The Locked Gate event on Blue Gate is the kind of thing you "just check out" and then suddenly your whole raid is about it. The tunnel network sits between Checkpoint and the Warehouse Complex, sealed behind heavy doors that won't move unless the lobby does the work. If you're chasing rare drops like an ARC Raiders BluePrint, this is one of the few moments where the risk can actually match the reward, but it's also where squads get greedy and sloppy.

Where the codes really come from

You've got one raid's worth of time, roughly forty minutes, to pull four different security codes from the map. They aren't on bosses or locked behind a mini-quest. They're mixed into regular loot containers, which means it's pure luck plus persistence. The four search zones are Raider's Refuge, Pilgrim's Peak, Reinforced Reception, and Ancient Fort. Sometimes you'll pop the first bin and get a code. Other times you'll clear room after room, hear gunfire outside, and still come up empty. The upside is duplicates can spawn, so even if another team's already been through, you might still find what you need if you keep looting instead of tilting and rotating out too early.

The spots that punish bad habits

Pilgrim's Peak is where confidence goes to die. Rocketeers can tag you from far out, and once they start lobbing explosives, you're not "taking cover," you're relocating. Ancient Fort is a different problem: mines. Lots of them. If you're the sprint-everywhere type, you'll learn fast, and not in a fun way. Raider's Refuge and Reinforced Reception don't have the same built-in hazards, but they're loud on the PvP radar. People don't even need to see you—just hearing shots there is enough to pull squads in like sharks.

Opening the gate without getting wiped

After you grab a code, you've still got to carry it to the Gate Control Room and slot it into the correct console. Nothing happens until all four unique codes are entered, and that last input is basically a flare in the sky. The doors start moving, and suddenly every team that was "busy elsewhere" is running straight at you. Try not to stack your whole squad on the entrance. Someone should watch angles, someone should listen for footsteps, and someone should be ready to bail with whatever you've already secured. And keep checking the extraction timer, because a perfect tunnel run means nothing if you're sprinting to evac with seconds left.

Making the loot matter after the fight

The tunnels are packed with the stuff everyone wants—high-tier materials, rarer crafting parts, and those blueprint-style finds that change what you can bring into future raids. But the real win is leaving with it. A lot of players blow the whole raid budget on the push, then realise they can't afford the rebuild. If you're trying to smooth that out, some folks use marketplaces like U4GM to pick up items or currency so they can stay geared and keep running events instead of farming from zero after every bad wipe.
