arc raiders explosive station upgrade

NOaHGray574

In extraction shooters like ARC Raiders, controlling the battlefield through raw firepower is one of the most effective ways to survive a raid. While having a solid rifle is essential, leveling up your Explosives Station at Speranza is what transforms you from a vulnerable raider into a true high-damage powerhouse.

Upgrading this station unlocks highly effective zoning tools, fire-based weapons, and massive area-of-effect (AoE) gear that can stop aggressive ARC bots—or hostile raiders—right in their tracks.

Here is a complete breakdown of what it takes to upgrade your Explosives Station from Level 1 to Level 3, how to farm the required resources efficiently, and the strategies that will save you time in the field.

Upgrade Costs and Unlocks

The Explosives Station scales across three levels, each requiring a mix of common scavenger loot and high-tier parts stripped directly from defeated ARC machinery.

Before diving into the grind, here is an important tip: prioritize upgrading your Refiner Station to Level 2 first. A Level 1 Refiner allows you to turn 6 Chemicals into Crude Explosives directly at your base, meaning you won’t have to rely entirely on finding them top-side. Once you hit Refiner Level 2, you can even craft advanced Explosive Compounds using 2x Crude Explosives and 2x Oil, drastically lowering the RNG required for your Level 3 upgrades.

Best Material Farming Routes & Pro-Tips

Hunting for these items without a clear plan will result in lost gear and frustrating runs. To hit your upgrade targets efficiently, focus your raids on specific maps and areas.

If you want to bypass part of the blueprint grind and fast-track your workshop capability, you can look for outside trading options like U4N to buy arc raiders blueprint bundles, which lets you jump straight into crafting once your station levels are met.

Level 1 Materials: The Baseline Grind

• 50x Chemicals: These are everywhere. Check residential cabinets, industrial crates, or simply buy them directly from Celeste back at base when her inventory refreshes.
• 6x ARC Alloy: Salvaged from the wrecks of basic ARC bots and ruined mechanical husks. Clear out minor patrol clusters on any map to stack these up quickly.
  
  

Level 2 Materials: Fuel and Fuzes

• Synthesized Fuel: Head over to the Spaceport map and carefully scavenge the vehicle bays and machinery within the Rocket Assembly area. Alternatively, load into the Dam Battlegrounds map and track the main road running between the Electrical Substation and the South Swamp Outpost—there are several fuel trucks parked along this route that regularly yield fuel.
• Pop Triggers & Crude Explosives: Look for "Pops" and "Fireballs" (the rolling explosive drones that try to rush you). Defeating them drops these items. The interior lockers and elevated industrial catwalks inside the Rocket Assembly room at Spaceport are absolute hotspots for these spawns.
  
  

Level 3 Materials: High-Tier Engineering

• Laboratory Reagents: Do not look for these in industrial areas. Instead, head to the Buried City map. Navigate to the Piazza Arburto sector and locate the Pharmacy; the interior shelves here have a high spawn rate for medical and scientific reagents.
• Explosive Compound: While you can craft these at a Level 2 Refiner, you can also hunt for them in the field. Hit the Hydroponic Complex or the Water Treatment Center. Additionally, look out for the Electromagnetic Storm map event—fossilized lightning left behind in the sand after strikes can be recycled into 3x Explosive Compounds each. You can also buy up to 3 Firework Boxes a day from vendors to recycle them down into 1 Compound apiece.
• 3x Rocketeer Drivers: These only drop from elite Rocketeer ARC units. To farm them safely, bring heavy-impact weapons capable of dealing massive structural damage, such as the Showstopper or the Deadline. Stun the Rocketeer first to interrupt its barrage, crack its armor, and secure the drop.
  
  

By focusing on one tier at a time and hitting these high-yield drop zones, you can fully max out your Explosives Station in just a handful of calculated raids.
