ARC RAIDERS TWO-LEVEL GUIDE · UPDATED SEPTEMBER 2026

Stella Montis: two-level loot paths & corridor exits

Stella is an indoor close-quarters map where knowing which level you are on matters more than compass direction. Exfil Window models hallways and level connections instead of drawing through walls.

Hot zoneMedical Research

Safer valueAssembly Workshops

Route styleSpawn-based loop

Loot spots worth learning

High PvP

Medical Research

Medical containers, Vita Sprays and valuable technical materials. Multiple attack angles make lingering dangerous.

Strong value

Assembly Workshops

Weapon parts and components; yellow carts can be excellent searches. Watch for Pops and Fireballs.

Medium risk

Cultural Archives

Old World valuables and warehouse-style containers, with routes toward Lobby and eastern exits.

Medium risk

Seed Vault

A valuable lower-level starting point that pairs naturally with Sandbox or an eastern airshaft route.

Medium risk

Sandbox

A useful link between lower-level loot and escape options; treat every corner as an audio check.

Traversal

Lower tunnels

Less about peak loot and more about breaking contact, changing levels and reaching alternate exits.

Spawn-based runs

West / Assembly spawn

Medical-to-Workshop loop

Pause at spawn and listen for the neighboring team.
Search Medical Research quickly, or skip it if fighting starts.
Rotate through Cultural Archives.
Finish in Assembly Workshops.
Use the Workshop hatch or nearest modeled exit.

Lower / Loading spawn

Sandbox-to-Seed Vault loop

Move through Sandbox without sprinting blind corners.
Search Seed Vault by sections.
Use the eastern tunnel or airshaft as your default exit.
Drop to the lower level to break contact rather than backtracking.

Navigation habits

Before moving, identify both your named room and current level.
Close-range audio is your map: doors, metal floors and Shredders reveal traffic.
Do not begin looting at spawn until you know where the nearest spawn pressure is coming from.
Upper level favors value; lower corridors are often the better escape tool.

Calculate a Stella escape

Indoor routing follows modeled hallways and connections, but doors, firefights and map updates can change the actual crawl.
