The S-Nav is an equippable item in SCP - Containment Breach. The S-Nav is used for navigation, each individual square represents a room. There are 3 different variations of the S-Nav.
The default version of the S-Nav, the S-Nav 300 will need a 9V battery in order to function. S-Nav 300s can be found scattered throughout the facility, in offices, SCP-106's containment chamber, the small control rooms, server rooms, and sometimes hallways. Any rooms that have not been visited yet will remain hidden on the S-Nav 300.
By putting the S-Nav through SCP-914 on the "Fine" setting, the player can now view the entire map without exploring the area first. The S-Nav 310 is capable of informing the player where to go and which paths are dead ends. S-Nav 310s, however, still need batteries.
The S-Nav Ultimate retains all the properties of the S-Nav 310, however, it will no longer require batteries and can now detect every nearby SCPs in the vicinity, including SCP-049, SCP-096, SCP-173, SCP-106, SCP-895 and all the other ones. The S-Nav Ultimate can be obtained by putting the S-Nav 300 through SCP-914 on the "Very Fine" setting, or the S-Nav 310 on the "Fine" setting.
A small red ring and the name of an SCP will appear on the S-Nav Ultimate's screen if they are nearby. The smaller the ring is, the closer to the player it is. It is able to detect multiple SCPs in an area.
- When near SCP-895's containment, the S-Nav will begin to scramble. When inside its room, the S-Nav will become severely scrambled. Despite this, the S-Nav Ultimate can still detect SCP-895's presence.
- When any S-Nav is put through SCP-914 on the "1:1" setting, the "S-Nav Navigator" will be produced, which is identical in functionality to the S-Nav-300, but is displayed in red.
- There was a crustacean in v0.7.4 where attempting to use the S-Nav Ultimate would cause a memory access violation.
