Two-card blue puzzle with patrolling scientists, hangar loot and a T1 workbench.
Mid-game puzzle monuments. Most need a green card → blue card progression and one fuse. Loot tier rises sharply (military crates, elite crates, components, scrap) — the meat of the monument economy.
| Keycards | 1× Green + 1× Blue |
|---|---|
| Fuses required | 2 |
| Scientists / NPCs | 5-7 (patrolling) |
| Radiation | Medium |
| Recycler | Yes |
| Workbench | Tier 1 |
Airfield is the most-iconic Tier 2 puzzle monument — a sprawling military airstrip with patrolling scientists, two-card puzzle progression (green → blue), two fuses required, and a Tier 1 workbench inside the locked hangar. Loot ceiling is significantly higher than green-card monuments, but the scientist defenders make it a meaningful combat encounter. Five to seven heavy patrolling scientists means hazmat and a rifle are recommended.
Airfield's puzzle has multiple stages:
5-7 patrolling scientist NPCs guard Airfield. They use SMGs and rifles, deal moderate damage, and have decent accuracy at medium range. To clear safely:
Both a green keycard and a blue keycard, plus two electrical fuses — typical Tier 2 progression.
Five to seven heavy patrolling scientists. They deal moderate damage with SMGs and rifles, and respawn over time. Hazmat clothing and a Tier 2 rifle are recommended.
Tier 1 — useful for crafting items that require T1 access without owning your own. The Tier 2 workbench is at Bandit Camp, Outpost, Launch Site and Military Tunnels.
Yes if you're prepared — bring a Tier 2 rifle, scientist-killing experience, and hazmat. The loot ceiling is higher than any green-card monument and the workbench access is a bonus. Solo runs are tighter than duo or trio runs but doable.
On the inner hangar wall, after the first green-card door. Many players arrive with one fuse and have to leave to find a second — bring two from the start.
Medium-tier radiation — basic clothing isn't enough. Bring at least road-sign / scientist suit pieces, ideally full hazmat.
Airfield is the gateway monument for most Rust players' wipe progression. Once you've completed the green-card puzzle circuit (Dome, Small Harbor, Satellite Dish), Airfield is the natural next step — a meaningful combat encounter combined with significantly higher loot density and your first taste of monument-defending scientist NPCs.
The Tier 1 workbench access is a quietly significant feature. Most solo and small-group bases never own a T1 workbench themselves (the cost is non-trivial early wipe), so Airfield's free T1 access makes it a high-frequency stop even after the puzzle has been cleared. Mid-wipe Airfield runs are often workbench-driven rather than loot-driven.
Airfield's scientist NPCs are the first significant PvE encounter many players have in Rust. The patrolling pattern is predictable — they stick to the airstrip and hangar interiors — but their damage scales with proximity. Engage at range when possible, use hangar walls for cover, and don't try to fight more than one at a time in the open.
