The Reidite Door is the highest tier of doors, which enable players to toggle them to be opened or closed. Only the person that placed the door and teammates can use it.
Doors can be costly. However, it's a necessary precaution for defense when making a base. Doors can enable players to protect chests, separate compounds, or layer for additional fortification.
Having multiple doors in a base can help as they enable players to enter and exit the base with convenience.
Any amethyst tool or hammer can break the reidite door if used long enough.
