Jupiter in ARC Raiders is a late‑game railgun for patient snipers, punching through ARC armor, deleting drones, and rewarding smart positioning, clean headshots, and disciplined long‑range control.
If armored units in ARC Raiders keep shrugging off your rifle like you are firing paintballs, then it is probably time to look at the Jupiter railgun instead of just farming basic gear, and as a professional platform to like buy game currency or items in U4GM that makes gearing up a lot easier, you can head over and pick up U4GM ARC Raiders to smooth out that grind.
What It Takes To Unlock Jupiter
You do not just walk into Speranza and buy Jupiter off a rack. You have to hit Pilot Level 35 before the Advanced Workbench even unlocks, and that alone filters out anyone who is only half‑committed. After that, you are stuck running the Railgun Prototype expedition chain, which is not exactly a quick trip. When that is done, the real work starts. You need 15 Exotic Energy Cells, which drop pretty reliably from Rocket Plant elites once you get into a good loop. Then you need 8 Nano‑Alloy Frames from Factory heavies, so expect a few messy runs there. The real pain is the 3 Quantum Capacitors. They only show up during Night Surge events, where everything hits harder and punishes bad positioning. On top of all that, the blueprint certification hits you for 250k coins, and later on you will notice the gun decays fast; around 200 shots and you are staring at a 50k repair bill if you want it fighting fit.
Stats, Feel, And Real Use Cases
Once Jupiter is built, it instantly feels different to your usual rifles. Each bolt hits for 55 damage with very strong ARC penetration, so armored targets start looking a lot less scary. Scout drones drop in a single clean shot, and Raptor armor tends to peel off in two if you are hitting core spots. The gun is not smooth to handle, though. It only carries 5 rounds in the mag, and the charge plus reload cycle sits around 3 to 4 seconds depending on how sharp you are between shots. It is heavy too, roughly 7 to 8kg in your loadout, so you cannot just carry every toy you want. On the flip side, the effective range is about 150m with scary accuracy, so you are often deleting targets that have not even fully spawned into your awareness yet.
Build Choices And Loadout Pairing
Running Jupiter stock is technically possible, but you will feel like you are always half a second late. Magnetic Accelerators are pretty much mandatory if you care about tempo, cutting the charge time by around twenty percent and making the gun feel a lot more responsive when things get messy. A Reinforced Barrel is also a solid pick, pushing penetration up so you can stay useful against the toughest armor in longer fights. Because the Jupiter is awful when enemies get right in your face, most players, me included, pair it with something like a Bobcat IV SMG for close‑quarters panic moments. A Grapple Hook rounds the setup out nicely so you can get to rooftops, cranes, or silo tops and control the approach instead of fighting on the ground where you are weaker.
Positioning, Target Priority, And Long‑Range Discipline
Jupiter rewards players who like to think two steps ahead rather than sprinting into every fight. You want height whenever you can get it: rooftops, catwalks, scaffolding, anything that lets you see armor columns and air units coming before they see you. Pop up, charge, fire a single shot, then drop back into cover; do not stand there admiring the hit. Flyers should usually be your first priority, because they expose your squad if you leave them buzzing around. After that, start cracking heavy cores and stripping armor so your teammates with more conventional guns can clean up. It is tempting to spam shots into any target you see, but Jupiter works best when you treat it like a precision tool rather than a general answer to everything, and if you are already using a service to like buy game currency or items in U4GM to speed up your setup, it also makes sense to look at specific gear like ARC Raiders iteams that help you lean fully into that long‑range, high‑impact playstyle.
