Airlock Door


 * Allows citizens to safely enter/exit your base. - In-game description

Can be toggled by the player between Normal, Locked and Forced Open.

Often used with an Airlock, which requires both an entrance Airlock Door and an exit Airlock Door.

Tips
This door can be used as an emergency fire extinguisher by first evacuating a room with an Emergency Alarm, sealing the room with some Doors, then forcing open the Airlock Door to expel the Oxygen and extinguishing the fire.

You can also use it to forcefully expel hostile entities from your station by using the same method.
