LEVEL 0: Standard operating personnel. Personnel at this level are not permitted any contact with an SCP object; breach of this protocol will result in termination of the personnel involved.Edit
LEVEL 1: Standard security clearance level for staff involved in the maintenance of an SCP object. Level 1 clearance is usually appended with the SCP object the personnel have clearance for (e.g. 1/173).Edit
LEVEL 2: Clearance level for staff involved in overseeing an SCP object. Appended with the SCP object the personnel have clearance for, separated by a dash for those with clearance for multiple SCP objects (e.g. 2/173-847-423).Edit
LEVEL 3: All general security staff for Site-19 or any other site housing an SCP object are required to have this level of clearance and are permitted access to all non-Keter level SCP objects.Edit
LEVEL 4: Command-level personnel; permitted access to all non-Keter level SCP objects.Edit
LEVEL 5: Highest ranking Senior Staff; most personnel at this clearance level are Overseers. Certain members of Senior Staff have been given Level 5 clearance due to repeated need to work on Keter level SCP objects.Edit
The keycards are craftable items. They are very useful in LAN mode and in custom maps. If a door is secured with a (for example) level 2 keycard slot, to open it the player must use a level 2 or higher keycard.
