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.
