ARC Raiders Expedition 4 Window Strategies to Smash the 100k Damage Milestone for Permanent Rewards
Category: ARC Raiders Posted: Jul 13, 2026 Views: 10
During this period without major updates, one of the few ways to make meaningful progress in ARC Raiders is by participating in Expeditions to earn permanent rewards that will benefit you in future seasons.
During the two-week Expedition 4 window starting July 7, completing a mission to deal a cumulative total of 100,000 damage will unlock random blueprints and Raider Tokens as rewards!
Meeting this requirement takes some skill, as 100,000 is no small figure. While you can still earn rewards by hitting lower milestones if you don't reach the ultimate goal, more is always better!
With that in mind, here are some tips on combining map features and enemy types to maximize your damage output in a short amount of time.

Farming in Close Scrutiny
Since the event window hasn't reset yet, you can use any weapons currently in your inventory. However, we recommend prioritizing Hullcracker and Jupiter, and fully upgrading Hullcracker if possible.
Jupiter is ideal for engaging enemies at a distance, allowing you to pull distant ARC units closer, while Hullcracker is a powerful weapon for taking down heavy ARC units.
In addition to firearms, we recommend bringing plenty of mines or grenades, such as Wolfpacks or Deadlines. If you lack them or don't have enough, you should immediately buy IGGM ARC Raiders blueprints and craft the gear in the workshop.
Once your gear is set, avoid simply entering the map for a raid in the default state; instead, wait for events to spawn for greater efficiency. We recommend starting with Close Scrutiny event.
Stay on the battlefield for as long as possible during the event, at least 30 minutes, while constantly moving toward ARC Assessor's location. Getting within effective range of this enemy allows you to eliminate numerous smaller ARC units.
New ARC Assessors will drop in every few minutes; as you move between them, you can continue racking up damage by eliminating smaller ARC units along the way.
With enough skill, you can deal up to 20,000 damage in a single Close Scrutiny run. Furthermore, the specific layout of the map doesn't matter much during Close Scrutiny event; simply keep moving toward the various ARC Assessors and eliminate any enemies you encounter along the way.
Early in Expedition 4 window, facing off against Rocketeers and Vaporizers solo during Close Scrutiny can be challenging, as other players will also be hunting them.
You risk not only losing the kill to a competitor but also being taken out by aggressive PvP players.
However, now that the event window is past its halfway mark, the situation has eased up, making it a great time to get involved. If your gear is powerful enough, you can also try taking down Bastions and Bombardiers.
Farming in Hidden Bunker
This event takes place exclusively on ARC Raiders Spaceport map. Its advantage lies in its simple mechanics, with the enemy roster consisting primarily of Bastions and Bombardiers mentioned earlier. With a bit of luck, you can rack up as much as 40,000 damage in a single run.
To participate, head deep into Spaceport Departure Building after the event spawns. ARC units are more likely to appear at specific spawn points there; once you kill one, the next will respawn in about 5 to 10 minutes.
While waiting for them to respawn, you can scour other areas of Departure Building and eliminate any other ARC units you come across.
Defeating Queen and Matriarch
As the most powerful heavy ARC units currently known, ARC Raiders Queen and Matriarch offer the best opportunity to accumulate massive damage in a single battle. They appear during Harvester and Matriarch events, respectively.
Keep in mind that maximizing your damage output against them requires a significant investment of resources, specifically items like Wolfpacks or Deadlines mentioned earlier.
As for the strategy to defeat these two ARC types, you are likely already familiar with it: focus your fire on their legs first, and once they lose their balance, attack their exposed cores.
Farming in Locked Gate
This event takes place on Blue Gate map and lasts for a full 40 minutes, giving you plenty of time to eliminate as many enemies as possible. The key is to keep a close watch on the areas surrounding the various checkpoints to spot more targets.
You can also move to higher ground above the checkpoints to gain a different firing angle and focus your attacks from there.
The most common high-yield ARCs remain Bastion and Bombardier; you may also occasionally encounter Leapers in outlying areas, which offer a chance to rack up some extra damage.
Exploring Buried City and Riven Tides maps
On Buried City map, you can locate more enemies by patrolling back and forth between several key areas.
After spawning on one side of the map, immediately travel to the nearest ARC spawn point; shoot any enemies you encounter, especially flying ones, while en route to your target zone.
Once you reach the area near the hospital, you will encounter clusters of Bastions. After eliminating them, head back to Old Town, clearing out any ARCs along the way.
As for Riven Tides map, its main advantage is an extremely high ARC spawn rate. In addition to the familiar heavy ground-based ARCs, flying enemies appear frequently.
Therefore, the key to dealing sufficient damage on this map is to secure a favorable vantage point and take down as many enemies as possible.
A solid strategy is to position yourself on the small hill overlooking the extraction point and utilize high-trajectory shots.
To accumulate the required damage quickly, consider dedicating a few days, such as the weekend, to focusing on these missions and earning rewards. These rewards will help you progress faster in Season 5!
