1. What about a salvaged hammer that can beat doors?
    I thought about the following properties:
    - Each blow costs 'x' explosive from the inventory (configurable value)
    - Different chance to beat a door and destroy the lock/codelock. Only destroy the lock and open the door, dont deal damage or destroy the door. (Chance: wood: 50%, metal: 15%, armored: 5%) (configurable value)
    - each hit adds damage to the attacker (configurable value)
    - deal extra damage to stone structures (configurable value)
    - Explosion effect
     
  2. sounds like a lag Fest but cool idea.
