In Arc Raiders, getting your hands on the best gear can be the difference between scraping through a fight and dominating the battlefield. Most folks spend hours grinding missions with no guarantee of decent drops, but there’s a sneaky way to hit the jackpot. It all starts with a trip into the wild to hunt for the ARC Raiders Items you’ll need — specifically, the Encrypted Keycard. This rare bit of kit only comes from taking down Elite Sentinel drones. These aren’t your average patrol bots; they’re tougher, heavily armoured, and pack plasma repeaters plus an EMP blast that’ll fry your gadgets. You’ll usually find them around high-value spots like the wrecked capital ship or the fortified comms array. If your squad works together, you can farm a bunch in one run, upping your odds of grabbing that keycard fast.
  Once you’ve got the keycard, the real fun begins. The vault is hidden deep under the X-ION Research Facility — a place most players barely scratch the surface of. To get in, you’ll need to knock out its layered security in the right order. First up, there are three external generators powering the vault door. Each one’s tucked inside a reinforced bunker with turrets and roaming AI guards. You’ll need to split the squad and hit all three at pretty much the same time. Mess up the timing and you’ll trigger lockdown, which means more elite enemies swarming in and your chances of getting inside drop to near zero.
  With the power cut, you can finally get to the main blast door. Slot the keycard into the console and you’ll be faced with a timed puzzle. It’s all about rerouting power through different nodes, and you’ll need at least two players working separate terminals while calling out instructions. Miss a step and the whole thing resets, so communication here is key. This part catches a lot of teams off guard — it’s not just about shooting, it’s about thinking fast under pressure.
  Crack the puzzle and you’re in. The vault’s a treasure room stacked with sealed weapon crates holding rare or epic guns, often with custom attachments you won’t find anywhere else. There are gear lockers stuffed with advanced armour and tactical gadgets. But the real prize is the Fuel Rod stash — several large containers full of these high-value materials, perfect for crafting and upgrades. The moment you start looting, every AI unit in the area will know where you are. The extraction run is brutal, with waves of enemies trying to pin you down. Use the new gear you’ve just picked up, move fast, and don’t waste time. If you make it out, you’ll walk away with more loot than most players see in a week, including some of the finest ARC Raiders weapons you can get.
