The final stage of Ascending the Mountain gives ARC Raiders players one last demanding collection challenge before they can claim the project's concluding rewards. Known as Final Tweaks, Stage 4 combines targeted map searches, Celeste exchanges, crafting, and combat encounters. Players keeping an eye on ARC Raiders Coins as part of their overall progression should still make project materials the main priority when preparing for this final set of objectives.

A Challenging Final Checklist

Stage 4 asks players to collect 30 Sensors, three Broken Guidance Systems, 15 Advanced Electrical Components, and three Vaporizer Regulators. The requirements are spread across several maps and systems, making a planned approach much more effective than simply searching everything encountered during a raid.

Inventory organization should happen before the first farming run. Project materials can quickly take up valuable space, especially when gathering 30 Sensors or crafting 15 Advanced Electrical Components. Leave enough room for the resources you specifically need and avoid filling your backpack with low-priority loot.

Farming Sensors

Sensors are the largest requirement in Final Tweaks. Players need 30, and Celeste offers one method of obtaining them by exchanging 10 seeds for each Sensor.

Players can also search server racks at Pilgrim's Peak on The Blue Gate and at Launch Towers on Spaceport. These locations provide a direct farming route for anyone who would rather search for the materials than spend seeds.

Using both methods can make the requirement much easier. Players with a large seed supply can obtain a portion through Celeste, then use targeted searches to complete the remaining amount. This flexible approach can save time and prevent the Sensor requirement from becoming a repetitive grind.

Searching Dam Battlegrounds

Broken Guidance Systems have a much more specific source. Three are needed, and players should search red lockers inside the Hydroponic Dome Complex on Dam Battlegrounds.

Because the requirement is only three items, a focused trip is usually sufficient if the appropriate lockers provide the necessary loot. Players should avoid remaining in the area longer than necessary after completing the objective, especially if they are already carrying other valuable project materials.

This location may also be familiar from earlier Ascending the Mountain objectives, making it easier for experienced players to incorporate the search into an established route.

Producing Advanced Electrical Components

The Advanced Electrical Component requirement is larger, with 15 needed. At the Refiner, each component costs three Wires and two Electrical Components. Crafting the entire requirement from basic materials therefore calls for 45 Wires and 30 Electrical Components.

There is also another way to obtain these components. ARC Probes randomly spawn on maps and can be searched for additional resources. Players should check these opportunities during normal exploration rather than making every raid exclusively about crafting supplies.

A combination of crafting and ARC Probe searches may provide the smoothest progression, particularly when the player's existing stash already contains some of the required materials.

Defeating Vaporizers

The final material is the Vaporizer Regulator, with three required. Vaporizers commonly spawn on Riven Tides, making that map the primary destination for players pursuing this objective.

Vaporizers can also appear during the Close Scrutiny event, providing another opportunity to collect regulators. Players who encounter the event while already progressing through the project can take advantage of it rather than organizing a completely separate farming session.

As always, combat should be balanced against the value of the resources already collected. Once three regulators are secured, extraction becomes the safest way to preserve progress.

Rewards for the Final Stage

Completing Final Tweaks grants the Hot Air Balloon Backpack Charm, Tactical MK3 Defensive Augment, Tempest Assault Rifle IV, and Kinetic Converter Attachment. These rewards make the final resource hunt feel meaningful and give players useful equipment after completing the project.

For players building their wider collection, buy ARC Items can be another consideration, but completing the project remains valuable because its rewards are directly tied to the Stage 4 milestone.

A Better Way to Finish

Final Tweaks becomes considerably easier when each material is approached according to its specific source. Use Celeste and targeted locations for Sensors, search red lockers for Broken Guidance Systems, craft Advanced Electrical Components when supplies allow, and hunt Vaporizers for the remaining regulators.

The final stage is ultimately a test of preparation. Instead of rushing through every encounter, plan routes around the materials you need, protect valuable resources, and extract as soon as the objective is complete. This approach keeps the final stretch of Ascending the Mountain organized and rewarding.
