Metal Doors were a craftable item in Legacy. They were primarily used to restrict the passage of unknown players into a building while allowing the creator (and other authorized players), free access. It was the second tier of doors, after Wood Doors, and was the strongest door in the game. It did not take melee damage. However, the door could be destroyed with 16 F1 Grenades, or 3 Explosive Charges (usually taking two due to Decay).
