ARC Raiders Spaceport Loot: Tech, Weapons, and Two Vaults

The Spaceport (named Acerra Spaceport on the official wiki) unlocks at 12 rounds and is the industrial, technological, and weapon-focused stop. Large buildings sit far apart across open concrete, so the loot logic is simple: the good stuff is inside the structures, not scattered on the apron.

Two vaults you will not find elsewhere

• Launch Tower Loot — the zipline doors at the base of the launch towers are locked. Find a Fuel Cell (they spawn outside, near ladder-tunnel entrances or fuel pods), carry it to the tower, and slot it into the generator to open the doors. At the top, two panels each unlock an adjacent lootable container.
• Hidden Bunker — someone hacked the Outskirts Bunker’s security. Find four buttons to unlock the doors and be the first to plunder what is inside. It runs as a Major event at 10 and 19 UTC.

Both are Spaceport-only and both attract every other Raider in the raid, so treat them as committed runs, not detours.

Keys worth carrying

Spaceport has five keys:

• Spaceport Trench Tower Key
• Spaceport Container Storage Key
• Spaceport Ground Control Key
• Spaceport Outskirts Bunker Key
• Spaceport Warehouse Key

The Outskirts Bunker Key overlaps with the Hidden Bunker event, so it is the highest-value key on the map. The rest open Weapon Cases and Ammo Cases in their named buildings.

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 01, 07, 13, and 22 UTC.
• Electromagnetic Storm (Major) at 04 and 16 UTC.
• Launch Tower Loot (Minor) at 06 UTC and Hidden Bunker (Major) at 10 and 19 UTC — the two vault windows.
• Matriarch (Minor) — the rotating boss event also cycles here (around the Launch Towers).

Off those, it runs Harvester, Prospecting Probes, or Uncovered Caches.

How to run it

Bring something that works past close range — the loadout page covers the kit. Clear one building, cross deliberately, and do not chase a container into the open. The container guide explains what each crate drops, and the map ladder shows where Spaceport sits in the unlock order. The tactics page covers the Hidden Bunker round length.
