ARC Raiders Update 1.39 Explained: Matchmaking update, New Dweller Set, Weekly Trials, and Loot Guide

Summary:

ARC Raiders New Update 1.39 may not introduce a flashy new map or game mode, but it quietly delivers one of the game's most meaningful gameplay improvements. The latest patch refines matchmaking by separating self-defense from aggressive PvP, improves combat audio, introduces the new Dweller cosmetic set, refreshes Weekly Trials, and makes collecting valuable ARC Raiders Items even more rewarding alongside several quality-of-life fixes. Here's why this update could have a bigger impact than many players expected.

1. Why the New Matchmaking Rules Could Change Every Raid

The headline feature of Live Update 1.39 isn't a weapon or a new enemy—it's another major iteration of ARC Raiders' evolving matchmaking system.

Self-defense finally stands on its own:

Previously, players who fought back after being attacked still contributed to their matchmaking profile, even if the system assigned less weight to defensive combat. While the intention was understandable, many players worried that simply surviving an ambush could make future matches more PvP-heavy.

The latest test changes that philosophy.

Now, only players who actively initiate combat affect their playstyle evaluation. If another squad attacks first and you retaliate, your response is treated purely as self-defense.

This distinction should create fairer matchmaking for players who prioritize exploration, looting, and completing objectives over hunting other Raiders.

Combat is judged by context, not just bullets fired:

The updated system also evaluates how significant each encounter is.

Long firefights involving heavy damage, knockdowns, and eliminations carry much greater weight than brief exchanges where both teams quickly disengage. Instead of treating every encounter equally, the system attempts to measure how committed each squad was to the fight.

That makes matchmaking feel less mechanical and more reflective of actual player behavior.

2. Here's How ARC Raiders Decides Who Started the Fight

One of the biggest questions surrounding the new matchmaking system was how the game determines aggression.

The first meaningful attack matters:

According to the developers, a squad becomes the defending side if opponents:

• Damage one of their teammates first

• Knock down a teammate first

• Eliminate a teammate first

The squad that initiates meaningful combat is considered the aggressor.

Third-party fights still count:

Players who join an existing firefight aren't treated as neutral observers. Entering an ongoing battle and dealing damage is still considered voluntary PvP participation, meaning it contributes to the matchmaking evaluation.

The clarification helps remove much of the uncertainty surrounding previous matchmaking tests.

3. Honest Player Feedback Won't Affect Matchmaking

Another welcome clarification addresses concerns about the in-game matchmaking surveys.

The developers confirmed that player feedback has no influence on matchmaking itself. Reporting an unpleasant PvP experience won't secretly adjust future lobbies or change hidden ratings.

For a community that has spent months discussing matchmaking fairness, this transparency is almost as valuable as the gameplay adjustments themselves.

4. The Hidden Quality-of-Life Improvements Players Shouldn't Ignore

Although matchmaking dominates the conversation, several smaller improvements deserve attention.

Weapon consistency has improved:

Damage inconsistencies affecting both the Secret and Wolf Pack weapons have been corrected, making firefights feel more reliable.

Better audio means better awareness:

Several sound improvements also arrive with Update 1.39.

Players should notice:

• Clearer footsteps while moving through water

• More distinct rolling sounds

• Improved environmental audio cues

In extraction shooters, better sound design often translates directly into better decision-making, especially during close-range encounters.

More bug fixes across the game:

Additional improvements include:

• Cosmetic fixes

• UI improvements

• Map adjustments

• Hideout visual fixes

• Proper stacking for several cosmetic accessories introduced in earlier updates

None of these changes are dramatic individually, but together they polish the overall experience.

5. The New Dweller Set Brings Classic Wasteland Style

Outside gameplay, the biggest addition is the brand-new Dweller cosmetic collection.

The outfit embraces ARC Raiders' post-apocalyptic identity with layered survival gear and extensive customization options.

Players receive:

• Three color variants

• Radio Mountaineer Backpack

• Burn Scar facial appearance

• Optional mechanical arm

• Interchangeable goggles, masks, gloves, hood, and accessories

Interestingly, removing certain equipment pieces changes the outfit's visual appearance, giving players additional ways to personalize their survivor without requiring multiple cosmetic sets.

Players who already own the Radio Mountaineer Backpack will also receive a reduced bundle price.

6. Weekly Trials Offer Several Easy Farming Opportunities

This week's Trials are relatively straightforward, making them good targets for efficient progression.

The easiest objectives:

Players can quickly complete objectives by:

• Opening containers inside Blue Gate

• Searching Raider Caches

• Using Light Ammo against Wasps

These objectives fit naturally into standard loot runs.

Blaze Grenade challenge requires planning:

One Trial asks players to deal damage using a single Blaze Grenade, not cumulative grenade damage.

Grouping enemies like Leapers or Bombardiers before throwing the grenade offers the best chance of maximizing progress.

Poppers challenge still needs testing:

One objective requires players to take damage from Poppers, but it's still unclear whether the game measures total damage received or simply counts successful hits.

The community will likely determine the optimal strategy over the coming days.

7. Blueprint Farming and One Unexpected Mystery

Players looking to expand their crafting collection should also check this week's exchanges and blueprint opportunities.

The Blaze Grenade blueprint requires several burner components, although dedicated farmers may prefer searching industrial containers around Loading Bay, Dam Primary Facility, and similar high-value locations instead of spending materials.

Meanwhile, one mysterious in-game message has sparked community speculation:

"Phantom targets have been spotted on Shani's radar."

The notification never appeared in the official patch notes, leading many players to believe it could be teasing an upcoming event, seasonal feature, or entirely new gameplay mechanic.

Considering ARC Raiders' history of subtle in-game hints, this message is unlikely to be accidental.

8. ARC Raiders Continues Improving the Details That Matter

Live Update 1.39 isn't designed to impress with flashy content drops. Instead, it focuses on refining the systems players interact with every match. Fairer matchmaking, clearer PvP detection, stronger audio feedback, worthwhile Weekly Trials, and intriguing hints about future content all make this one of the game's most meaningful quality-of-life patches. As Embark continues testing these systems, players should watch closely to see how matchmaking evolves—and whether the mysterious Phantom Targets become the next major chapter in ARC Raiders. Players looking to strengthen their loadouts may also choose to buy ARC Raiders Items to prepare for future content and tougher raids.
