Icarus Week 144 Update Introduces Arctic Vesper and Tooltip Overhauls
Week 144 for Icarus adds the dangerous Arctic Vesper to frozen biomes, dropping guano used for alternative biofuel and fertilizer recipes. The update also improves item tooltips to display precise resource capacities and removes obsolete recipes.
Icarus Week 144 expands the frozen expanses with a brand-new flying threat and quality-of-life adjustments for resource tracking and tooltips.
New Creature and Resources
Arctic Vespers now spawn in nests across frozen regions, attacking players who approach too closely at low altitude. Defeating them and looting their nests yields guano, a new resource used in alternate high-volume biofuel, volatile acid, and farm fertilizer recipes.
Tooltip and Crafting Adjustments
Item tooltips for water, biofuel, and electric charge now show current units and total capacity instead of generic stack counts. Crafting recipes that produce resources like water or biofuel now explicitly display output amounts. Additionally, the obsolete dirt mound recipe has been removed from the tech tree, with spent blueprint points refunded.
Audio and Fixes
Grenade throw animations and audio have been adjusted to fix missing visual cues and balance bounce sounds. Candle items have been updated to ensure flammable behaviors are consistent, preventing unintended fires.
Why this patch matters
Week 144 adds meaningful ambient variety to frozen biomes while delivering necessary clarity to tooltips and resource management.
