Week 25 Trials in ARC Raiders (April 20-April 26) represent one of the more demanding late-season challenge sets, combining combat-heavy objectives with exploration and efficiency-based scoring. At this stage in the weekly rotation, the game expects players to already understand core mechanics such as extraction timing, enemy behavior patterns, and risk management. What makes this week stand out is not just difficulty, but how tightly packed the objectives are in terms of overlapping map activity.

 

Unlike earlier weeks where you could comfortably isolate one objective per run, Week 25 Trials are designed around multi-objective synergy, meaning the most efficient players complete two or even three objectives in a single raid cycle. The key to success is not raw firepower alone, but route discipline, target prioritization, and knowing when to disengage.

 

This guide breaks down each Trial in detail and explains how to consistently complete them without wasting multiple failed runs.

 

Understanding Week 25 Trial Philosophy

Before diving into individual objectives, it is important to understand how Week 25 is structured. Each Trial is scored independently, meaning progress is tracked per category based on your best run. However, the game strongly encourages efficiency because most objectives naturally occur in overlapping zones.

 

The core design philosophy this week revolves around:

High-density enemy zones that support multiple kill-based objectives

Interior loot routes that double as combat corridors

Boss encounters that reward participation, not just kills

Environmental modifiers that increase spawn rates or visibility

 

This means your success depends heavily on pathing decisions, not just combat performance.

 

Trial 1: Firefly Damage and Elimination

The Firefly objective is one of the most straightforward Trials this week, but it can still waste a lot of time if approached inefficiently.

 

Fireflies typically spawn in clustered patterns, especially in semi-enclosed industrial areas and transitional corridors between major zones. Their behavior is predictable: they tend to hover in groups, patrol in loops, and respond slowly to player presence unless directly engaged.

 

The most efficient approach is to avoid chasing individual targets. Instead, you want to enter zones where Fireflies naturally aggregate and clear them in bursts.

 

Weapon selection plays a major role here. Fast-firing weapons or area-of-effect tools dramatically reduce clear time, especially when Fireflies are grouped tightly. Precision weapons are less efficient unless you are targeting stragglers after an initial sweep.

 

A critical mistake many players make is overfarming this objective. Once you hit a strong scoring threshold, you should immediately rotate toward other Trials rather than attempting to "max out" Firefly damage in a single run. Since only your best run counts, additional time spent here rarely improves your weekly score.

 

Trial 2: Flying ARC Units Inside Spaceport Structures

This Trial is significantly more dangerous because it combines aerial enemy behavior with confined interior combat spaces.

 

Flying ARC units vary in threat level, but what matters most is their spawn location. Inside Spaceport structures, these enemies often appear near vertical corridors, open hangar ceilings, and broken infrastructure zones where line-of-sight is complex.

 

The challenge here is not just killing them-it is tracking them efficiently without wasting time repositioning excessively.

 

The optimal strategy is to move through interior structures in a controlled loop rather than rushing forward. This allows you to naturally encounter multiple aerial units while also staying within cover.

 

Sustained damage weapons are useful here, but burst damage becomes essential when dealing with higher-tier flying ARC units that may attempt evasive movement or temporary shielding. You can buy ARCR Items to get them.

 

One important optimization tip: do not separate this objective from Firefly clearing entirely. These two Trials frequently overlap in the same map regions, meaning a single well-planned run can contribute to both simultaneously.

 

Trial 3: ARC Probe Activation and Interaction

ARC Probes are one of the most efficient scoring mechanics in Week 25 Trials because they reward interaction rather than combat skill. However, their effectiveness depends heavily on map conditions.

 

Under normal conditions, probe spawns are moderate and scattered. Under enhanced environmental conditions-such as electromagnetic anomalies or storm variants-the frequency and visibility of probes increases significantly, making them much easier to chain.

 

The key to completing this Trial efficiently is movement discipline. You should never stay stationary waiting for probes to spawn. Instead, you should maintain a continuous rotation path through high-probability spawn zones.

 

When you locate a probe, interaction should be immediate. There is no benefit in delaying activation or attempting to "clear the area first." The scoring system rewards speed of interaction, not surrounding enemy clearance.

 

Experienced players often complete this Trial incidentally while moving between other objectives, which is the ideal outcome. If you are actively focusing on probes, it should still be done as part of a broader traversal route rather than a fixed farming spot.

 

Trial 4: Container Looting in Traffic Tunnel Zones

This Trial is less combat-intensive but requires strong route memory and efficient movement.

 

Traffic Tunnels are dense interior environments filled with interactable containers, including lockers, supply crates, and secured storage units. Unlike combat Trials, this objective rewards volume of interactions rather than difficulty or risk.

 

The biggest inefficiency players face here is unnecessary backtracking. Once you enter a tunnel route, your movement should be linear and continuous. Doubling back reduces both time efficiency and exposure to other objectives.

 

Enemy encounters inside tunnels should be treated as interruptions rather than objectives. You should engage only when necessary to maintain safe progression, not as a primary source of scoring.

 

The ideal execution is a full sweep from one entry point to another, opening every container along the way without hesitation. Because scoring is tied directly to interaction count, speed is the dominant factor here.

 

Trial 5: Queen and Matriarch Damage Contribution

This is the most demanding Trial of Week 25 and functions as a high-risk, high-reward objective.

 

Queens and Matriarchs are large-scale ARC entities with layered defensive mechanics and powerful area-of-effect attacks. However, the Trial does not require you to secure kills-only damage contribution.

 

This distinction is critical because it changes how you should approach the encounter entirely. Instead of focusing on survival or finishing blows, your goal is to maximize safe damage output during vulnerability windows.

 

These bosses typically cycle between defensive phases and exposed weak points. The highest damage opportunities occur during these windows, where coordinated or opportunistic burst damage yields the best scoring returns.

 

Positioning is extremely important. Staying too close increases risk of being eliminated and losing your progress for the run, while staying too far reduces damage contribution efficiency.

 

The most consistent strategy is to participate in group encounters whenever possible. Even uncoordinated public engagements can yield high scores if you focus on timing your damage during vulnerability phases.

 

Solo attempts are possible but significantly more time-consuming and risky, and they are generally not recommended unless you are highly geared and experienced with boss mechanics.

 

Efficient Week 25 Run Strategy

The most effective way to complete Week 25 Trials is not to treat each objective independently, but to combine them into a single structured raid flow.

 

A typical optimized run should follow this logic:

You begin in a high-density combat zone where Fireflies and flying ARC units overlap. This allows you to progress two Trials simultaneously while establishing early score momentum. From there, you transition into probe-rich traversal paths, maintaining constant movement while activating any probes you encounter.

 

Mid-run, you shift into Traffic Tunnel systems where container interaction becomes your focus. This phase is relatively low-risk and allows for consistent scoring without heavy combat pressure.

 

Finally, if conditions allow and a Queen or Matriarch encounter is active, you transition into boss engagement to finalize high-value damage contribution before extraction.

 

Final Thoughts

Week 25 Trials in ARC Raiders are designed to test efficiency more than endurance. Players who succeed consistently are not necessarily those with the best aim or highest gear, but those who understand how to chain objectives together into a single optimized raid loop.

 

If you approach this week with structured routing and disciplined decision-making, completing all Trials becomes significantly more manageable-and far less time-consuming than it initially appears. You will get more ARC Raiders Items rewards.
