If you participated in the new Expedition missions in ARC Raiders, all your resources and levels will be reset, meaning you'll have to start from scratch.
Are you struggling to scavenge enough ARC Raiders items and resources? Or are you desperately searching for legendary blueprints you previously obtained, such as Jupiter or Equalizer?

Don't worry, I'll teach you how to quickly complete Harvester raids in ARC Raiders and introduce locations with high blueprint drop rates to help you acquire legendary blueprints.
Preparing for Raid
Adjusting opponent matchmaking
In the previous game mode, while painstakingly raiding and scavenging items, we also had to be constantly aware of other raiders who might suddenly appear and attack to steal our supplies, significantly increasing the difficulty of our raids.
Especially in single-player mode, completing a raid alone is already challenging; adding PvP interference makes a safe withdrawal even more difficult. Therefore, you can conduct about 10 raids without killing anyone before the actual raid, ensuring you remain completely friendly during the raid.
The system may analyze your gameplay and determine if you are a friendly player, thus adjusting your matchmaking. Afterwards, your opponents or teammates are more likely to be friendly players, reducing the difficulty of the game and allowing you to complete raids more easily.
Equipment setup
Before raids, be well-equipped, as you will encounter various situations in the game. Use your most commonly used weapons; there are no special requirements. If you want to kill some ARCs while looting blueprints, it's best to bring some powerful weapons.
In addition, you can prepare the following:
- 2 or more Safe Pockets: To store rare resources in case you lose them upon death;
- 5-10 Adrenaline Shots: To help you move quickly across the map;
- Some Shield Rechargers: To ensure sufficient defensive capabilities;
- Bandage or Herbal Bandage: To help restore health and mana.
In addition, if you wish, you can bring Raider Hatch Key, which will reduce the difficulty of your safe evacuation to some extent.
How to obtain Legendary Blueprints?
Complete Harvester Raid
Harvester is a map modifier. When this mod is activated, a Harvester building will spawn on the map, guarded by The Queen. You need to enter this building and complete the puzzle to obtain high-value items or a Legendary Blueprint as a reward.
Harvester is generally activated in these three maps:
- Dam Battlegrounds
- Spaceport
- The Blue Gate
If you don't want to clash with The Queen, you can slowly approach the building and observe ARC's movements. Once they leave Harvester entrance, attack decisively. You can use the zipline to quickly approach the entrance and then break in.
After successfully entering, it's best to remove your shield to prevent damage from the electric shock. Then, you and your teammates need to find three capsules, which will be hidden behind panels above Harvester. You can use a pickaxe to pry open these panels to obtain the capsules.
During the search, pay close attention to the color of the central pillar to assess potential dangers. If the pillar flashes red, immediately leave the ventilation door and wait at the archway to avoid fire attacks. If it flashes blue, an electric shock will occur inside the building, depleting your shield.
After finding all three capsules, insert them into the central pillar before the pillar flashes red. Otherwise, you'll need to reinsert them. Remember to destroy the panel on top of the pillar before inserting them.
Once all capsules are inserted, yellow buttons will appear on the interior walls of the building. Destroy them all, preferably by shooting them directly with a weapon. If you want to conserve ammo, you can use a pickaxe.
After successfully destroying them, three loot containers will appear on the central pillar. You can obtain legendary weapon blueprints from these containers, usually Jupiter or Equalizer.
After collecting the loot, ensure a safe evacuation. To avoid conflict with ARC, quickly evacuate to the nearest extraction point or Raider's Hatch while The Queen is distracted. Use the key you prepared beforehand to successfully evacuate with your loot.
Other obtain locations
Harvest raids are the most reliable way to obtain legendary blueprints, almost always yielding one. Alternatively, you can try looting containers on different maps, focusing on containers and locations with higher blueprint drop rates.
- Damp Battlegrounds: Ruby Residence, Pale Apartments;
- Buried City: Pharmacy Building, Marano Station;
- The Blue Gate: Breach Room, Village.
Theoretically, locations with a high density of loot containers, areas requiring extra effort to access, and containers with the highest blueprint drop rates will increase your chances of finding blueprints.
Especially considering the influence of map mods, such as Night Raid and Electromagnetic Storm, while increasing the difficulty of raids, also results in higher quality loot and a greater probability of finding legendary blueprints.
These are the easiest ways to obtain legendary blueprints in ARC Raiders. If you don't want to spend time searching everywhere, you can team up with your teammates to complete Harvest Raid. This is the most reliable way to obtain blueprints. If your strength allows, you can even challenge The Queen, whose wreckage may also drop rare loot.
In any case, after Expedition resets, you'll need to collect more powerful weapons to improve your strength. Good luck on your raids!
