With the final week of March upon us, ARC Raiders Week 21 Trials are officially open, running from March 23rd to March 29th, 2026.
Combined with the upcoming Arc Raiders Flashpoint on March 31st, 2026, now is the perfect time to complete weekly challenges, accumulate resources, and farm powerful ARC Raiders blueprints.
Below is a guide to this week's five trials, helping you quickly grasp the characteristics of each trial and the best methods for completing them.
Notably, completing trials during major map conditions will double your points. This mechanism significantly reduces the time needed to achieve three stars. Missions that previously required multiple runs can often be completed in a single run with the double points bonus.
Harvest Plants
In this non-violent trial, you only need to gather plants, without engaging in any combat. Avoiding direct confrontations with ARC enemies, this is the most relaxing trial of the week for players who want a relaxed experience and don't want intense battles.
Once you reach the ground, you need to look for and harvest plants like Mushrooms, Great Mullein, and Agave.
It's best to gather plants in Lush Blooms mode for the best rewards. Lush Blooms mode rotates approximately every two hours.
Note that any fruit you can gather, such as lemons, pears, or others, will not contribute to your trial progress. Because some plants don't count towards the trial, you'll need to focus on specific plants.
Destroy Ticks, Fireballs, and Pops
Ticks, Fireballs, and Pops are the most basic and easiest ARC enemies to defeat in ARC Raiders; they can be found in abundance on any map.
The Blue Gate and Stella Montis are the two locations with the highest numbers of Ticks, Fireballs, and Pops. The best way to eliminate them is to enter buildings or enclosed areas. These areas have narrow terrain, which restricts their movement and prevents them from scattering, making it easier for players to clear them in one go.
Any weapon type can deal with these ARC enemies; aiming for their weak points will be more efficient. However, when they gather in large numbers, things can get tricky, so it's best to ensure they don't cluster together.
Once you've eliminated enough Ticks, Fireballs, and Pops to reach three stars, you can successfully extract.
Damage ground-based ARC enemies
This trial requires you to deal damage to all ground-based ARC enemies. There are a wide variety of countable enemy types, providing you with multiple options, and it can be run concurrently with other trials, greatly saving trial time.
Currently, there are 13 types of ground-based ARC enemies that meet the requirements:
- Tick
- Pop
- Fireball
- Comet
- Turret
- Surveyor
- Sentinel
- Shredder
- Leaper
- Bastion
- Grenadier
- Matriarch
- Queen
Different enemies offer different points. For example, killing a Pop grants 400 points, while killing a Bastion grants over 2000 points.
This means that during the major map condition, you only need to kill one Bastion to achieve a three-star rating. This is the most efficient speedrun method this week, suitable for players who want to complete the trial quickly.
For a more stable and easier completion, it is recommended to enter Stella Montis in Night Raid mode and focus on clearing out Pops. Killing about five Pops will easily complete the trial and allow for a successful extraction.
Search containers in the Medical Research wing
This trial should be easy to complete. Just follow the steps below.
First, you need to go to Stella Montis. It's best to load the map during Night Raid to increase your chances of getting three stars.
After reaching the summit, head to the west side of the map and go to Medical Research Wing. Once inside, simply search around, looting all the containers you can find, and then successfully evacuate.
Disable mines during Locked Gate
This trial requires The Blue Gate to be loaded under Locked Gate map condition.
You need to find Explosive Mines on the surface; they are scattered throughout the map. Two good concentrations of Explosive Mines are on the slopes of Pilgrim's Peak and around Reinforced Reception, each providing 300 points. You need to disable 14 Explosive Mines to achieve three stars in this trial.
When you approach an Explosive Mine, you'll hear a beeping noise and see a red indicator light. Then you can slowly approach until you can disable it and repeat this process. It's recommended to carry plenty of Healings to prevent accidental explosions.
ARC Raiders Week 21 Trials are generally not very difficult. Utilizing map conditions effectively will earn you double points, significantly saving time. This week doesn't have any particularly challenging trials like "Get Hit by Lightning"; all trials are relatively simple and easy to complete. Whether you're a veteran player or a newcomer, you can easily complete all three-star challenges.
After achieving full stars, you'll not only receive a large amount of loot but also have a chance to earn blueprints, preparing for the upcoming Flashpoint update.
