The Role of Blueprints in Progression

Blueprints serve as the essential keys to crafting in Arc Raiders, enabling you to produce weapons, grenades, mines, and more at upgraded workshop stations. With the recent Northlight update, the total count has expanded from 68 to 74, incorporating designs for a new weapon, two grenades, and three mines. These additions promise craftable explosives and firepower, but acquiring them remains a challenge.

Early reports suggest the newest blueprints are scarce, possibly linked to unreleased events, unsolved puzzles, or temporary glitches on the freshly launched Stella Montis map. Despite this, blueprint hunting remains vital, especially post-patch 1.2.0, which balanced drop rates. Previously overabundant designs from Betatina now appear more moderately, while rarities like those from Tempest, Vulcano, and Bobcat have surfaced in confirmed drops. This shift creates a fairer playing field for collectors aiming to bolster their arsenal.

Timing Your Raids for Better Odds

One straightforward edge in blueprint acquisition? Opt for night raids. These sessions boost the likelihood of securing blueprints, though community chatter debates if it's through elevated item quality or sheer volume of loot. Either way, the result is more opportunities—perfect for steady advancement. The trade-off: heightened dangers from shadowy ambushes and bolder opponents. It's a classic risk-reward dance, rewarding the prepared with richer hauls.

For a quick overview of raid timing impacts, here's a simple breakdown:

Targeting High-Value Zones

Blueprints aren't evenly scattered; they favor specific hotspots. While any container has a slim chance, the probability spikes in designated high-value areas. These include locked rooms needing keys, intricate puzzle chambers (check our separate Bluegate puzzle walkthrough), and breach-required entries across maps. Parkour-accessible spots—think mid-zipline leaps or rooftop vaults—also elevate loot tiers, including blueprint potential.

Notably, these zones often overlap with weapon case spawns, amplifying their appeal. Puzzle rooms consistently deliver a weapon case, while key-locked areas scale with key rarity (higher tiers like purple yield better odds, though not guaranteed).

Essential Containers to Hunt

Focus your searches on reliable container types for blueprints. Weapon cases top the list: iconic and predictable in spawn points, with roughly 15% appearance rates map-wide, jumping to 50% in premium zones. Raider caches follow closely—these emit a distinctive ticking hum, easier to detect with audio's night mode enabled (it amplifies subtle sounds while muting blasts).

Other strong contenders include grenade cases (cylindrical grenade holders), medical duffel bags (med-kit staples), and those enigmatic black cases (rarer but potent). Red lockers get occasional nods for blueprint drops, though personal hunts haven't confirmed it yet. Even surveyors—those armored, fleeing orbs outdoors—drop blueprints reliably enough to justify the takedown, beyond their vault yields for upgrades.

Speculation swirls about blueprint types tying to specific containers or maps, but evidence points to broad randomness. Cross-map drops, like anvil designs from Spaceport med bags or Buried City cases, debunk strict limits. Without exhaustive data dives, treat such theories lightly.

To visualize container priorities:

Alternative Paths to Blueprints

Raids aren't the only avenue. At level 15, unlock Trials: weekly challenges demanding top scores in single raids (not cumulative). Rewards scale with performance, and every tier carries blueprint chances—prioritize easier ones for consistent gains.

A few designs sidestep pure luck: Lure Grenades, Trigger Grenades, Hullcracker Launcher (and its ammo) stem from quest completions. The Jupiter and Equalizer legendary energy weapons guarantee blueprints via Harvester event puzzles. The rest? Pure RNG, tilted by smart targeting of keys, puzzles, breaches, and cases.

Exploring Stella Montis for Fresh Farms

Unlocked through the community-driven Breaking New Ground event on November 13, 2025, Stella Montis stands as Arc Raiders' fifth map—a sprawling, two-layered research facility carved into northern mountains. Hype painted it as a blueprint paradise, but runs confirm standard drop rates amid its loot-packed corridors. What sets it apart: relentless indoor density turning every path into a potential farm route, offset by fierce PvP and debuting threats like the melee-rushing Shredder and hulking Matriarch. Approach with short-range loadouts (shotguns, SMGs, or craftable Venator AR) and Looting Mark II for dual-pouch security—extract at three blueprints to dodge losses.

Map Layout and Navigation

Stella Montis flips the script on open-air raids with tight tunnels, machine chambers, and sterile halls split across two levels. Entry via narrow, trap-laden tunnels funnels you into the core, with access points like airshafts, metro stations, and raider hatches linking zones. The upper layer hosts six key points of interest (POIs), while the lower expands with deeper facilities. Its darkness demands flashlight vigilance and corner-checks; no vast outdoors means ambushes lurk everywhere.

