Ascending The Mountain project is the core content of ARC Raiders Update 1.45, and the event will run until October 5, 2026.
This project is closely linked to the game's storyline - mysterious ARC signals have been detected outside the existing pipeline network, pointing to a mountain range that Apollo believes is key to accessing Frozen Trail map, which will be released on October 8th.
This article will explain how to complete ARC Raiders Ascending The Mountain project.

About Raiders Ascending The Mountain Project
The project is divided into four phases, each requiring specific materials and offering different rewards.
Stage 1: Research High-Altitude Mechanics
Phase 1 focuses on researching basic mechanical and electronic components to begin theoretical research for high-altitude travel. The required ARC Raiders Items are as follows:
Mechanical Components (x10)
Crafted using 7 metal parts and 3 rubber parts at Refinery, or by searching for areas marked Mechanical on the map.
Pop Trigger (x6)
Defeat Pop Arcs (small, spider-like arc-shaped devices commonly found indoors) and loot their remains.
Explosive Compound (x10)
Higher drop rate on Dam Battlegrounds map's Hydroponic Domes.
Headphones (x2)
Search residential buildings, apartments, drawers, and cabinets - these loot items are especially easy to find on Burried City map.
Rewards for completing Stage 1 are as follows:
- Burletta IV Pistol
- Extended Light Mag III Attachment
- Silencer III Attachment
Stage 2: Begin Ignition Tests
Stage 2 introduces more advanced materials and electronics, propelling the project towards actual engine testing. Required materials are as follows:
Wires (x20)
Available through trade with Celeste (4 seeds per wire) or by looting distribution panels and generators on Dam Battlegrounds map.
Voltage Converters (x8)
Available through trade with Celeste for 10 seeds each, or by recycling ion sputterers found in voltage circuit breaker boxes and electrical cabinets within electrical zones.
Firing Cores (x2)
Destroy Sentinel Arcs, usually located near the research building on Dam Battlegrounds map.
Rocket Thruster (x1)
Search Assembly Workshops on Stella Montis map.
Rewards for completing Stage 2 are as follows:
- Wolfpack Grenades (x2)
- Deadline Mines (x2)
- Trailblazer Grenades (x3)
- Crash Mat Blueprint (x1)
Stage 3: Implement Landing Capabilities
The propulsion system is under development, and the project now focuses on developing safe landing mechanisms for mountain expeditions. Required materials are as follows:
- Ruined Parachute (x1): Can be searched in ARC Raiders Buried City map container.
- Crash Mats (x3): Crafted at the tool station using 1 Durable Cloth and 1 Electronic Component.
- Snow Globes (x5): Destroy Shredders in Stella Montis.
- Guidance Systems (x3): Search Grandioso Apartments and the surrounding residential buildings on Buried City map.
Rewards for completing Stage 3 are as follows:
- Powered Descender (x1)
- Raider Hatch Key (x2)
- Rascal Launcher IV (x1)
- Launcher Ammo (x30)
Stage 4: Final Adjustments
The final stage requires the most complex components, involving advanced electronic components and rare ARC enemy drops. Specific required materials are as follows:
Sensors (x4)
Available from Celeste, each costing 10 seeds; search server racks at Pilgrim's Peak on The Blue Gate and Launch Towers on Spaceport maps.
Regulators (x3)
Search for red lockers at Hydroponic Dome on Dam Battlegrounds map.
Advanced Electrical Components (x15)
Crafted at Refinery using 3 Wires and 2 Electrical Components. Also found in ARC Probes that randomly spawn on the map.
Vaporizer Regulators (x3)
Obtained by destroying Vaporizers commonly found in Riven Tides map or Close Scrutiny event.
Completing Stage 4 rewards the following:
- Hot Air Balloon Backpack Charm
- Tactical MK3 (Defensive) Augment
- Tempest Assault Rifle IV
- Kinetic Converter Attachment
Efficient Material Farming Strategies
Plan Multiple Stages at Once
The most important efficiency tip is not to focus on material collection for a single stage. However, backpack space is very limited, and the worst situation is leaving fully loaded with materials needed for the current stage only to find you've missed materials urgently needed for the next stage.
Therefore, you need to make a list of all the materials needed for the current stage and the next stage in advance. Upon entering ARC Raiders, focus not only on the materials needed for your current phase but also on all materials on your list.
For example, while searching for Headphones in Buried City residential area (Phase 1), you can simultaneously search for Guidance Systems and Ruined Parachutes needed for Phase 3. This allows you to progress in multiple areas with a single farm.
Prioritize Security Breach Containers
If you want to speed up material gathering and accumulate funds for rare components, Security Lockers are your best option. These special containers are scattered across every map, offering a significantly higher chance of dropping rare, high-value loot than regular containers.
However, to unlock these Security Lockers, you must invest in Security Breach skill in Survival skill tree. Many players overlook this, resulting in a large amount of loot going unclaimed.
Map-Specific Farming Strategies
Each map in ARC Raiders has specific types of materials suitable for farming. Choosing the right map is fundamental to efficient material farming.
For example, if you need common residential items, Buried City is your best choice; if you need mechanical and electronic components, then Dam Battlegrounds is your best choice.
That concludes this article about ARC Raiders Ascending The Mountain project. Finally, please remember that this is a timed project; you must complete it before October 5, 2026, which is before Frozen Trail update arrives. So, time is limited, so start your challenge now!
