ARC Raiders Blue Gate Loot: The Flexible Farming Map

Blue Gate unlocks at 18 rounds and is the flexible farming map: an open valley, buildings, and underground tunnel routes let you stack several objectives in one run. That flexibility is exactly what makes it a good loot map — you are rarely forced into one lane.

The Locked Gate vault

Blue Gate has its own event: a clandestine group activates the gate’s emergency shutdown, and four key cards are needed to override it and uncover what they are hiding. It is the map’s headline vault, equivalent to Spaceport’s Hidden Bunker, and it only appears here.

Keys worth carrying

Blue Gate has four keys:

• Blue Gate Communication Tower Key — by the Communication Tower near the gate.
• Blue Gate Confiscation Room Key — the confiscated-goods area inside the Blue Gate Tunnels.
• Blue Gate Cellar Key — certain cellar doors near the gate.
• Blue Gate Village Key — an old village building.

The Confiscation Room is the standout: it sits in the Tunnels and holds confiscated goods, which is a denser payout than a random crate. The Village and Cellar keys are the quieter wins.

When loot value goes up

Community-reported windows (UTC times are community-sourced and pending official confirmation — see research/real-sources.md §A3):

• Night Raid (Major) at 04, 10, 17, and 19 UTC.
• Electromagnetic Storm (Major) at 16 and 22 UTC.
• Husk Graveyard (Minor) at 02 and 18 UTC, and Harvester (Minor) at 05 and 17 UTC for boss-adjacent parts.
• Matriarch (Minor) — the rotating boss event also cycles here (between Ridgeline and the Warehouse Complex).

Off those, it runs Prospecting Probes, Lush Blooms, or Uncovered Caches.

How to run it

Because the valley, buildings, and tunnels give you route choices, plan a loop that hits two or three key rooms plus a Night Raid window. The container guide lists what each crate pays, the keycard guide maps every door, and the map ladder places Blue Gate in the unlock order. The tactics page covers the tunnel routes.
