Rust’s Large Oil Rig, introduced in the 2019 QoL Update, is a high-stakes monument floating in the ocean, offering elite-tier loot for those who conquer its challenges.
This multi-level rig hosts up to 35 scientists, 23 standard, 12 heavies, guarding 31+ crates filled with weapons, components, and meds.
No radiation simplifies gear, but its isolated location demands boats or helicopters, keycards for puzzles, and ammo for firefights. With 2024’s Moonpool entry, solos and squads can tackle it efficiently.
This guide covers preparation, approach, clearing, puzzles, and extraction to master the rig in 2025’s meta.

Preparation: Gear for the Fight
Raiding the Large Oil Rig takes 30–60 minutes and burns 500+ rounds, meds, and resources. Transport is critical: Rowboats or RHIBs for stealthy solos, Minicopters for fast drops, or scrap helis for groups. Fuel up to avoid being stranded mid-ocean.
Essential Loadout:
Budget 1k–2k scrap equivalents. Practice on aim servers like HungryAim’s Oil Rig mode to master scientist kiting. Time runs for low-pop hours to avoid Zerg counters.
Getting There: Approach and Entry
The rig spawns on the map’s ocean edge, identifiable by its towering structure. Chinook patrols signal activity, so scout with binoculars before committing.
Entry Methods:
Hide your transport to deter boat-jackers. Footsteps echo on metal decks, so move cautiously to avoid alerting scientists or raiders.
Clearing the Rig: Level-by-Level Strategy
The rig’s seven levels (L0–L6) hold 31 crates, with scientists respawning every 24 minutes. Clear methodically: peek corners, kite with grenades, loot corpses for cloth/ammo. Heavies (flamethrowers, heavies) drop premium scrap—prioritize headshots.
Level Breakdown:
Solos need 45–60 minutes; duos+ cut it to 20–30. Check CCTV mid-run for counter-raider intel.
Puzzles and Locked Crate: Unlocking the Loot
Puzzles require only keycards and no fuses. Three rooms yield tier-2/3 loot, with the locked crate as the jackpot.
Puzzle Steps:
Puzzles respawn cards for looping. Expect 200–500 scrap, weapons (Thompson, AR), meds, and components.
Extraction and Tips: Survive with the Spoils
Escape via heli (steal if spawned) or boat. Jump off edges into water to avoid fall damage. Counters often lurk, so hold stairs or use ball traps at chokepoints. Stash loot in barrels if overwhelmed.
Pro Tips:
Conclusion
The Large Oil Rig is Rust’s ultimate risk-reward test. Nail it, and you’re set for the wipe. Fail? Regroup and retry. May your crates be bountiful, survivor.
