What to know
- Testing Annex (Dam Battlegrounds) is currently the most efficient farm spot.
- Stella Montis – Medical Research has strong spawns but heavy PvP pressure.
- Buried City hospital and pharmacies offer reliable medical container rolls.
- Look inside drawers, countertops, hospital beds, and medical-marked rooms.
ARC Raiders is a high-stakes extraction shooter where medical loot plays a major role in crafting, quest progression, and survival. If you are hunting the Rusted Shut Medical Kit, you need to balance spawn efficiency with survival odds. The item appears in medical-themed loot containers across multiple maps, but some areas dramatically outperform others in terms of speed and consistency.
Below is a quick glance at the most effective farming locations.
| Location | Map Area | Loot Density | PvP Risk | Best Containers | Efficiency Rating |
|---|---|---|---|---|---|
| Testing Annex | Dam Battlegrounds (bottom-right) | High | Medium | Drawers, countertops | Excellent |
| Stella Montis – Medical Research | West of Bastion, near loading bay | High | High | Beds, room containers | Very Good (Risky) |
| Buried City – Hospital | Northern sector | Medium-High | Medium | Medical rooms, cabinets | Reliable |
| Plaza Rosa Pharmacies | Buried City | Medium | Medium | Pharmacy shelves | Consistent |
| Piazza Arbosto | Urban sector | Medium | Low-Medium | Medical symbol buildings | Situational |
Why Testing Annex is the fastest route on Dam Battlegrounds
The Testing Annex in Dam Battlegrounds is widely regarded as the most time-efficient farming location. Positioned in the bottom-right corner of the map, this structure contains a dense cluster of searchable containers within a compact layout. When you enter, focus on office-style drawers and countertop surfaces, as these have the highest chance to roll medical loot pools.
The reason this location performs so well is simple: container density. You can clear the entire structure in a short sweep without crossing open sightlines for long periods. Compared to larger hospital complexes, the Testing Annex minimizes travel time between loot checks. If you spawn on the eastern half of the map, you can reach it quickly and extract before mid-match rotations intensify.
For faster clears, move room-to-room in a tight loop instead of zigzagging. Prioritize small container interactions over large chest-style containers since the Rusted Shut Medical Kit spawns most frequently in smaller medical storage units rather than industrial crates.
Stella Montis – Medical Research: high reward, high danger
Located on the western side of the Bastion near the loading bay, the Medical Research wing in Stella Montis is another high-probability spawn area. Beds inside examination rooms frequently produce medical-category loot, and you should check each room systematically.
However, this area is known for intense PvP activity. Many players route through here for both quest items and high-tier resources. If you choose this path, your approach matters. Enter through less exposed side doors when possible and avoid lingering in hallways. Clearing the upper floor first reduces ambush risk since most squads sweep from ground level upward.
While spawn density is strong, your extraction survival rate may drop if you overcommit. This location works best if you are confident in close-quarters combat or running in a coordinated squad.
Buried City hospital and Plaza Rosa pharmacies
Piazza Arbosto does not guarantee a high spawn rate, but any structure marked with a medical symbol has a chance to generate the Rusted Shut Medical Kit. This area tends to be less chaotic than Stella Montis, making it a safer secondary route if your primary farm fails.
Instead of treating it as a dedicated farm location, consider it a fallback sweep zone. If your spawn puts you nearby, it is worth checking before rotating elsewhere.
How to optimize your farming runs
If your goal is speed, spawn awareness is everything. When you load into Dam Battlegrounds near the southeast quadrant, rotate immediately toward the Testing Annex before mid-match convergence begins. Loot the structure fully, avoid prolonged fights, and extract early rather than chasing extra kills.
If you spawn closer to Stella Montis, assess gunfire density before committing. Enter only if the initial engagements settle quickly. In Buried City, chain together hospital checks with nearby pharmacies to maximize container interactions per minute.
The Rusted Shut Medical Kit belongs to the medical loot pool, meaning its spawn chance is tied to medical-designated containers rather than random world drops. Focusing on correct container types significantly increases your success rate compared to general looting.
Extraction success and survival balance
If you want the fastest consistent results, prioritize Testing Annex in Dam Battlegrounds. Use Stella Montis for higher-density rolls when you are confident in PvP. Buried City locations provide steady mid-risk alternatives, and Piazza Arbosto works as a flexible secondary sweep. By focusing on medical-specific containers and minimizing exposure time, you dramatically increase your odds of securing the Rusted Shut Medical Kit and extracting safely.
Even if spawn probability is high, extraction matters more. A fast, safe run from Testing Annex often yields better long-term efficiency than repeatedly contesting Stella Montis and dying. You should always factor risk versus repeatability into your farming strategy.
