ARC Raiders: Rusted Shut Medical Kit Location Guide

If you’re wondering where to find the ARC Raiders Rusted Shut Medical Kit to finally upgrade your Medical Lab from Level 2 to Level 3, you are not alone. These rare kits are a major bottleneck for mid-game progression, as you need exactly three of them (alongside 8 Antiseptics and 5 Surveyor Vaults) to unlock the Tier 3 Medical Station. Unlike basic scrap, Rusted Shut Medical Kits only spawn on medical beds, shelves, and cabinets inside dedicated medical zones across the ARC Raiders maps. While many players sprint straight to the massive Hospital in the Buried City map, that location is often chaotic, heavily contested, and looted dry within minutes. Fortunately, there are several safer, highly concentrated farming spots across Dam Battlegrounds, Spaceport, and other zones that have a fantastic drop rate for these kits. In this guide, we will break down the absolute best locations to check, the exact rooms to breach, and how to safely extract with your loot intact.

Why You Need The Rusted Shut Medical Kit

The primary reason you are hunting for these kits is to upgrade your Medical Station to Level 3 in Speranza. This upgrade unlocks potent new healing items and better crafting recipes for your loadout. If you end up with extra kits later in the game, they can also be recycled into Antiseptic, which is another crucial medical crafting component.

Best Farming Spots In Dam Battlegrounds

The Dam Battlegrounds map offers some of the most consistent—and slightly less contested—medical loot spawns in the game.

The Testing Annex (Top Recommendation)

The Testing Annex, located in the southeastern part of the Dam Battlegrounds, is arguably the most reliable farming spot in the game. Specifically, you want to head to the western side of the building on the second floor. Here, you will find a hallway packed with medical tables, drawers, and shelves that frequently spawn the kits. As a bonus, this building is located right next to the Red Lakes Balcony Lift, making for a very quick and easy extraction once you secure the item. Just watch out for roaming Leapers and Rocketeer ARCs outside.

Research And Administration Building

If the Testing Annex is empty, head over to the Research and Administration building. You need to make your way to the top floor (above the reception area). Zip line up, take a right, then a left, and go all the way to the end of the hall to find a dedicated medical room that frequently spawns these kits.

Best Farming Spots In Buried City

Buried City has the largest concentration of medical loot, but it comes with a high risk of PvP encounters.

The Hospital

Located in the northernmost part of the map, the Hospital is the only dedicated, purely medical point of interest in the game, meaning the loot pool isn’t diluted by commercial goods. It spans three floors, with the top two floors packed with medical beds and loot. However, because it is the most obvious spot, it is highly contested by other players and is often picked over quickly.

Plaza Rosa Pharmacy

A fantastic alternative in the Buried City is the Pharmacy located in Plaza Rosa. You will usually need to breach the front door to get inside; if the breach prompt is there, you know the building hasn’t been looted yet. Close the door behind you and check both the ground floor shelves and the upper rooms. This spot is highly efficient because there is a zipline extraction point right outside, allowing for fast, low-risk farming runs.

Alternative Spot: Spaceport Departure Building

If you are playing on the Spaceport map, there is a very reliable medical room hidden away. Head to the northeast corner of the Departure (or Arrival) building and go to the top floor. Look for the dedicated medical room; it contains multiple beds and cabinets and is a great quiet spot to check if the main maps are too hot.

Farming Strategy Summary

Pro Tip: As soon as you find a Rusted Shut Medical Kit, immediately move it into your Safe Pocket. Because they are quite rare, you do not want to lose them to a random sniper or ARC encounter on your way to extraction.
