Underwater Lab B

5 loot spawners placing 4 container types.

Puzzle

The puzzle resets 30 minutes after the last player leaves.

Rust assembles this monument from modules at runtime. The captured data below does not describe every server layout or all of its loot.

What to know

  • Check the actual generated layout

    Underwater Labs are assembled from modules. Their in-game floor map and CCTV help you plan a route; one extracted module cannot prove the card requirements for every generated lab.
