Completing the Ascending the Mountain Project in ARC Raiders requires gathering specific components across all four stages. Instead of wandering through looted areas, focus on high-yield container types: Stella Montis suitcases for Headphones, Seed Vault electrical units for Voltage Converters, and Port Authority trolleys for Rocket Thrusters. For rare items like Broken Guidance Systems, prioritize unlooted industrial containers in Port Authority and the Stacking Yard, and rotate routes immediately once a zone is depleted.

Ascending the Mountain Stage Requirements

Check your stash before deploying. Reserve materials for all four stages in advance; accidentally recycling a late-stage requirement creates unnecessary farming runs later.

Keep a shortfall list rather than hoarding duplicate junk. If your stash already has a Rocket Thruster, skip dedicated vehicle yards and focus entirely on your remaining bottlenecks.

Best Material Farming Locations and Route Strategies

Choose your deployment zone based on your missing items rather than routine. Group your objectives so container types and enemy spawns align with a clear extraction route.

Headphones: Stella Montis Luggage Runs

Prioritize suitcases and blue luggage across high-traffic transit points in Stella Montis:

1. Lobby & Atrium: Clear grounded luggage piles under benches and ticketing barriers.

2. Business Center: Search executive lounges, conference rooms, and perimeter luggage racks.

3. Spaceport Departures (Fallback): If you are running trinket circuits on Spaceport, sweep terminal luggage before committing to a separate Stella Montis raid.

Once you extract two Headphones, remove them from your active shopping list and stop farming luggage.

Voltage Converters, Wires, and Sensors: Seed Vault

Seed Vault offers dense clusters of electrical breaker panels and breachable cabinets:

• Store 8 Voltage Converters in your stash before recycling surplus electronics.
• Dismantle low-tier electrical salvage to complete the 20 Wires requirement.
• Search destroyed security androids and utility units for Sensors.
• Extend runs into Medical Research or Cultural Archives server racks only when extraction routes are secure.

Salvage Notice: Field salvage yields can differ from base workshop recycling rates. Check the salvage preview before breaking down Voltage Converters or Fried Motherboards.

Rocket Thruster: Port Authority & Rocket Assembly

Securing your single Rocket Thruster requires targeting heavy transit containers and flatbed carts:

• Port Authority (Riven Tides): Check small open-air cargo trolleys, transport carts, and loading dock platforms.
• Rocket Assembly (Spaceport): Inspect low rear shelving units, workbench racks, and heavy maintenance stands.

Rocket Thrusters are bulky; monitor your encumbrance so you can sprint directly to extraction upon finding one.

Broken Guidance Systems: Industrial Circuits

Target fresh, unlooted industrial toolboxes and sealed heavy crates:

• Run tight circuits around Port Authority's outer workshops and the Stacking Yard.
• If containers are already breached by competing Raiders, disengage and rotate toward extraction; lingering in cleared zones wastes raid time.
• Use the Hydroponic Dome on Dam Battlegrounds as an alternate industrial rotation if primary sectors are contested.
• Store your 3 Broken Guidance Systems directly in your secure container to avoid losing them on death.

ARC Combat Drops: Firing Cores, Gyros, and Regulators

Certain Ascending the Mountain requirements drop strictly from hostile ARC machines:

• Pop Triggers & Shredder Gyros: Engage standard patrol units on Stella Montis during luggage sweeps.
• Sentinel Firing Cores: Bring armor-penetrating weapons to Riven Tides and engage Sentinels from mid-range cover.
• Vaporizer Regulators: Organize dedicated hunts equipped specifically for heavy armor engagements.

Raid Survival and Resource Retention Rules

Gathering materials is only half the battle; bringing them home safely requires smart inventory and timeline management.

Check Rotating Traders Daily

Before loading into an extraction run, inspect trade listings with Celeste and rotating outpost merchants. Vendor inventories occasionally offer Wires, basic components, and rare items for trade bars, saving you high-risk deploy cycles.

Manage Weight Limits to Preserve Mobility

Heavy mechanical components and thrusters add substantial encumbrance. Exceeding your loadout weight threshold disables sprinting and jumping, leaving you vulnerable at extraction points. Drop replaceable common scrap to keep your mobility intact for rare mission turn-ins.

Verify Project Timers Before Expeditions

Do not assume unsubmitted components will persist across major seasonal resets or Expedition departures. Always check the active Project expiration timer in the mission menu, submit stage tiers as soon as they are complete, and finalize Stage 4 before undertaking long-term departures.

Where can I find Headphones in ARC Raiders?

Headphones spawn inside suitcases, luggage piles, and travel bags located throughout the Lobby, Business Center, and Atrium on Stella Montis. Spaceport Departures luggage is a viable secondary source.

What is the fastest way to get a Rocket Thruster?

Inspect open trolleys, maintenance carts, and low industrial shelving around Port Authority on Riven Tides. If that area has been looted, check the rear storage racks of Rocket Assembly on Spaceport.

Where do Broken Guidance Systems spawn?

Broken Guidance Systems are found inside industrial containers and heavy mechanical toolboxes around Port Authority and the Stacking Yard. If primary areas are depleted, rotate to Dam Battlegrounds industrial sectors.

How do I get Shredder Gyros and Sentinel Firing Cores?

These are direct combat drops from ARC machines rather than lootable containers. Shredder Gyros drop from destroyed Shredder units, while Sentinel Firing Cores require destroying heavy Sentinel units, commonly found across Riven Tides.

Can I buy Ascending the Mountain materials from vendors?

Yes, materials such as Wires, basic mechanical pieces, and occasional rare components rotate through vendors like Celeste. Check merchant inventories after each daily reset before deploying into raids.

Summary

Completing ARC Raiders' Ascending the Mountain Project comes down to running disciplined, container-specific farming routes while safeguarding rare components across all four stages. Prioritize hard-to-find bottlenecks—such as Headphones, Rocket Thrusters, and Broken Guidance Systems—keep them safe in secure slots, and avoid lingering in already-looted sectors. Keep weight limits below encumbrance penalties, submit completed stages promptly, and check vendor inventories regularly to reduce unnecessary surface raids.
