I wasted 18 minutes in Dam Battlegrounds opening random lockers before I realized Lance only cares about the right medical rooms. If you're chasing ARC Raiders Items while doing the Arc Raiders Medical Merchandise quest, the short version is this: search 2 containers in Dam's Research and Administration medical room, 3 in Buried City's Hospital, and 2 in Spaceport's Departure Building exam rooms. Wrong building, wrong floor, zero credit. Painful lesson.

Arc Raiders Medical Merchandise quest steps for Lance

Medical Merchandise is one of Lance's multi-map trader jobs, and since the Riven Tides update it sits inside that bigger progression grind of roughly 100 quests. It's not just busywork either. Lance's chain pushes you toward medical and bio research unlocks, trader rep, and later high-tier blueprint access like the Hullcracker blueprint and Magnetic Accelerators. If you run an account Expedition, though, quest progress and your skill tree reset. No shot, that one catches people off guard.

Where to search containers in Dam Battlegrounds

Start at the Research and Administration building in the lower-middle slice of Dam Battlegrounds. I usually hit it from the south side, climb the outer stairs near the red map edge, then slip into the upper floor from the back because the front gets messy fast. You can also use the elevator shaft zipline inside, land upstairs, turn right, and check the rooms with medical icons. Lance needs 2 containers from those medical rooms, not the whole building. If a teammate opens one while you're both in the objective area, it counts for the squad, which makes this part way less annoying.

Buried City Hospital is the easy part

The Hospital in Buried City sits around the upper-middle of the map and has that red loot marker, so yeah, everyone and their busted pistol seems to know about it. Here's the thing though: this is the cleanest step because any 3 containers inside the Hospital count. You don't have to sniff out one tiny room or stare at wall signs like a lost intern. I like pairing this run with Doctor's Orders since Syringes, Antiseptics, and other medical junk pop up often enough that the overlap feels like actual smart planning, not guide-writer cope.

How do you find the Spaceport exam rooms?

Spaceport is the step that made me alt-tab and grumble, not gonna lie. Go into the Departure Building through the main entrance, climb the broken two-part stairs to the first floor, then move down the hall and turn right into the next corridor. Look left in the darker roofed stretch for rooms with experiment benches and white chemical bottles. That's your exam room clue. Search 2 containers there and Medical Merchandise should tick off, assuming RNG hasn't spawned half the lobby on your backpack.

While you're doing all this, stack Lance errands when the map lines up. Prescriptions of the Past sends you back to Spaceport for records, Life of a Pharmacist points you at Arbusto Farmacia in Buried City, and On The Map asks for pings at Fuel Lines, the antenna near Fuel Control, and the Container Storage Building roof. Shani and Apollo chains can overlap too, from Picking Up the Pieces to The Trifecta's Wasp, Hornet, and Snitch parts, plus Apollo's blueprint photos and football magazine hunt. If your skill points look “missing,” check whether you ran an Expedition first; quests don't hand out most points, leveling from extractions and combat does. Rusted Gears? Scrap Yard and Buried City Outskirts are where I've seen them most, but exact drop rates still feel like guesswork. Bring a quiet loadout, let squad shared progress do the lifting, and if you're tuning your next ARC Raiders Weapon for these hot zones, favor survival over cute DPS math. Dead Raiders don't finish Lance quests.
