You see growing traffic around Dam Battlegrounds as players hunt for Expired Respirators, a key medical item tied to hideout progression. Community discoveries have reinforced the Testing Annex as the most reliable place to farm them, shaping common routes for efficient and lower-risk runs.
You need Expired Respirators to complete Stage 2 of the Trophy Display Project, known as Soaring Menaces, which calls for three specific units alongside other ARC components. Completing this step unlocks Photoelectric Cloaks that support stealth-focused play, while broader hideout upgrades continue to raise demand for advanced blueprints such as Vita Shot.
Where to Find Expired Respirators?
You get the best results by farming the Testing Annex on the Dam Battlegrounds. Medical containers cluster tightly here, and PvP pressure stays lower than major hotspots like the hospital.
Equip a Safe Pocket before entry so you secure finds immediately. After spawning, move south, take the main stairs up, then turn left to sweep cabinets, drawers, and shelves. Each run takes about 5–8 minutes, and consistent routes often produce all three respirators within a few cycles.
| Location | Why It Works |
|---|---|
| Testing Annex | Dense medical loot, fast extraction access |
| Stella Montis (medical area) | Calmer queues, slower but safer |
You can also pick up Cracked Bioscanners and Antiseptics along the way for other crafts. Play during off-peak hours if you prefer stealth, watch for sound cues, and keep Adrenaline Shots ready. Prioritize extraction points that allow loot-in-pocket exits.
