Where to Find Rusted Shut Medical Kit in ARC Raiders
Rusted Shut Medical Kits are a bottleneck for Medical Station upgrades. The most consistent farm is to prioritize Dam Battlegrounds and hit Testing Annex first: it stacks medical containers close together so you can loot and reset quickly.

Where it spawns
Treat Rusted Shut Medical Kits like high-tier medical loot: focus locations with dense medical containers (cabinets, wall med boxes, lockers, and clinic rooms). On Dam Battlegrounds, Testing Annex is the best single stop because you can check many medical containers in one sweep.

Fastest loop (Testing Annex)
- •Queue Dam Battlegrounds with a light kit (you are here for speed, not PvP).
- •Path straight to Testing Annex and clear the medical rooms first.
- •Loot every wall cabinet, med box, and locker before touching low-value office clutter.
- •If you find a Rusted Shut Medical Kit, safe-pocket it immediately if possible.
- •Rotate to the nearest extract and leave early—repeatable short raids beat one long risky run.
Backup spawns
If Testing Annex is hot or already looted, pivot to any Dam medical-adjacent interiors with cabinets and lockers. The key is container density: you want fast checks and a quick exit, not a full-map roam.
Tips to farm it faster
- Run short raids: check your target building first, then leave.
- Skip heavy loot: time spent on low-yield props costs you more attempts per hour.
- Go solo-friendly: avoid prolonged fights—your goal is repeatable container rolls.
- Bundle goals: if you are also farming Surveyor Vaults, alternate routes so every run advances progress.
