How to Complete Weekly Trials in ARC Raiders (May 25-May 31 Guide)
The final week of May brings one more rotation of Weekly Trials in ARC Raiders, giving players a fresh set of objectives to complete before the calendar flips into June. This week’s challenges focus heavily on combat efficiency, environmental awareness, and knowing exactly where to find the right enemy types across different maps.
If you want to maximise your score and extract efficiently, here is a full breakdown of every Trial for the week of May 25 and the best strategies to complete each one.
All ARC Raiders Weekly Trials (May 25 - May 31)
This week’s Trials lineup includes a mix of looting objectives, combat challenges, and damage-focused tasks:
Loot Weapon Crates
Damage ARC enemies in the Red Lakes
Deal as much damage as possible using a Blaze Grenade
Deal Damage to Shredders
Damage Bombardiers
Each challenge rewards consistent play, but some require more precise planning than others—especially the Blaze Grenade and Shredder encounters. Plenty of ARCR Coins can easily help you complete your tasks.
How to Loot Weapon Crates Efficiently
One of the simpler Trials this week is looting Weapon Crates. While it can technically be completed on any map, most players will find better efficiency on Riven Tides, thanks to its layout and loot density.
The key detail here is that only Weapon Crates count. Other Raider Cache types will not progress the challenge, so it’s important not to waste time opening the wrong containers.
A good approach is to route through high-traffic loot zones, clear crates quickly, and then focus on extracting safely. Remember: progress only counts once you successfully extract, so surviving the run is just as important as looting.
How to Damage ARC Enemies in the Red Lakes
This Trial is much more straightforward and can be completed naturally during normal gameplay.
To complete it, players simply need to:
Travel to the Red Lakes area
Engage and damage ARC enemies
Extract successfully
The Red Lakes often feature active events, which can significantly speed up progress. These events may also offer bonus scoring opportunities, so it is worth prioritising them when they appear.
The best strategy is to stick with enemies you are comfortable fighting and use a loadout suited to consistent damage output rather than high-risk burst plays.
How to Maximise Damage with a Blaze Grenade
This is one of the more technical Trials of the week, largely due to how the objective is worded and how it actually functions in-game.
Despite earlier confusion suggesting multiple grenades might be involved, the challenge requires players to deal maximum damage using a single Blaze Grenade.
That means placement is everything.
The most effective strategy is to:
Find tightly packed ARC enemy groups
Use indoor corridors or chokepoints
Throw the grenade where fire can spread efficiently
The goal is to create chain damage rather than single-target hits. The more enemies caught in the burn zone, the faster this Trial completes.
How to Deal Damage to Shredders
Shredders are one of the more dangerous enemy types in this week’s Trials and are typically found in specific locations rather than across all maps.
To complete this objective, players should head to:
Stella Montis (primary location)
Buried City (only if the Security Lockdown condition is active)
Shredders are fast, airborne drones that deal heavy damage if left unchecked. Because of this, fights can quickly turn dangerous.
The best tactic is to focus fire on their thrusters at the start of the encounter. This disables their mobility and makes them much easier to eliminate before they can overwhelm you.
Once grounded or destabilised, continue applying consistent damage until the Trial requirement is met.
How to Damage Bombardiers Safely
Bombardiers are one of the most punishing ARC enemies in this week’s rotation, so this Trial requires careful positioning and patience.
They can be completed on most maps, with the exception of Stella Montis.
To handle them effectively:
Take cover before engaging
Open fire from a safe distance
Watch for spotter deployment
Immediately eliminate spotters when they appear
Reapply damage to the Bombardier
This cycle is important. If you ignore the spotters, your position will be exposed, making the fight significantly harder than necessary.
By alternating between Bombardier damage and spotter control, players can safely complete the objective without being overwhelmed.
Final Thoughts
This week’s ARC Raiders Trials are a balanced mix of simple objectives and more tactical challenges. While tasks like Red Lakes damage and Weapon Crates can be completed naturally, others—especially Blaze Grenades and Bombardiers—require more deliberate planning.
Efficient routing, map awareness, and smart engagement decisions will make a huge difference in how quickly you finish all five Trials.
With June approaching, this is the final opportunity in May to secure rewards before the next rotation arrives, so optimizing your runs now is key. A large supply of ARC Raiders Coins can be of great help to you at any time.
