All Week 21 Trials in ARC Raiders & 3-Star Point System
The Week 21 trials are currently active from March 23 to March 29, 2026. There are five challenges in the trials to complete with up to three-star ratings, earning 4,000 Points. Here are all the Week 21 trials in ARC Raiders.
- Damage ground-based ARC enemies
- Destroy Ticks, Fireballs, and Pops
- Disarm Mines during Locked Gate
- Harvest Plants
- Search containers in the Medical Research wing
Each trial has three thresholds for a star rating. Crossing a threshold guarantees you a corresponding rarity reward. You earn points by pursuing the challenges, and the points accumulate across all your runs.
NOTE: You do have to extract safely to lock in your trial progress and points. If you fail to extract after reaching a milestone for the trial, your points will not count.
In addition to earning points, your weekly rank will also be adjusted based on your performance. If you have a position among 1-30, you will receive a double promotion; if you are in 31-60, you will receive a single promotion, and any position above that will keep your current rank at the end of the week. Here are the points threshold and rewards for the trials in ARC Raiders.
| Stars | Points | Rewards |
| 1-Star | 1,000 | Uncommon items or Blueprints |
| 2-Star | 2,500 | Rare items or Blueprints |
| 3-Star | 4,000 | Epic items or Blueprints |
How to Complete All Week 21 Trials in ARC Raiders with 3-Star Ratings
The Week 21 trials include two challenges for eliminating ARC enemies, one for harvesting plants, one for disabling mines, and one for searching containers at Stella Montis. Your best bet is to run in the PVE lobbies so as not to get sidetracked while you are harvesting plants or fighting ARC enemies.
Damage ground-based ARC enemies
Completing the “Damage ground-based ARC trial” is easy, as it gives you the freedom to target either the smaller ARCs like Ticks, Pops, and Fireballs, or the ARC bosses, such as Bastion, Bombardier, Leaper, Queen, and Matriarch. For this challenge, I would recommend sticking with the smaller ARCs, as you can complete two trials this way. Focus on destroying the Ticks, Pops, and Fireballs to complete this and the “Destroy Ticks, Fireballs, and Pops” trial.
Destroying a smaller ARC enemy will give you about 300 XP on a regular map condition. It is best to load into a Night Raid for a 2x XP boost to get 600 XP per ARC. So, destroying any 7 small ARC enemies will get you to a three-star rating. As all of these ARCs spawn on every map, you can choose freely where you feel most comfortable.
Personally, I would recommend that you go to the Buried City. You can find numerous Ticks, Pops, and Fireballs inside the buildings and the train stations. You can go from one train station to the other, clearing out all ARCs, and then go back as they all respawn after some time.
Recommended Loadout for ground-based ARC enemies
- Light Shield
- 5x Bandages
- Anvil (II – IV) or Renegade (II – IV)
- 100 Medium Ammo or 60 Heavy Ammo
- Hullcracker (only for bosses)
- 3x Wolfpack (only for bosses)
Destroy Ticks, Fireballs, and Pops
Completing the “Destroy Ticks, Fireballs, and Pops” requires the same procedure as the previous trial. I recommend loading into a Night Raid on Buried City to find all three of these ARC enemies easily. Go to the Santa Maria Houses or visit all the active Train Stations to farm for all of these ARCs. Destroying each ARC will give you about 600 XP during the night raid.
Recommended Loadout for Ticks, Fireballs, and Pops
- Light Shield
- 5x Bandages
- Anvil (II – IV) or Renegade (II – IV)
- 100 Medium Ammo or 60 Heavy Ammo
Disarm Mines during Locked Gate
Completing the “Disarm mines during Locked Gate” trial will require you to load into the Blue Gate map while the Locked Gate map condition is active. After spawning in, you need to look for the mines on the map and disarm them by interacting with them. Crouching helps with spotting the mines on the ground.
Walk slowly and look ahead of you to spot any upcoming mines. Upon spotting a mine, disarm it by holding the interaction key. You will have to disarm 14 mines to complete the three-star milestone rating. The mines mainly spawn on these 4 key locations on Blue Gate during the Locked Gate event.
- Pilgrim’s Peak
- Ancient Fort
- Reinforced Reception
- Raider’s Refuge
Harvest Plants
Completing the “Harvest plants” trial will require you to harvest Great Mullein, Mushrooms, and Agave. The best method to complete this trial quickly is to load into a Night Raid for a 2x XP boost and visit the Galleria (Buried City) or the Spaceport Trench. The Galleria includes more than 15 spawn points of Great Mullein. There are multiple plants on each floor of the Galleria.
Go to every floor and harvest Great Mullein from the pots. The Spaceport Trench is another great option. The trench has Mushrooms and Great Mullein. Start from the east side of the trench to harvest mushrooms, and then keep going along in the trench to find Great Mullein. Harvesting each plant will give you 150 XP on a regular map condition, so it is best to do it in a Night Raid to get 300 XP per harvest. You will have to harvest any 14 plants to get a three-star rating.
Search Containers in the Medical Research Wing
For the final trial, you need to load into the Stella Montis map and head to the Medical Research Wing area. Looting a container under a regular map condition will give you 200 XP, so it is best to run a Night Raid for a 2x XP boost. Every container you open, you will get 400 XP, meaning you have to loot 10 containers to get a three-star rating.
While you are in the Medical Research wing, loot every type of container, such as lockers, breachables, medical bags, drawers, etc. All of these containers will count for this trial.
Tips for Completing Week 21 Trials with a 3-Star Rating
All Week 21 trials can be completed with a 3-star rating in a single day. Here are some of the best tips that will help you complete all challenges in a single day.
- If you are getting into PVP lobbies, die or surrender 4 to 5 times without shooting anybody to get into PVE lobbies.
- Run the “Locked Gate” map condition on the Blue Gate map once it is available. Head over to Pilgrim’s Peak, Ancient Fort, Reinforced Reception, and Raider’s Refuge locations to disarm the mines.
- Bring the Adrenaline Shots while looking for plants, ARCs, and mines.
- Use the Heavy Ammo weapons for more ARC armor penetration. These weapons will make the fight easy against strong ARCs.
- If you have Wolfpacks lying in your inventory, bring them to the raid to quickly defeat ARC bosses.
- Use the Survivor Augment and a Medium Shield with your Loadout. It will increase the survivability and the chance to make it out alive, even if you get downed.
