Quick Scoop: Unlocking Arc Raiders' Spaceport Hidden Bunker The hidden bunker on the Spaceport map in Arc Raiders is a high-loot hotspot introduced in a November 2025 update, sparking massive forum buzz on Reddit's r/ArcRaiders and YouTube guides. Gamers describe it as a tense PVP magnet packed with ARK enemies like bastions and wasps once activated. Trending since launch, it's part of dynamic map conditions that keep raids fresh into 2026.

Bunker Location

Nestled southwest of the departure building , just outside Spaceport's walls in the "Fuel Lines" and "Fuel" zones. Look for a prominent metal door set into the ground —it's unmarked on the map but hard to miss amid industrial ruins. Multiple entrances (3-4) lead inside, making team flanks viable but risky.

"The actual location of the bunker is about southwest of the departure building, just outside the walls of Spaceport. There's actually multiple entrances."

Activation Steps

Unlock by powering up 3-4 white antennas scattered around—each triggers enemy waves for high-stakes action. Here's the breakdown from player guides:

  1. Antenna #1 : Northeast of "Fuel Processing," on a warehouse rooftop northwest of launch towers—climb ladders.
  1. Antenna #2 : Central map, next to a large industrial structure.
  1. Antenna #3 : West "Fuel Lines," behind a rusty container.
  1. Antenna #4 : Southwest "Fuel" sector, in a building with collapsed roof.

Once all activated, the door unlocks automatically. Squad up—12+ raiders often swarm for the loot haul.

Inside the Bunker

Expect tons of premium loot like data drives, weapons, and gear, plus puzzles (e.g., data terminals). Heavy resistance includes bastions, bombardiers, wasps, and hornets—pure chaos. Forum tips: Coordinate satellite alignments first for event triggers.

Player Perspectives

  • Reddit Solo Tip : "Spot it by the metal door in Fuel zones—antennas spawn waves, so stealth first" (60+ upvotes).
  • YouTuber View : "AMAZING LOOT but glitched terminals can wipe progress—team or bust".
  • Casual Debate : Some call it "unsolved mystery" for deeper puzzles; others grind it daily for meta builds.

This Spaceport secret exploded in late 2025 forums, with guides still trending amid patch tweaks. Dive in during your next raid!

TL;DR : Southwest of departure building outside walls; activate 4 antennas in Fuel zones for access. Epic loot, brutal fights.**
