The ARC Raiders Jupiter Blueprint is a special reward from the Harvester map condition, not an ordinary Raider Cache drop. Visit a Harvester, complete its three-fusion-core puzzle and search the revealed reward containers. Once learned, the recipe creates the Legendary Jupiter sniper at Gunsmith Level 3 with 3 Magnetic Accelerators, 3 Complex Gun Parts and 1 Queen Reactor.
Harvester is one of the most dangerous activities in ARC Raiders because a Queen protects the structure outside. The key detail is where the schematic comes from: the Harvester’s special puzzle loot, not a guaranteed drop from killing the Queen. The Harvester steps, Gunsmith ingredients and current Jupiter stats are below.
ARC Raiders Jupiter Blueprint location and Harvester conditions
| Requirement | Where or how |
|---|---|
| Blueprint source | Harvester puzzle loot containers |
| Map condition | Harvester on Dam Battlegrounds, Spaceport or The Blue Gate |
| Drop type | Random special loot, not a guaranteed reward |
| Crafting station | Gunsmith Level 3 |
| Materials | 3 Magnetic Accelerators, 3 Complex Gun Parts, 1 Queen Reactor |
The ARC Raiders Jupiter Blueprint shares its Harvester reward source with the Equalizer Blueprint. Either schematic can appear in the condition’s special containers. Completing the Harvester puzzle opens the chance to loot them; it doesn’t force a particular legendary recipe into your backpack.
How to unlock the Harvester puzzle loot
- Queue into an active Harvester map condition and locate the large machine guarded by the Queen.
- Reach the Harvester interior without standing in the Queen’s line of fire.
- Breach the accessible upper-level containers and collect fusion cores. One additional core can appear on the central floor.
- Bring three fusion cores to the central pillar.
- Insert all three fusion cores into the central pillar in quick succession.
- Destroy all 12 glowing yellow targets that appear inside the Harvester after inserting the cores.
- Search the opened reward containers for Jupiter or Equalizer blueprints and ARC materials.
- Protect a found blueprint in your Safe Pocket and extract safely.
The ARC Raiders Jupiter Blueprint is not a reward from every Harvester activation. The ARC Raiders Jupiter Blueprint remains part of a random loot pool after all 12 targets are destroyed. Bring enough healing and ammunition to survive the trip, and move carefully when the Queen is nearby. A Harvester structure is a different event from Pendola Pass’s Redirection Harvester Payloads.
How to craft the Jupiter sniper rifle
Learn the ARC Raiders Jupiter Blueprint by choosing Learn and Consume in Speranza. Then visit Gunsmith Level 3. Supply three Magnetic Accelerators, three Complex Gun Parts and a Queen Reactor to make the Jupiter. The Queen Reactor comes from the Queen encounter and is a crafting ingredient, not the blueprint itself.
| Crafting item | Amount |
|---|---|
| Jupiter Blueprint | Learn once |
| Magnetic Accelerator | 3 |
| Complex Gun Parts | 3 |
| Queen Reactor | 1 |
| Jupiter result | One Legendary sniper rifle |
You need the learned recipe and all seven material pieces. The Jupiter uses Energy Clips rather than Heavy or Medium Ammo. It cannot be upgraded through the usual I–IV weapon tiers, so don’t look for Jupiter II, III or IV recipes in the Gunsmith.
Jupiter damage and recent Frozen Trail change
Jupiter is a bolt-action sniper with a five-round magazine, strong armour penetration and a base damage stat of 60. Embark’s 2.0 patch corrected damage propagating twice to ARC parts behind the target; the result is stronger performance against armour but slightly weaker performance against some weak points.
The ARC Raiders Jupiter Blueprint remains worthwhile because learning it turns a rare special-condition reward into a repeatable craft, although the Queen Reactor remains a significant part of the resource cost. In 2.0, Jupiter also supports fifth-quality Amplification after Level 4 station progression, using a Mk. V module and its own upgrade research.
What to do when the blueprint doesn’t appear
If the special loot gives you an Equalizer or crafting materials instead, you’ve still completed the event correctly. The ARC Raiders Jupiter Blueprint isn’t guaranteed on a fixed run. Look for another Harvester window rather than farming normal Residential or Raider Containers expecting the same exclusive item.
A completed Jupiter weapon can also come from the Trophy Display project reward, but obtaining the finished rifle isn’t the same as learning its crafting recipe. Save the ARC Raiders Jupiter Blueprint once it appears and learn it back in Speranza so future crafts only need the Gunsmith materials.
