SoulframeStella Montis
Stella Montis is the indoor ARC Raiders map, a mountain research facility added in update 1.2.0 on Nov 13, 2025 behind a community unlock that is now open. Its best loot is at the Cultural Archives, Medical Research and the Seed Vault, and it has its own Night Raid.
Stella Montis is ARC Raiders' indoor map, "a secluded research facility in the mountains" added with North Line, update 1.2.0, on Nov 13, 2025. It was opened by a community unlock, so TheGamer lists it as already unlocked, high difficulty, with two layers: the Seed Vault and Sandbox on the first, the Cultural Archives and Medical Research on the second (Feb 27, 2026). Tight rooms and short sightlines replace the long fights of the outdoor maps, and players kept running into each other at spawn until Embark improved the distance checks in 1.7.0. In the clip Embark calls it small and intimate, a map with no sky where you will run into other players.

The map has a reason to visit beyond coins. Update 1.7.0 moved the Aphelion blueprint drop here from the Matriarch and raised some item and blueprint spawn rates. See Blueprints and Shotguns and Battle Rifles.
Keys
| Key | What it opens |
|---|---|
| Assembly Admin Key | Door in the northwest near the assembly line |
| Archives Key | Right side of the map, at the end of the tunnels |
| Security Checkpoint Key | First door on the right in Security Checkpoint |
| Medical Storage Key | Door on the northwest wall of Medical Research |
Sources: Dexerto's key list (Apr 29, 2026) for the first three, TheGamer's key guide (Feb 14, 2026) for Medical Storage, which Dexerto's room list omits but its Mar 25 items page includes.
Embark's fixes confirm a locked room in Medical Research, where players outside it could be set on fire until update 1.23.0. All keys are on Keys.
Raider Hatches and extraction
Shacknews lists three hatches, against four on the launch maps: Assembly (eastern corner of Assembly), Eastern Tunnel (north of Seed Vault) and Sandbox (south corner of Sandbox), dated Nov 2, 2025: check in game. The Seed Vault also has an extraction, whose glitch letting players stay in after it closed was fixed in 1.13.0, and which got local lighting for night raids in 1.17.0. See Extraction and Raider Hatches. In the clip Arekkz Gaming extracts by a hatch beside the Assembly Workshop (Nov 29, 2025).
Enemies and Night Raid
The Matriarch and Shredder arrived in the same update as the map. Older guides call the Shredder a Stella Montis machine, but update 1.22.0 added Shredders to all maps. A Bastion also spawns here: it could spawn out of bounds and fire through walls until 1.13.0. See Bastion, Bombardier and Shredder. In the clip Embark says it needed an apex indoor enemy that could work in hallways.
Night Raid here is built around the dark. Update 1.11.0 lowered the lighting to make flashlights and listening matter, 1.13.0 turned most lamps off, and 1.17.0 brightened the darkest areas a little. The tracker listed it on Oct 31, 2026. Since 1.33.0, Night Raid allows no Free Loadout. More on Map Conditions.
The latest fixes came in update 2.3.0, for spots where players got stuck. The North Line quests open with this map: In My Image, Cold Storage and Snap and Salvage, the last asking for a photo of a Sandbox rover (PC Gamer, May 1, 2026). The story behind the update is on North Line.

BlueprintsARC Raiders blueprints unlock crafting recipes and are mostly random loot, best in high-loot areas, locked rooms and major map conditions. Since update 2.3.0 (Oct 27, 2026) the Dolabra, Bobcat, Equalizer, Jupiter, Tempest and Vulcano blueprints can drop in any major map condition, at a slightly lower chance.

KeysARC Raiders keys open locked rooms on each map and are used up when they open a door, and the Raider Hatch Key opens an extraction hatch. Dexerto listed the named keys by map on Apr 29, 2026; no reliable source has a full Pendola Pass list as of Oct 31, 2026.
-
Extraction and Raider HatchesTo extract in ARC Raiders, reach a map's exit, use the console and get inside before the round ends; it sets off an alarm and leaves by itself after 2 minutes. A Raider Hatch is a silent, instant exit that uses up a Raider Hatch Key. Pendola Pass uses a Ballistic Gondola instead.
-
Bastion, Bombardier and ShredderTo kill a Bastion or Bombardier in ARC Raiders, hit the yellow leg joints to slow it, then the yellow canister or cylinder at the back. A Bombardier also relies on Spotters, so kill those first. A Shredder dies to its bottom thruster, with two Trigger Nades enough to finish one.
