Icarus Week 181 Update Introduces Tier 3 Biofuel Fireplace

Week 181 brings the new Tier 3 Biofuel Fireplace to Icarus, offering 20 percent faster cooking and the Warm and Cozy buff. The update also improves sign usage, quest objective readability, and prebuilt structure load orders.

The latest Icarus update adds a Tier 3 heating and cooking apparatus alongside a variety of quality-of-life adjustments and bug fixes across existing quests.

Biofuel Fireplace

Unlocked at Tier 3 and crafted at the Machining Bench or Fabricator, the Biofuel Fireplace requires Cement Mix, Epoxy, Iron and Steel Ingots, and Steel Screws. A full Biofuel can runs for 2 hours and 46 minutes. It cooks recipes 20 percent faster than the standard fireplace, grants 12 coziness, and applies the Warm and Cozy buff to improve sleep and daytime stats.

Interface and Readability

Quest objectives with numbers now display those numbers in a distinct color for better readability. Field guide menus feature new tabs at the top for faster navigation. Arrow images are now available for placement on signs.

World and Structure Fixes

Many prebuilt structures in quests have updated load orders so power and water networks hook up correctly. Bespoke assets from the Mission POTSHOT clean up as intended upon completion. Swimming animations no longer cause fingers to bend backward.

Why this patch matters

This update provides an efficient mid-game cooking and heating option while cleaning up persistent network and UI annoyances.