For quick orientation, here's a zone breakdown by layer and loot focus:

Prime High-Value Zones and Routes

The map's design chains high-value areas naturally—breach doors and key rooms abound, boosting container odds. Start at spawn-adjacent hotspots like the east lobby's security checkpoint (yellow zone): four breach-guarded floors mimic Buried City's pharmacy, packed with black raider containers ("blueprint boxes"), grenade/med spawns, ammo cases, and a lower-floor locked door. A duo exploit (one sprints corner, other jump-spams) clips through sans key, revealing weapon cases and extras—high-traffic, so ally up or fight.

For a full route: Tunnel in via Western/Eastern access (electrical/Old World loot en route), hit Sandbox for mechanical caches, zipline to Seed Vault (nature highs via airshaft), drop to lower Assembly (tech via raider hatch), loop Atrium-Medical Research-Cultural Archives. This 10-15 minute loop yields 2-4 blueprints on good nights, prioritizing breaches and parkour vents.

Secret Spots for Quick Grabs

Community scouts uncovered these underrated gems—ideal for smash-and-grab repeats with minimal kit:

• Supply Call Station: Match-variable; activate monitors, follow color-coded signs/sounds to terminals with raider caches.

• Assembly Workshops Turbines: High-quality tech materials; scan turbine bases for hidden weapon cases.

• Cafeteria Secret Room: Drawer loot leads to fuel cell-unlocked chamber with fruit crates (chick-leveling bonus) and potential med duffels.

• Seed Vault Riddle: Fuel cell (from west extraction room) unlocks crates; solve for guaranteed high-rarity pulls.

• North Sandbox Storage: Security locker + crates; power with three nearby batteries for blueprint-box access.

• Outside Storage: Sand-pile weapon crate spawns (~30% rate); low-traffic edge.

• East Storage Room: Drawer-heavy; rifle through for grenade cases and black boxes.

Combating New Threats During Farms

Stella Montis introduces the Shredder (close-range charger—kite with doorways, equip SMGs) and Matriarch (shoulder/chassis weak points—team heavies, cover in halls). These spike raid danger, but downing them yields surveyor-like blueprint drops. Solo? Evade Shredders via chokepoints; squads, flank Matriarchs for safer clears.

Quests and New Blueprints

Dedicated lines like "In My Image" (scan three androids) reward Looting MK. 2 and meds, funneling merits for cosmetics/utilities. Northlight adds craftables: Aphelion Rifle (energy burst), Trailblazer/Seeker Grenades, Pulse/Deadline/Gas Mines—hunt in facility ruins or event puzzles. Merits from exploration (up to 3600 for tiers) indirectly boost via trader swaps, but raids remain prime for RNG pulls.

Quick Smash-and-Grab Spots

For low-risk blueprint building, equip minimally (adrenaline shots suffice) and repeat isolated high-odds sites. Extract swiftly, safeguarding finds in your pouch—minimal entry value means little loss on death.

• Dreadnaught Battlegrounds: Bridge-end hidey-hole. Edge-drop, forward-vault to access (bypasses zipline need). ~50% weapon case, plus med/grenade potentials.

• Buried City (North Train Station): Remote breach room with dual breach boxes, weapon/grenade/ammo spawns.

• Buried City (Top-Floor Building): Underrated breach room amid traffic—loot and evade.

These build collections iteratively, minimizing exposure.

Extended Routes for Committed Raiders

Gear up with a Looting Mark II augment for dual pouches, then aim for three blueprints per run (pouch-safed pair plus one) before extracting. Diversify to evade crowds.

Spaceport Route (East to West, Reverse if Needed)

Start in vehicle maintenance (yellow): Couch-corner weapon case, upper breach room. Climb tower (wall/rope): Top weapon spawn, security locker. Fuel lines vertical pipe: Vault-in weapon case. Departure building SW (red): Breach staff bathroom—red lockers, shower-stall case. Unmarked tower: Top case, security locker. Arrival building west: Dual breach rooms (south prioritized for case), roof ladder case (med bag alt). Optional risky detour: Skylight drop to SE breach room case.

Buried City Route (West to East)

Morano Station breach (as quick spot). House attic window: Entry-adjacent case. Opposite window: Corner case. Next building kitchen counter: Rope-skip to case. Sheet metal bridge zipline mid-platform: High-value room, dual cases. SW bushes/vehicle: Raider caches. Grandioso rooftops: Low-odds cases (skip if crowded). Remote breach building top: Cabinets, cases, bags. Secret south rooftop jump-chain: Dual cases, caches in trees/alley. Plaza Rosa east pharmacy: Multi-floor breach density. Red Tower east window: Stair/railing cases. NE building stair railing: Case. Piazza Arbosto east pharmacy: Similar dense, slightly quieter.

Tailor to spawn—prioritize nearest, extract at value threshold.
