Skeleton Key


The Skeleton Key mod adds three new items (SCP, documentation and label) and one structure to the game.
The mod is heavily inspired by SCP-005 from the SCP Foundation Universe.

SCP-005 is an anomalous ornate key capable of opening any lock.
In this mod, SCP-005 can unlock any physical or digital lock, making it one of the most powerful and mysterious items you can obtain.

SCP-005 can be placed by Shift + right-clicking on a block.  
Right-clicking on a door/trapdoor/gate with SCP-005 will open it. It cannot close doors; in canon with the SCP Universe, it only opens locks.
