- Stacked card rooms + locked crate event
Large Oil Rig is the whole keycard chain compressed onto one offshore platform: a green room that pays a blue card, a blue room that pays elites, and a red room holding the game’s richest locked crate event.
Why you’re here
Everything at once. Large Rig is the only monument where all three card tiers cash out in one trip — and its locked crate event escalates past Small Rig’s, with eight heavy scientists riding the Chinook in. Crews treat a full Large Rig take as one of the best paydays in Rust.
The layout
A towering multi-deck platform. The green puzzle sits on Level 3 (fuse-box door, no fuse needed — rigs power themselves), the blue room adjacent, and the red room up on Level 6 inside the white admin building under the helipad. Scientists garrison every deck and the ladders between them.

Loot worth the trip
