will deal damage to anyone standing within a close proximity when it explodes.
Explosive Charges are not to be confused with Explosives!
Explosive Charges can be found as rare drops in green and Silver/YellowLoot Crates (commonly found in rad areas), and are also rarely dropped by Mutant Bears & Wolves, whereas Airdrops commonly contain up to 2 of them per crate.
