Finding the Combat Mk. 3 (Flanking) blueprint in ARC Raiders can feel like chasing a ghost. Because it’s an Epic-tier augment blueprint, it does not have a single, 100% guaranteed fixed spawn point. However, the game’s loot distribution isn't entirely random either. By targeting high-value medical zones, specific container types, and matching them with high-tier map modifiers, you can dramatically swing the RNG in your favor.
📍 Best Farming Locations
The blueprint drops from augment-style containers, which include black security boxes, lockers, and blue medical drawers. Focus your runs on these three prime locations:
1. Buried City (The Hospital & Pharmacy)
This is widely considered the absolute best location specifically for the Flanking variant.
-
What to look for: Enter the main hospital building and search through the blue medical drawers and pull-out cabinets.
-
Key areas: Don't skip the locked card-key rooms if you have the resources, as players frequently report finding the blueprint tucked inside bins and wall cabinets here.
2. Blue Gate (Reinforced Reception Breach Room)
The underground area of Blue Gate is a premier general farming location for all Mk. 3 augments, though it is a notorious PvP hotspot.
-
What to look for: Head to the Security Wing in the underground area and look for the reinforced door that requires your Raider Tool to breach.
-
Key areas: Inside, search the long, rectangular black security containers, lockers, and the 5 to 6 grey metal wall-mounted racks. These wall racks have some of the highest community-reported drop rates for epic blueprints.
3. Stella Montis (Medical Research & Security Wing)
A slightly less contested alternative to Blue Gate, but still highly rewarding.
-
What to look for: Check the lobby security area and the locked medical rooms.
-
Key areas: Focus entirely on the medical bays and security lockers. Multiple players have confirmed pulling back-to-back Mk. 3 blueprints from these specific rooms.
🌪️ Recommended Map Conditions & Data Analysis
Your chances of finding epic blueprints scale heavily with Major Map Conditions. Raiding during standard day modes yields standard drop rates, but launching into specific weather and time events adds a massive multiplier to high-tier loot containers.
To maximize efficiency, keep an eye out for these three conditions:
The Numbers Game: Drop Probability & Efficiency
Data tracking from community farming runs shows why stacking map conditions matters. In standard daytime raids, pulling an Epic Mk. 3 blueprint from a standard container sits at an estimated 1% to 2% chance.
However, when you layer the right variables, the math changes significantly:
While an 8% top-end chance still requires multiple runs, you are essentially quadrupled your efficiency per container opened compared to running basic daytime matches.
If you find yourself struggling with the brutal drop rates or getting constantly eliminated by extract campers at Blue Gate, you can bypass the grind entirely. Trusted third-party marketplaces like U4N offer a secure alternative, where verified sellers have ARC Raiders blueprints for sale to help you complete your ideal loadout without the RNG headache.
💡 Speed-Farming Strategy: The "Naked" Cycle
To pull this off efficiently without losing your hard-earned gear to PvP "rats," the community utilizes a high-speed, low-risk strategy built around the 27-Minute Rule.
1.Go in Naked:Minimize Risk.
Drop into the map completely naked—no shields, no expensive guns, and no augments. At most, bring a single cheap weapon (like a Stitcher with 50 bullets) or a couple of Adrenaline Shots for stamina. You still retain your one Safe Pocket slot, which is all you need.
2.Check the Match Timer:The 27-Minute Rule.
The moment you spawn, check the clock. If you are farming the Blue Gate Breach Room, you must reach the door before the match timer hits 27 minutes left. If you get a bad spawn or arrive later than this, there is a 99% chance another Raider has already breached and cleared it.
3.Sprint and Loot:Target High-Priority Spots.
Ignore standard enemies and sprint directly to your target zone (the Hospital or the Breach Room). Open only the specific blue medical drawers, lockers, or black security boxes.
4.Secure or Reset:Instant Extraction Alternative.
If the Combat Mk. 3 (Flanking) blueprint drops, instantly drag it into your Safe Pocket. Once it is in there, it is permanently yours. You can then immediately hit ESC and surrender, or let another player eliminate you. If the room is already empty or the blueprint doesn't drop, surrender instantly to reset, re-queue, and start a fresh run.
Using this loop, a single farming cycle takes less than 3 to 4 minutes. Even with bad RNG, executing 15 to 20 fast naked runs an hour will inevitably land you the Flanking blueprint or one of its highly valuable sister variants.
