All Arc Raiders Trials and How to Complete Them (Week 18)

With the release of Expedition 2, Embark Studios has released a new set of Arc Raiders trials. These new trials, much like previous weeks, provide players with a variety of challenges, including fighting specific ARC enemies or simply looting as much as possible.

If you are looking to complete every Week 18 trial in Arc Raiders after the deployment of Arc Raiders Expedition 2, here’s everything you need to know.

All Arc Raiders Week 18 Trials (March 2)

There are a total of five Week 18 trials in ARC Raiders. While these are not limited by matches, you need to extract successfully for the Trial progress to count. If you fail to extract after completing a trial and die, any progress you’ve made in any one of the Trial quests will be reset to zero. Here is a full list of all Arc Raiders Trials for Week 18:

• Damage Leapers
• Loot Bird’s Nests (Buried City)
• Damage Spotters
• Open Arc Probes
• Search Containers in Medical Research Wing (Stella Montis)

These challenges will be live from March 2, 2026, till March 9, 2026. Here’s how you can complete each of these trials.

Damage Leapers

This trial quest sounds simple, but it can be a pain to get done since Leapers are agile ARC enemies known for their devastating pounce and shockwave pulse. You can find these ARC units throughout multiple locations in Arc Raiders. However, they are primarily found patrolling these areas:

• South of the Launch Towers POI (Spaceport)
• Near the Hydroponic Dome or Water Treatment (Dam Battlegrounds)
• Red Lakes Balcony/Lower Red Lakes Area (Dam Battlegrounds)
• Marano Park (Buried City)
• Barren Clearing (The Blue Gate)
• Ruined Homestead (The Blue Gate)

While you can take on a Leaper on any map in Arc Raiders, Dam Battlegrounds, and Blue Gate provide ample opportunities to deal with Leapers without putting yourself in harm’s way. When taking on Leapers, avoid fighting them in the open as much as you can, as they can leap towards you and close long distances easily. Staying inside allows you to avoid its powerful shockwave pulse and slowly chip away at the Leaper’s health. Instead of solely focusing on the central eye, try shooting at the Leaper’s legs to immobilize it.

Additionally, you can use Heavy Ammo weapons like the Anvil or Showstopper to damage Leapers more effectively, alongside Wolfpack Grenades, Trigger Nades, and Blaze Grenades. These grenades can stagger Leapers when you throw one at the beginning of their lunge, and empty your mag while it’s stunned.

You will gain around 1760 points towards your Trials score for every Leaper you take down, with the points going up to around 3,500 during a 2x map condition like Electromagnetic Storm. This means you need to take out around 3-4 Leapers to hit the 4,000 maximum score. If you are completing this trial during a 2x map condition, you can get it done with only 2 Leapers.

Loot Bird’s Nests

This trial quest is specifically tied to the Bird City map condition on the Buried City map in Arc Raiders. During this event, you need to keep an eye on the rooftops of houses in locations like Old Town, Plaza Rosa, and West Village. You can find Bird’s Nests inside the chimneys, and you can simply interact and search these chimneys to count towards your trials score.

It is recommended to bring a Snap Hook or Ziplines when trying to complete this quest, as many Bird’s Nests are on high rooftops that are not accessible by jumping and parkour. Additionally, you can find rare “Rubber Ducks” in these Bird’s Nests, which can net you a lot of profit in Speranza. While looting Bird’s Nests doesn’t seem as challenging, you will need to search 23 total Bird’s Nests to get 4,000 points and 3 stars in this trial. Additionally, you can search Bird’s Nests during the Night Raid map. This makes it so you only need to search 12 Bird’s Nests to reach the maximum score.

Damage Spotters

Unlike Leapers, who pounce on Raiders, Spotters are small, flying ARC enemies that essentially serve as the eyes exclusively for the Bombardier. As such, these units are found accompanying the Bombardiers during their patrol, which means if you see a Bombardier, the Spotters are somewhere close by. Here are some of the locations where you can frequently find Spotters in Arc Raiders:

• On the Roof of the Parking Garage (Buried City)
• East of Vehicle Maintenance (Spaceport)
• Raider’s Refuge (The Blue Gate)
• Primary Facility (Dam Battlegrounds, but only during Night Raids)

Remember not to kill the Bombardier before reaching 4,000 points, as this will lead to Spotters no longer respawning. Once a Bombardier notices you, it will send out two Spotters to keep track of you. These are not challenging to take down, as they are fragile and have no armor, and a few well-placed shots from any weapon can easily take them down. If you eliminate the initial two Spotters, the Bombardier will launch two more Spotters for you to take down.

Taking down a Spotter will grant you around 800 points towards your trial goal, which means you need to take out 5-6 Spotters to reach the high score. This means you only have to take out 3 Spotters during a 2x map condition like Electromagnetic Storm to reach 3 stars.

Open ARC Probes

Another simple trial quest in Arc Raiders is finding and opening Arc Probes. These are small, cylindrical pods that crash-land onto the map during a match before returning. Arc Probes do not have a fixed spawn and are found on all Arc Raiders maps. However, their frequency drastically increases during Electromagnetic Storms. It is suggested that you try to complete this trial on the Dam Battlegrounds map, as it features an abundance of Arc Probe spawns.

You can target the area between the Red Lakes and the Dam, as we usually find a ton of probes here. Additionally, you can head to the area north of the Electrical Substation, as that is another hotspot for Arc Probe spawns. While the Swamp area to the west of the Floodgates can also prove to be a good spot for this trial, the abundance of trees can make it harder for you to spot the Arc Probes.

Once you find an ARC Probe and decide to breach it, be ready, as the probe will emit a loud ping that alerts nearby Arc enemies of your presence. It is important to remember that you do not have to be the player who starts the breach to get credit. If you find an Arc Probe that another Raider has opened, you can simply search the remains and earn the trial points.

Searching one Arc Probe will grant you 667 points towards your Arc Raiders Trials score, which means you need to search 6 Arc Probes to reach the high score. Additionally, since these spawn frequently during Electromagnetic Storms, you only need to search 3 Arc Probes for 3 stars in this trial.

Search Containers in Medical Research Wing

For the last Week 18 trial, you will need to head to the Arc Raiders Stella Montis map, which is usually filled with PvP action. To make sure you don’t lose anything to other Raiders, it is suggested that you go in with a free loadout. Once you are on the Stella Montis map, you need to head to the Medical Research POI. Try to avoid any ARCs that you encounter and loot every single container you come across.

You need to search a total of 12 containers in the Medical Research wing to secure three stars in this trial, at which point you can extract. You can also perform this trial during the Electromagnetic Storm map condition to gain double the points, which means you will only have to search 6 containers to reach 3 stars.
