ARC Raiders Harvester Puzzle Guide: How to Get Jupiter and Equalizer Weapon Blueprints Fast?

Almost every Raider knows how crucial the weapon blueprints for Equalizer and Jupiter are to ARC Raiders.
These two weapons are arguably the core indicators of a player's or team's late-game maturity, possessing devastating power in PvE, especially against high-difficulty mechanical bosses in the late game, where they outperform regular ARCs. However, not all players possess them.
As high-value weapon blueprints, the primary way to obtain them in the game is still by farming Harvester Puzzle.

Harvester Puzzle
Spawn Points
Harvester Puzzle typically spawns as a limited-time map event for ARC Raiders, guarded by Queen.
Its main spawn maps are:
- Dam Battlegrounds
- Spaceport
- Blue Gate
Of course, you can check the icon in Speranza lobby map interface to see where it lights up. Harvester Puzzle lasts for about an hour, after which it transitions to the next environment, so it's recommended to go there immediately after checking the icon's location.
Key Features
Harvester Puzzle revolves around speed and puzzle-solving, with a continuous 45-second cycle (charging, discharging, fire-breathing), severely testing players' speedrunning abilities.
Therefore, your task isn't to defeat Queen outside, but to quickly infiltrate the interior and solve the puzzles.
Completion Guide
1. Collect and Insert Power Canisters
After entering, use the elevator to reach the upper area. You'll need to use melee attacks or shooting to forcefully break through the upper metal panels to find hidden Power Canisters(3 are needed; sometimes one is lying on the ground).
The facility's high-temperature defense system will activate periodically (the interior will glow orange or blue). When the system activates, you must immediately find cover or temporarily leave to avoid being burned by the flames.
Blue light indicates an impending EMP impact, which only breaks the shield without causing damage (you can remove the shield to become immune to damage).
A flashing orange and red light accompanied by a rapid alarm indicates that a full-scale firestorm will occur in 3 seconds, instantly burning your character to death. You must immediately escape the cabin for safety.
After successfully escaping, forcibly break open the slot at the bottom of the central pillar (Queen will release a brief stun current upon breaking it; it is recommended to remove your shield beforehand to prevent it from shattering). Insert all 3 collected Power Canisters into the connected terminal.
2. Destroy the Yellow Button
After inserting all Power Canisters, Harvester will completely shut down, and 3 separate reward containers will pop up around the central pillar. Opening these containers will give you a chance to obtain high-tier loot and the extremely rare weapon blueprints for ARC Raiders Jupiter, and Equalizer.
To prevent enemy players from ambushing you outside, it is recommended that you immediately place the blueprints into a Safe Pocket and quickly head to the extraction point after obtaining them.
Weapon Configurations
Targeting the characteristics of Harvester Puzzle and for a safer extraction, here are two optimal weapon configurations after ARC Raiders 1.38.0 update. These configurations feature high burst damage, rapid shield breaking, and node-breaking kills, allowing you to more safely obtain Jupiter and Equalizer.
First Configuration
Primary Weapon: Renegade
Renegade is the primary damage-dealing weapon, effectively dealing with Queen guarding the outside and large numbers of ARC robots. Its high single-shot damage and accuracy allow you to quickly clear the area before entering Harvester.
Secondary Weapon: Stitcher
Stitcher is primarily used for melee combat and emergency shield breaking, suitable for defense and quickly breaking shields in the event of sudden external conflicts.
Second Configuration
Primary Weapon: Renegade
Same function as the first configuration, but easier to obtain and more suitable than other ARC Raiders Weapons with similar functions.
Secondary Weapon: Scambler
After planting all Power Canisters in the first step of Harvester Puzzle, a yellow node will pop up on the central pillar. Using Scambler at close range, you can kill a node in just two shots, making it faster and less strenuous.
Besides weapons, there are some essential items that you should carry regardless of your build:
Crowbar
Used for quickly prying open vents to infiltrate and for prying open second-floor panels to retrieve Power Canisters.
Surge Coil
While prying or planting Power Canister, place it at the only main entrance and vents on the first floor of Harvester to effectively prevent other Raider teams from sneaking in and attacking.
While regular safe pockets usually have restrictions on what items can be put in, ARC Raiders Looting Mk. 3 (Safekeeper) not only allows you to put in any item in the game, but you can also take the items out even if you are knocked down.
Therefore, after completing Harvester Puzzle and obtaining Jupiter and Equalizer weapon blueprints, place them along with your primary weapon into Safe Pocket provided by Looting Mk. 3 (Safekeeper) to prevent them from being stolen.
Since a Harvester Puzzle only rewards three chests, and only one Jupiter or Equalizer blueprint will appear at a time, if you are in a multiplayer group, only one person can obtain the blueprint. The player who doesn't get it needs to re-enter and try again.
Therefore, some players prefer to operate solo, making the three ARC Raiders Items mentioned above essential. In addition, there are some tips suitable for solo players, the essence of which lies in avoiding combat, removing the shield, speed, and quick escape through tunnels.
Tips
1. Removing the Shield for Infiltration
Observe the patrol routes of ARC Queen on the outer perimeter. The instant you enter the facility's main gate or ventilation shaft, immediately manually remove your shield from your inventory. This perfectly negates the severe stun and vulnerability caused by the pulse shield breaking.
2. Quickly Transport Power Canisters
After entering the first floor and picking up the canister in its designated location, quickly insert it. Then, take the elevator directly to the second floor and find the remaining two Power Canisters. Don't carry them up the stairs; throw them directly to the first floor.
If you hear three alarms or the sealed compartment lights up with an orange-red light, don't hesitate; run.
3. Instantly Eliminate Alarm Nodes
Use ARC Raiders shotgun recommended in your weapon configuration. Run and fire simultaneously; you can clear the nodes in about three seconds.
4. Instant Escape Through the Tunnel
After solving the puzzle, open the two chests closest to you in the center. With luck, you might find the blueprint for either Jupiter or Equalizer. Once you find them, immediately put them in your Safe Pocket. Don't linger in the red zone; quickly move to the nearest Raider Hatch to escape.
If your strength and time allow, you can also try defeating Queen outside, as it, being a high-level boss, has a chance to directly drop the blueprints for these two legendary weapons. Even without the blueprints, it will drop the rare material needed to craft these weapons - Queen Reactors.
In short, if you want to quickly acquire the blueprints for Jupiter and Equalizer, or already own them but want to farm more for trading on the market, ARC Raiders Harvester Puzzle is your best choice.
