Quick answer
TL;DR — The best repeatable loot farm on The Blue Gate is a tight underground loop: drop into the underground complex, hit the breachable room under the Reinforced Reception for its weapon case, sweep the weapon crates on both sides of the underground traffic tunnel, then push the color-terminal cache and the battery-locked Red Room before you extract. Blue Gate holds a pair of fixed breach rooms plus dynamically-spawned Security Lockers, and players report the underground can drop rare weapons and blueprints (multiple Survivor blueprints have come out of that one room). You do not need a full squad — it farms fine as a solo, low-kit run.
The catch: to breach the dynamic Security Lockers you need the Security Breach skill, which is the capstone of the Survival tree and costs deep investment to unlock. The fixed breach rooms and crates, however, are free to loot. Below is the full route, the loot to expect, the recent spawn change players are noticing, and the fastest way to run the loop.
The Blue Gate is one of ARC Raiders' largest maps — a mountainous valley of abandoned towns, fruiting orchards, and, crucially, an underground complex full of deadly ARC machines. It unlocks after you complete 18 rounds, and once it opens it becomes one of the most consistent loot circuits in the game, because so much of its value is packed into a small underground footprint you can clear in a single quiet run. The topside is big, exposed, and dangerous; the underground is where the density is. This guide breaks down the exact breach-room loop, what each stop drops, how the Security Breach perk fits in, and how to run it safely solo. Every location and mechanic here is cross-checked against the community-run ARC Raiders Wiki and Embark Studios' own patch notes.

What is the Blue Gate breach room?
"Breach room" is the community name for the breachable loot rooms in the Blue Gate underground — sealed rooms you have to break into rather than open with a key. The most-farmed one sits directly under the Reinforced Reception, and it reliably holds a weapon case along with assorted crates. Community maps mark a pair of these fixed breach rooms, and they sit alongside the map's other underground riches: weapon crates on both sides of the underground traffic tunnel, keycard-gated rooms, and the puzzle-locked Red Room.
This is separate from — but often confused with — Security Lockers (what most players mean when they say "security breaches"). Security Lockers are dynamic containers that must be forced open with the Security Breach skill; the fixed breach rooms are open to anyone who can reach them. A strong Blue Gate run hits both: the guaranteed breach room first, then any Security Lockers that spawned that raid.
Why bother with Blue Gate specifically? Because the underground concentrates high-tier interiors into a route you can run in a few minutes, and because it is quieter than the topside — most third parties fight over the surface POIs. As one raider put it after an hour on the loop, the breach room alone had handed them three Survivor blueprints over their playtime. That is blueprint-tier value from a single room, on a solo naked run.
How do you reach the Blue Gate underground breach room?
The underground is accessed through several entrances scattered across the surface — ziplines, hatches, and stairwells that funnel down into the tunnel network. The fastest line to the primary breach room:
- Drop into the underground via the nearest entrance to the Reinforced Reception (a zipline route gets you down quickly and avoids the open surface).
- Breach the room under the Reinforced Reception — this is your anchor stop and your guaranteed weapon case.
- Sweep the underground traffic tunnel — there are weapon crate spawns on both sides of the tunnel, so do not clear only one wall and move on.
- Push toward the color-terminal cache, then the Red Room if you found batteries — the Red Room is a battery puzzle that needs three batteries to open, and it rewards a high-value chest.
If you are carrying batteries early, prioritize the Red Room; if not, keep the loop compact around the breach room and tunnel and extract once you cross your value threshold. Discipline beats greed here — the underground is a dead end if a squad pushes in behind you.
What loot does the Blue Gate breach room drop?
The underground loop mixes guaranteed containers (breach room, crates) with the RNG of Security Lockers. Here is what each stop is worth:
| Stop | Access | Notable loot | Priority |
|---|---|---|---|
| Reinforced Reception breach room | Breach (free) | Weapon case, crates | High — anchor stop |
| Underground traffic tunnel | Open crates | Weapon crates both sides | High — easy value |
| Color-terminal cache | Solve terminal puzzle | Puzzle cache | Medium |
| Battery Red Room | Three-battery puzzle | High-value chest | High if you have batteries |
| Security Lockers | Security Breach skill | Weapons, Gun Parts, rare epic weapons + Complex Gun Parts | High (RNG spawn) |
Security Lockers are the wildcard. Per the community-run ARC Raiders Wiki, they "contain weapons and components. Rarely, they have a chance to contain epic rarity weapons and Complex Gun Parts," and the exact loot table is unknown. Blue Gate is not the densest map for these — it has the second-lowest number of Security Breach containers in the game — but the ones that do spawn are worth the detour when you already have the perk.
Do you need the Security Breach skill to farm Blue Gate?
Not for the fixed breach rooms and crates — those are free. You only need the Security Breach perk to force open the dynamic Security Lockers. It is the capstone of the Survival skill tree: you must invest 36 skill points into Survival first, then buy Security Breach with your 37th point, which in practice means you are unlocking it deep into your progression. You manage it via Raider → Skill Tree in the Speranza hub.
Whether it is worth it depends on your account stage. Early and mid-game, the perk turns otherwise-locked containers into premium loot and is one of the more reliable sources of high-tier gear. Late-game raiders often skip re-investing in it once they are swimming in kit — a common sentiment on r/ArcRaiders is that endgame accounts stop prioritizing it. If you are still building your stash, it pays for itself fast on maps like Blue Gate, Spaceport, and Stella Montis.

