After a short break for the Expedition Window, Weekly Trials are officially back in ARC Raiders, giving players a fresh opportunity to earn stars and push toward valuable seasonal rewards.

If you're looking to complete every Week 18 Trial efficiently, this complete guide breaks down each objective, the best maps to run, and the smartest strategies to secure three stars fast.

All Week 18 Trials in ARC Raiders

Here's the full list of Week 18 challenges:

·Damage Leapers

·Loot Bird's Nests (Bird City condition)

·Damage Spotters

·Open ARC Probes

·Search containers in the Medical Research Wing (Stella Montis)

Each challenge can be completed independently, so smart route planning and map selection will help you maximize efficiency.

How to Damage Leapers (Week 18 Trial)

Leapers are among the more aggressive ARC enemies in ARC Raiders, especially when encountered in open terrain. However, with positioning and the right weapon setup, they become manageable.

Best Map and Location

You can hunt Leapers on any map except Stella Montis. One of the best hunting grounds is:

·Launch Towers - Spaceport map

This area frequently spawns ARC activity and gives you strong structural cover to work with.

Strategy Tips

·Use heavy weapons for consistent mid-range damage.

·Stay in partial cover before engaging.

·Aim for the center core (middle ball) for optimal damage output.

·Avoid fighting in wide-open spaces unless you've cleared surrounding threats.

To earn three stars, you'll need to take down two Leapers during a major map condition. If you queue during high-intensity conditions, you can finish this quickly in a single run.

How to Loot Bird's Nests (Bird City Condition)

This Week 18 Trial requires a specific map modifier:

·Buried City during the Bird City condition

If Bird City isn't active, you'll need to rotate matches until it appears.

What to Look For

Once deployed:

·Head to building rooftops

·Search chimneys

·Interact to loot bird nests

These nests count toward the Trial progress and often contain valuable collectibles that can be sold back at Speranza.

Pro Tips

·Bring mobility gear to move between rooftops efficiently.

·Clear nearby enemies before climbing - rooftops can leave you exposed.

·Combine this objective with probe hunting if events overlap.

How to Damage Spotters (Week 18 Trial)

Spotters are flying support drones that assist Bombardiers by tagging players. While Spotters themselves don't deal damage, being marked can quickly escalate into a dangerous encounter.

Where to Find Spotters

You can complete this Trial on any map except Stella Montis.

They typically:

·Fly in pairs

·Hover overhead, scanning the area

·Respawn after being destroyed

Strategy for Fast Completion

·Bring a sniper or an accurate mid-range rifle

·Stay in partial cover while aiming upward

·Prioritize Spotters before Bombardiers engage

The good news? Each time a Spotter is destroyed, another spawns. That means you can farm them continuously without relocating.

Focus on clearing skies efficiently, and you'll secure three stars without much difficulty.

How to Open ARC Probes (Week 18 Trial)

This is arguably the easiest challenge of Week 18.

Where to Find Probes

ARC Probes spawn on any map, but the fastest method is to:

·Watch for the Prospecting Probes event

·Listen carefully for the distinct pinging sound

Audio awareness is critical here. If you hear metallic beeping nearby, you're close.

Safe Breaching Tips

·Clear enemies before interacting.

·Maintain situational awareness - probes often attract combat.

·Don't tunnel vision on the loot.

Simply breach and collect rewards. Repeat a few times, and you'll easily earn three stars.

If you're stacking objectives, consider combining probe hunting with Spotter damage runs.

How to Search Containers in the Medical Research Wing (Stella Montis)

Unlike most Week 18 Trials, this one specifically requires:

·Stella Montis map

Best Condition for Success

For optimal safety and extraction chances:

·Load in during a Night Raid

Night Raids reduce visibility and player traffic, giving you more breathing room.

Location Guide

·Head to the western side of Stella Montis

·Locate the Medical Research Wing

·Search and loot containers throughout the area

To earn three stars, you must:

1. Loot enough containers

2. Successfully extract

Extraction is the key factor here. Don't overstay your run once progress is complete.

Before entering Stella Montis, consider ensuring your gear and crafting setup are fully optimized. Access to stronger equipment - especially if you've chosen to buy ARC Raiders BluePrints for advanced weapon builds - can dramatically increase your survival odds during contested extractions.

Best Way to Complete All Week 18 Trials Efficiently

If you want to optimize your time:

1. Start with Spaceport or Buried City runs.

2. Focus on Leapers, Spotters, and Probes.

3. Finish with a dedicated Stella Montis Night Raid for the Medical Wing challenge.

Stacking compatible objectives in the same deployment will significantly reduce grind time while allowing you to farm valuable ARC Raiders Items for long-term progression.

Why Week 18 Is a Great Time to Push Trials

Compared to previous rotations, Week 18 challenges are less mechanically demanding and more focused on map awareness and light combat execution.

This makes it a strong week to:

·Earn early-season stars

·Build momentum toward rewards

·Farm probes and collectibles for additional value

If you took a break during the Expedition Window, now is an ideal re-entry point.

Final Thoughts

Week 18 Trials in ARC Raiders strike a solid balance between exploration and combat. With smart map choices, careful positioning, and efficient route planning, players can earn three stars across all objectives in just a few focused runs.
