The ID Card is an essential item that can be used in Barotrauma.
There are three different types of ID Cards:
Normal ID Card
The Normal ID Card is the standard Card possessed by any active crew members of the Submarine. There are two variants: Personal and Default.
Personal ID Card
Whenever a character spawns, they are given a Personal ID Card by default, which has detailed information on themselves and their role. Depending on the job the character has, they will be given one with a unique clearance level specific to that job. The Card is primarily used for opening doors on the submarine which are inaccessible without proper clearance.
The captain has superior access to the rest of the jobs, and is capable of accessing any rooms, excluding the private cabins of the other crew members. It is however possible to steal the captain's ID card from them when they are dead or unconscious.
Default ID Card
The Default ID Card that does not specify the owner and its clearance level is only found inside any Cabinets of a shipwreck. Its clearance level is random and more limited than the one with specific details, only capable of gaining access to certain types of hulls.
Shipwreck ID Card
|Shipwreck ID Card|
The Shipwreck ID Card is only useful when exploring a shipwreck from which it is found. It works exactly like how a normal Personal ID Card would, giving the user appropriate access to most parts of the wreck depending on the original owner's profession.
It can only be obtained from a deceased member of the shipwreck.