Were security breaches nerfed recently?
Players have noticed a shift. Since patch 1.7.0, Security Lockers changed fundamentally — the patch note reads: "Security Lockers are now dynamically spawned across all maps instead of being statically placed." That is why they feel random now: some raids the map is loaded with them, other raids it feels empty. Many spawn locations sit inside key rooms, so you will walk past some unless you are checking locked interiors.
More recently, the community consensus is that spawn rate feels reduced while the loot inside got slightly richer — raiders report fewer lockers per raid but better hauls from the ones they find (multiple pink guns and pink materials out of a single interior). Embark has not published a headline "nerf," so treat this as observed behavior, not a confirmed number: the spawns are RNG, and a dry run does not mean the mechanic is dead. Run the guaranteed breach room and crates regardless, and treat any Security Lockers as a bonus.
Best tips for running the Blue Gate loot loop
- Run it solo, low-kit. The loop was proven on a solo naked run — you do not need to risk a full kit to farm it, and going in light means you lose nothing if a squad catches you.
- It works in regular and event conditions. The breach-room farm holds up in the default condition and in modifier raids like Matriarch. Night Raid is quieter still if you bring a silenced weapon and can handle the reduced visibility.
- Silenced weapons and stealth win here. The underground is tight; a suppressor keeps you off other players' radar while you clear rooms.
- Check key rooms for Security Lockers. Because so many locker spawns hide inside locked interiors, the players who "never find any" are usually the ones skipping the key rooms.
- Set a value threshold and extract. The underground has limited exits — decide what haul is "enough" and leave before you get greedy. A guaranteed weapon case plus tunnel crates already pays for the run.
Blue Gate map conditions to know
The Blue Gate rotates through a long list of conditions that change how you farm it, including Lush Blooms, Uncovered Caches, Harvester, Husk Graveyard, Matriarch, Electromagnetic Storm, Night Raid, Cold Snap, Locked Gate, Hurricane, and Close Scrutiny. Night Raid is the community favorite for quiet farming (fewer sightlines for third parties), while Locked Gate adds security-code puzzles that gate extra blueprint rewards in the same underground area. Check the condition on the map-select screen and route accordingly — the loop is the same, but the risk profile changes.

Frequently Asked Questions
Where is the breach room on Blue Gate in ARC Raiders? The main breach room is in the underground complex, directly under the Reinforced Reception. Drop into the underground via a nearby zipline or hatch and breach the sealed room there — it holds a weapon case plus crates. There are two fixed breach rooms on the map in total.
Do I need the Security Breach skill to farm the Blue Gate breach room? No. The fixed breach rooms and the underground weapon crates are free to loot. You only need the Security Breach perk to force open the dynamic Security Lockers, which is a separate mechanic. The perk is the Survival tree capstone — 36 points into Survival, then your 37th point buys it.
Can you farm the Blue Gate breach room solo? Yes. The loop is designed to be run solo and low-kit — a "solo naked run" clears the breach room, tunnel crates, and Red Room fine. Going in light means you risk nothing if a squad pushes the underground behind you.
Does the breach room work in every map condition? It works in the default (regular) condition and in modifier raids like Matriarch. Night Raid is a strong pick for quieter farming, and Locked Gate adds security-code puzzles that reward extra blueprints in the same underground area.
Were the Blue Gate security breaches nerfed? Since patch 1.7.0, Security Lockers spawn dynamically instead of at fixed spots, which makes them feel random. Recently players report the spawn rate feels lower while the loot inside got slightly better. Embark has not confirmed a specific nerf, so treat it as RNG — and note that the fixed breach rooms and crates are unaffected.
What blueprints drop from the Blue Gate breach room? Loot is RNG, but the underground is a known source of weapon blueprints — players have pulled multiple Survivor blueprints from the Reinforced Reception breach room over repeated runs. Security Lockers can also rarely drop epic-rarity weapons and Complex Gun Parts.
