Stella Montis Arc Raiders – Complete Location Guide and Rewards Overview

Stella Montis — the hidden mountain facility of Arc Raiders

Stella Montis is one of the most atmospheric and mysterious regions in the game. Buried deep inside the northern mountain range, it remained sealed for a long time until the entire community joined forces to break it open. Now players can explore a preserved research complex filled with tight corridors, intact laboratories, cold steel halls, and dark tunnels leading into the heart of the mountain.

The region feels abandoned yet strangely functional: lights still flicker, doors respond to power, and equipment seems untouched. This eerie calm only enhances the tension as you move deeper into the facility.

How Stella Montis was unlocked

Phase 1 — Clearing the grounds

Players collected materials during their raids and contributed them to the global progression bar. Every donation pushed the community closer to opening the hidden facility.

Materials included:
– metal parts,
– fabric,
– plastic components,
– rubber pieces,
– chemical materials.

Even after reaching the personal reward limit, players could continue contributing for the sake of global progress.

Phase 2 — Establishing the route

Once the first stage was completed, players had to travel into the tunnel network and earn experience within the region. As soon as the collective XP goal was reached, Stella Montis opened permanently for all players.

Where Stella Montis is located

Stella Montis lies deep inside the northern mountain massif. It is a closed scientific facility built within solid rock. The environment stands out from the rest of the world:

• cold, almost sterile atmosphere,

• preserved laboratories and research wings,

• long corridors and multi-level passages,

• hidden chambers and controlled technical zones.

You can reach the location only through a system of tunnels — narrow, unstable, and occasionally dangerous.

Structure of Stella Montis

Upper Level

• unloading zone,

• entrance lobby,

• testing area,

• seed vault.

Lower Level

• assembly section,

• medical research wing,

• central atrium,

• cultural archive,

• service tunnels and technical passages.

This vertical structure makes the location layered and unpredictable, with safe paths suddenly turning into high-risk sectors.

Playing inside Stella Montis

Exploring this region feels very different from open outdoor combat. Here, survival depends on:

• controlling every corner,

• staying alert inside tight corridors,

• keeping a safe retreat path,

• reacting quickly to sudden noise or movement,

• adjusting to close-range engagements.

The narrow spaces reward precision and punish careless movement. Stella Montis constantly tests your awareness.
