Synthesized Fuel is a rare, Exodus-tagged material that gates explosive crafting. It’s required for the Explosives Station upgrade in the Workshop and is often the component that slows progress. The recipe calls for 3x Synthesized Fuel, 5x Crude Explosives, and 5x Pop Trigger.

Beyond the upgrade, each fuel unit can be recycled into 1x Oil and 1x Plastic Parts, and it doubles as a throwable that detonates for 80 damage in a 7.5m radius when shot.

Where to buy Synthesized Fuel (Celeste in Speranza)

The most dependable path is trading with Celeste, Speranza’s faction leader. Her offer unlocks at level 12 and the price is fixed: 14 Assorted Seeds per Synthesized Fuel. Seeds pile up through routine play — completing faction missions, looting generic containers, and trading surplus materials with other faction leaders.

Tip: Start banking seeds early so you can immediately convert them once you hit level 12.

Best location to farm Synthesized Fuel (Spaceport Rocket Assembly)

If you prefer to loot it, head for Rocket Assembly on the Spaceport map. The area carries the Exodus environmental tag, matching the item’s classification and improving your odds.

  • Check large rocket component structures with open hatches.
  • Search industrial containers near platforms and generator units.
  • Climb to elevated platforms via ladders or ziplines; high spots often hide single spawns.
Warning: Spaceport is high-traffic. Expect competition and plan extraction accordingly; going during off-peak hours reduces risk.

Recycle Rocket Thruster into Synthesized Fuel

Rocket Thruster is an Exodus-tagged drop that frequently appears around Rocket Assembly. Recycle one to receive 2x Synthesized Fuel and 6x Metal Parts — the most efficient conversion if you’re specifically chasing fuel.

Combat use of Synthesized Fuel (throw and detonate)

Fuel canisters serve as on-demand explosives. Throw a unit into enemy cover and shoot it on the way down or after it lands. Time the shot to overlap multiple targets and use terrain to funnel enemies into the blast radius.

Tip: Reserve a single unit for emergency area denial during contested extractions.

Inventory and storage priorities (keep vs. sell)

  • Keep it if you still need the Explosives Station upgrade, you’re nearing level 12 to unlock Celeste’s trade, or you’ve got weight/slots to spare.
  • Consider selling if the upgrade is already done, you urgently need credits, or stash space is constrained.

Efficient farming rotation for Synthesized Fuel

  1. Knock out daily faction missions to build a consistent seed reserve.
  2. Run quick Spaceport raids that beeline for Rocket Assembly; loot and exit.
  3. Trade accumulated seeds with Celeste for guaranteed fuel units.
  4. Immediately recycle any Rocket Thrusters you find to double up on fuel.

Backup strategies and resource routing

  • Damaged component recycling: Degraded ARC items sometimes break into materials that support your crafting chain, indirectly protecting your fuel supply.
  • Credit generation: Bastion Cells and ARC Coolant carry strong sell values (around 5,000 and 1,000 credits). Converting these can fund your next batch of fuel via seeds.
  • Workshop efficiency: Advanced ARC Powercells can be broken down into 2x ARC Powercells. Lean on those for power needs so fuel can go toward explosives instead of being tied up in other projects.

At a glance: best ways to get Synthesized Fuel

Method Requirement Yield / Cost Risk / Notes
Buy from Celeste (Speranza) Level 12 unlock 14 Assorted Seeds per 1x Most reliable; build a seed bank early
Loot Rocket Assembly (Spaceport) Exodus-tagged area Random spawns High player traffic; plan fast extractions
Recycle Rocket Thruster Find in Rocket Assembly 2x Fuel + 6x Metal Parts Best single-action fuel yield

Treat Synthesized Fuel as both a progression bottleneck and a tactical tool. Rotate Spaceport runs with steady seed farming, convert Rocket Thrusters on sight, and only recycle or sell fuel when your Workshop plan is covered. That mix keeps you stocked for the Explosives Station upgrade and leaves enough on hand for the moments that decide extractions.
