The Jupiter Blueprint is among the most coveted items in Arc Raiders, granting access to craft a powerful bolt-action sniper rifle with devastating damage and armor penetration. Obtaining this legendary blueprint requires completing one of the game's most challenging events and gathering high-tier crafting materials.
Finding the Harvester event on the map
The Harvester event spawns only at specific one-hour time slots throughout the day on Dam Battlegrounds and Acerra Spaceport maps. According to the current rotation schedule, Harvester events occur at these UTC times: 1:00-2:00, 9:00-10:00, 15:00-16:00, and 21:00-22:00.
Before queuing for a raid, check the map selection screen for the grey icon indicating which special event is currently active. On Dam Battlegrounds, the Harvester typically appears southeast of the Power Generation Complex near Red Lake. The event is protected by The Queen, a formidable world boss with extreme threat level and full armor plating

How to complete the Harvester event and obtain Jupiter Blueprint
Successfully completing the Harvester event requires careful planning, preparation, and execution. The event rewards three legendary blueprint containers upon completion.
Step 1
Locate the Harvester structure on the map during its active event window. Approach cautiously as The Queen patrols the area, along with other ARC enemies.
Step 2
Wait for The Queen to patrol away from the Harvester entrance with her back turned. Sprint quickly to one of the three identical breach doors and interact to open it. Avoiding combat with The Queen is the most practical strategy since defeating her isn't required to access the puzzle.

Step 3
Once inside, navigate the internal hazards. The Harvester launches probes every 45 seconds, igniting the interior in flames and opening three exhaust shutters. Time movements between launch sequences to avoid damage.

Step 4
Locate and collect three fusion cores scattered throughout the interior. Insert them into the center pillar quickly before the next launch sequence.

Step 5
After inserting all fusion cores, the Harvester releases electricity that stuns and drains shields.

Yellow nodes appear on the walls—12 in total. Destroy all yellow buttons by shooting or melee-ing them. Previously destroyed buttons won't reappear if the Harvester resets.
Step 6
Once all yellow nodes are destroyed, three loot containers drop from the central pillar. Each container typically holds one legendary blueprint—either Jupiter or Equalizer.


Step 7
Loot all containers and breach remaining panels on the upper ledge for additional resources.

Exit through the ventilation doors when The Queen faces away, then head immediately to the nearest extraction point or use a Raider's Hatch if carrying a key.

Unlocking the Jupiter Blueprint in your inventory
After successfully extracting with the Jupiter Blueprint, return to Speranza and access the inventory. Locate the blueprint item and select "Learn and Consume" to permanently unlock it for crafting. This action consumes the blueprint but adds the recipe to the Gunsmith station. Alternatively, duplicate blueprints can be sold for 5,000 coins if already unlocked.
Materials required for crafting Jupiter
| Material | Quantity | Source |
|---|---|---|
| Magnetic Accelerator | 3 | Dropped by The Queen, found in ARC debris, or recycled from Queen Reactor |
| Complex Gun Parts | 3 | Crafted at Refiner 3 using 1 Light Gun Parts + 1 Medium Gun Parts + 1 Heavy Gun Parts |
| Queen Reactor | 1 | Dropped exclusively by defeating The Queen boss |
Jupiter weapon performance

Once crafted, Jupiter delivers 421.85 DPS with a fire rate of 7.67 and strong ARC armor penetration. The weapon excels at long-range engagements where precision matters more than fire rate. Its 73.5 stability keeps shots accurate, though the 39.2 agility rating means slower handling compared to lighter rifles. The energy projectiles penetrate through enemies, making it effective against grouped targets.
However, the inability to attach suppressors means using Jupiter announces presence to nearby players and enemies. The bolt-action mechanism requires patience between shots, making it less forgiving than semi-automatic alternatives.
