After a short break during the Expedition Window, Weekly Trials are back in ARC Raiders, giving players another chance to earn stars and progress toward valuable seasonal rewards. These limited-time objectives reward efficient gameplay and map awareness, making them a great opportunity to collect useful materials and high-value ARC Raiders Items while advancing through the season.
If you want to complete every Week 18 Trial as efficiently as possible, this guide breaks down each challenge, the best maps to run, and the smartest strategies to secure three stars quickly.
All Week 18 Trials in ARC Raiders
The Week 18 Trials feature five objectives that can be completed across several maps. The full list includes:
·Damage Leapers
·Loot Bird’s Nests (Bird City condition)
·Damage Spotters
·Open ARC Probes
·Search containers in the Medical Research Wing (Stella Montis)
Since these tasks are independent, smart planning allows players to complete multiple objectives in a single deployment. With the right route, you can maximize efficiency while farming useful resources and collecting valuable ARC Raiders Items for future raids.
How to Damage Leapers (Week 18 Trial)
Leapers are among the most aggressive ARC enemies in the game. Their mobility and close-range attacks can make them dangerous if encountered without preparation. However, with the right positioning and weapons, defeating them becomes much easier.
Best Map and Location
Leapers can spawn on most maps except Stella Montis. One of the best farming locations is:
·Launch Towers – Spaceport map
This area regularly spawns ARC enemies and offers multiple structures that provide strong cover during combat.
Strategy Tips
To complete this challenge quickly:
·Use heavy weapons or high-damage rifles for consistent mid-range damage.
·Stay behind partial cover before engaging.
·Aim for the center core of the Leaper for maximum damage.
·Avoid open terrain unless you’ve cleared surrounding enemies.
To earn three stars, you must defeat two Leapers during a major map condition. If you queue during high-intensity conditions, you can often complete this trial in a single run.
How to Loot Bird’s Nests (Bird City Condition)
This Week 18 objective depends on a specific map condition.
Required Condition
You must deploy into:
·Buried City during the Bird City event
If Bird City isn’t active, simply rotate matches until the condition appears.
Where to Find Bird Nests
Once you deploy, look for nests in elevated locations such as:
·Rooftops
·Chimneys
·Tall building ledges
Interact with these nests to collect loot and progress toward the trial.
Tips for Fast Completion
·Bring mobility gear to move between rooftops quickly.
·Clear nearby enemies before climbing.
·Combine this objective with probe hunting if the event overlaps.
Bird nests often contain collectibles that can be sold for Space Dollars, making this trial a useful way to build your economy while gathering extra ARC Raiders Items.
How to Damage Spotters (Week 18 Trial)
Spotters are small flying drones that assist Bombardiers by marking player locations. While they don’t deal damage directly, being tagged by a Spotter can quickly escalate into a dangerous combat situation.
Where to Find Spotters
Spotters spawn on every map except Stella Montis. They usually:
·Fly in pairs
·Hover above players while scanning
·Respawn after being destroyed
Fast Completion Strategy
To complete this trial quickly:
·Bring a sniper rifle or an accurate mid-range weapon.
·Stay in cover while aiming upward.
·Destroy Spotters before engaging larger ARC enemies.
The good news is that Spotters continuously respawn, meaning you can farm them in the same area without relocating. Clearing them repeatedly will quickly earn you three stars.
How to Open ARC Probes (Week 18 Trial)
Opening ARC Probes is one of the easiest objectives in Week 18.
Where to Find ARC Probes
Probes can spawn on any map, but the fastest method is to watch for the Prospecting Probes event.
You can also locate probes by listening for a distinct metallic pinging sound, which signals their nearby presence.
Safe Breaching Tips
When interacting with probes:
·Clear nearby enemies first.
·Stay alert for other players approaching the event.
·Avoid tunnel vision while looting.
Breaching multiple probes in one run will quickly complete the challenge. This objective also pairs well with Spotter hunting or Leaper farming runs.
Searching Containers in the Medical Research Wing (Stella Montis)
Unlike the other challenges, this objective specifically requires the Stella Montis map.
Best Condition for Safety
For higher survival chances, deploy during a Night Raid. Lower visibility reduces player encounters and gives you more freedom to explore.
Where to Go
To complete the objective:
·Head to the western side of Stella Montis
·Locate the Medical Research Wing
·Search containers throughout the facility
To earn three stars, you must both loot enough containers and successfully extract.
Extraction is critical, so once the requirement is complete, avoid unnecessary combat and leave the raid safely.
Before attempting this run, it helps to ensure your gear setup is optimized. Some players choose to buy ARC Raiders Blueprints for advanced weapons and equipment, which can significantly improve survivability during contested extractions.
Best Route to Complete All Week 18 Trialsrategy:
1. Start with Spaceport or Buried City runs.
2. Focus on Leapers, Spotters, and ARC Probes simultaneously.
3. Finish with a dedicated Stella Montis Night Raid for the Medical Research Wing objective.
Stacking objectives in the same deployment saves time and allows you to farm extra ARC Raiders Items that can support your long-term progression.
Why Week 18 Is a Great Week for Trials
Compared to previous rotations, Week 18 Trials are relatively straightforward. Most objectives focus on enemy damage, environmental interaction, and exploration rather than complex mechanics.
This makes Week 18 a great opportunity to:
·Earn multiple stars quickly
·Build momentum toward seasonal rewards
·Farm probes and collectibles for extra profits
If you stepped away from ARC Raiders during the Expedition Window, this is an ideal time to jump back into the action.
Final Thoughts
Week 18 Trials in ARC Raiders offer a balanced mix of combat, exploration, and event-based objectives. With efficient route planning and smart map selection, most players can complete every challenge in just a few focused runs.
By stacking objectives and farming strategically, you’ll not only secure three-star completions but also collect valuable ARC Raiders Items that strengthen your inventory for future raids.
Whether you’re grinding the trials traditionally or choosing to buy ARC Raiders BluePrints to accelerate your equipment progression, careful planning will help you dominate Week 18 and push closer to the season’s best rewards.
