When held, it displays the time it'll take before the next event by minutes, the Biome you are currently in, and any randomly (or event-specific) Location. It serves no other purpose aside from displaying information.
All the locations can be seen here.
- In The Backwalls, the GPS turns into a glitchy mess, unreadable and useless to the player.
- If someone forces an event, the "Next event in (1-4)m" section of the GPS display will say "Next event in -9996m".
- If the GPS is held above the 5,000 stud limit, it'll always display "NO SIGNAL".
