Master ARC Raiders: The Fastest Way to Unlock All 74 Blueprints
Blueprints are ARC Raiders’ real hard mode—scarce, spawnless, and essential. Your best shot comes when chaos hits: Night Raids and Electromagnetic Storms can spike Blueprint finds across the map, if you’re ready to capitalize.
ARC Raiders makes you work for your Blueprints. They don’t have fixed spawns, they drop rarely, and half the time it feels like you’d have better luck punching an ARC in the face and calling it a day. The trick is timing your runs with the game’s conditional events and knowing exactly where to go once those kick in. Here’s the actual, usable plan, plus a full breakdown of every Blueprint and where it comes from.
How Blueprint drops really work
Blueprints are a scarce drop with no specific spawn locations. You’ll see noticeably better results during Electromagnetic Storms (these have been the most reliable) and during Night Raids (still very solid). When one of those is active, head to high-value zones on Dam Battlegrounds, Buried City, Blue Gate, or Spaceport and loot fast. On the maps, areas outlined in red, orange, or yellow signal both threat level and loot tier. Yellow-tier spots tend to be quieter on players, which is nice when you actually want to stay alive long enough to open a locker.
Dam Battlegrounds: go here first when a storm hits
Testing Annex: During an Electromagnetic Storm, this place is a sneaky-good run. It’s a yellow-tier zone, so you won’t have a crowd breathing down your neck. Tear through Medical Containers, Lockers, and any container you can find. It’s one of those spots where thorough looting actually pays off.
Dam Control Tower: When a Storm or a Night Raid is live, this becomes chaos central. Bring Traps, Mines, and Grenades and expect Raiders to crash your party. Loot every Locker and Weapon Crate fast and bail before someone does the same to you.
Buried City: nighttime is money time
Santa Maria Houses: During Night Raids, these homes light up with valuable loot. Look for breach rooms inside; they hide Lockers, Backpacks, and Brown Drawers that can spit out high-tier Blueprints. You’ll find them just above Plaza Rosa on the southern part of the map.
Grandioso Apartments: Directly west of the Santa Maria Houses, so you can chain both in one Night Raid. This building has one of the best odds for rare drops like Tempest or Wolfpack at night. If you’re running Buried City during a Night Raid, skipping this is leaving money on the table.
Blue Gate: heavy loot, heavier PvP
Reinforced Reception (Underground): Up north on the map, this underground section is stacked with Security Lockers and locked rooms. It’s also a PvP magnet, and you’ll rarely bump into ARCs down there, so expect most of the danger to come from other players.
Village: Just west of Reinforced Reception. The whole area is dense with top-tier loot and, predictably, rival Raiders. Sweep every building and you’ve got a strong shot at multiple Blueprints.
Spaceport: consistent, with one big asterisk
Departure Building: On the west side of the Spaceport, left of the Launch Towers. It’s a red-tier zone, so assume Raiders and ARCs will crash the party. In return, you get Security Lockers and plenty of containers that can roll Blueprints and Trinkets.
Central Underground Bunker: Tucked under the Launch Towers between the Departure Building. It’s one of the safer places on Spaceport to farm with consistently good loot.
About those Launch Towers: yes, they’re lucrative, but you can only enter during the Launch Tower Loot dynamic event, which fires roughly every six hours. Great when it’s up, not great if you want reliable farming.
The big list: every Blueprint and where it comes from
There are said to be 74 Blueprints total in ARC Raiders. The majority are pure RNG drops. Some can come from Trials, quests, or the vendors in Speranza. A handful are tied to crafting after boss kills. The Traveling Tinkerer-only recipes aren’t included below. Also, quick heads-up: the weapon vendor’s name shows up with slightly different spellings in various places (Tai/Tia/Tian Wen). It’s the same 'Wen' vendor.

Quick strategy recap: wait for an Electromagnetic Storm or a Night Raid, then beeline to Testing Annex and Dam Control Tower on Dam Battlegrounds; Santa Maria Houses and Grandioso Apartments on Buried City (at night, especially); Reinforced Reception underground and the nearby Village on Blue Gate; and on Spaceport, bounce between the Departure Building and the Central Underground Bunker. Launch Towers are great, just not consistent.
If you’ve actually knocked out all 74, congrats and also I have questions. If not, this route should get you there a lot faster than praying to RNG in empty fields.
