ARC Raiders players looking to add serious firepower to their arsenal now have a new target to chase. The Jupiter Railgun blueprint has become one of the most sought-after items in the game’s early access phase, and a fresh guide from NoobFeed breaks down exactly how to get it. If you’ve been grinding missions without a clear path, this walkthrough could save you hours of trial and error.

Why the Jupiter Railgun Is Worth the Grind

The Jupiter Railgun isn’t just another weapon attachment—it’s a game-changer for both PvE and PvP encounters. According to the guide, this blueprint unlocks a high-damage railgun that can pierce through enemy armor and deliver devastating single-shot blows. For players who prefer a calculated, long-range playstyle, this weapon offers a massive upgrade over the standard rifles and SMGs available early in the game.

What makes the blueprint particularly valuable is its rarity. Unlike common weapon parts that drop from regular loot crates, the Jupiter Railgun blueprint requires a specific set of steps and a bit of luck. The guide emphasizes that you’ll need to be at a certain level and have completed a series of story missions before the blueprint even becomes available in the world. This isn’t a casual pickup—it’s a reward for dedicated players who are willing to explore every corner of the map.

Blueprint Stats at a Glance

  • High base damage with armor-piercing rounds
  • Slower fire rate balanced by massive per-shot impact
  • Requires rare crafting materials to assemble
  • Best suited for medium-to-long range combat

Step-by-Step: How to Get the Jupiter Railgun Blueprint

The NoobFeed guide breaks the process into a clear sequence. First, you need to reach player level 25—this is the entry requirement for the mission chain that leads to the blueprint. If you’re below that, focus on side missions and bounty hunts to level up quickly. Once you hit the threshold, head to the main hub and speak with the weapons vendor to trigger the “Echoes of the Foundry” questline.

That questline will send you through three major zones: the Ashfall Expanse, the Silent Refinery, and the Underforge. Each zone contains a data pad that you must retrieve and decode. The guide warns that the Underforge is heavily guarded by elite robotic units, so bring a squad or at least a solid loadout with EMP grenades to disable the turrets.

After collecting all three data pads, return to the vendor and you’ll receive the blueprint as a quest reward. However, the guide also notes that the blueprint can occasionally drop from the final boss of the “Ruin’s Edge” raid, but that drop rate is extremely low—around 2% based on community reports. The questline is the reliable path, while the raid is a gamble for those who enjoy high-risk runs.

Pro Tips for a Faster Run

  • Team up with at least one player who has a repair tool to fix broken bridges in the Ashfall Expanse
  • Stock up on thermal charges to melt the ice barriers in the Silent Refinery
  • Use a sniper rifle for the Underforge’s long sightlines to pick off enemies before they close in
  • Don’t skip the optional side objective in the Refinery—it gives you a crafting cache with two of the rare components needed for the railgun itself

What to Do Once You Have the Blueprint

Getting the blueprint is only half the battle. To actually craft the Jupiter Railgun, you’ll need three titanium alloys, two flux capacitors, and one railgun core. The guide points out that these materials are scattered across the same zones you already explored, but they respawn on a daily timer. If you’re short on components, run the “Echoes of the Foundry” questline again—the data pad locations will also respawn, allowing you to farm the materials without extra risk.

Once crafted, the railgun requires a power cell to fire. These are common drops from shielded enemies, so you’ll never be completely out of ammo. However, the guide suggests carrying a backup weapon since the railgun’s reload time is long—around 4 seconds—which leaves you vulnerable in close-quarters combat.

The railgun also upgrades with blueprints found later in the game, so don’t think of this as a final weapon. It’s a strong mid-game addition that sets you up for the endgame content, where armored bosses become the norm. If you’re planning to tackle the “Ruin’s Edge” raid on hard difficulty, this railgun is almost mandatory for the final encounter.

Key Takeaways

The Jupiter Railgun blueprint is a must-have for any ARC Raiders player who wants to dominate both PvE and PvP modes. The questline is straightforward but requires patience, a good squad, and the right gear. Follow the steps above to secure the blueprint efficiently, and don’t forget to farm the materials before you attempt to craft the weapon. With this railgun in your hands, you’ll be a force to reckon with in the wastelands.

Remember: the blueprint is a quest reward, so don’t waste your time grinding the raid boss for a 2% drop chance. The reliable path is always the best path.
