Mission read

Create chemical compound as guided, deploy and observe. Run it as a mission prospect on Prometheus with a recorded difficulty of 1/4. Time allowance: 3d; payout: Easy 150 Ren + 75 Stabilized Exotics; Normal 300 Ren + 150 Stabilized Exotics; Hard 450 Ren + 225 Stabilized Exotics

Campaign position

• Prerequisite: Ashlands
• Unlocks: Lava Hunter Volcanic Module

Where to go

Objective approach

No per-difficulty item manifest is recorded for this guide. Follow the on-screen tracker, then use the notes below to decide what to stage before committing to the final hand-in.

• Read the objective tracker after every major interaction; many ICARUS prospects reveal the next step only after the current one completes.
• Stage resources at the hand-in or build site before triggering final timers, wildlife waves, or extraction travel.
• If the guide has a manifest above, build the Hard list first when possible; it covers lower-difficulty planning and avoids under-packing.
• Keep the return route open. A finished objective still fails the run if the crew cannot safely reach the dropship or delivery pod.

Preparation

• Start with a bedroll, campfire or shelter kit, oxygen and water storage, bandages, splints, and enough food to cover the full route.
• Assign one player to navigation and one to resource accounting so the crew does not duplicate long hauls or miss a delivery line.
• Use the loadout list below as the minimum kit, then add mission-specific tools before launch.

Hazards and controls

• Severe weather / storms.: plan a countermeasure before leaving the initial safe zone; do not wait until the tracker sends you across-map.

Execution checklist

• Before drop: confirm prerequisite unlocks, mission timer, loadout, and who carries shared deployables.
• On landing: locate water, set a respawn point, and confirm the first objective marker before building a permanent base.
• Mid-run: consolidate loot and mission items at one marked cache; keep one repair kit and medical stack on each player.
• Before extract: verify every optional delivery, reward unlock, and follow-up objective is complete before leaving orbit-side cargo behind.
