Icarus Week 205 Update | Stone Brick Fireplace and New Biome Preview

Posted by Heightmare on

Welcome to Week 205.

This week, we're adding a new Stone Brick Fireplace to match your Stone Brick houses, giving your builds a bit more charm and detail.

We're also sharing a first look at a new biome on an upcoming map: the Geothermal Biome. It brings some unique landscapes and features that we think you'll enjoy exploring.

Next week, we'll be introducing a new Grenade Variant, adding another combat option for surviving on Icarus

Notable Improvements:

  • Fixed issue where Stalkers would drastically increase in size when shot with projectiles while fighting.
  • Fixing issues where tooltips in the tech tree where not showing the resources required for the recipe (such as milk, biofuel and water).
  • Increased Fur drop on Tusker to match the amount it should be dropping, giving its position within the biomes and spawn group.


This Week: New Stone Brick Fireplace


This week, we're introducing a new Tier 3 unlockable item: the Stone Brick Fireplace. Crafted at the Advanced Masonry Bench, it’s designed to perfectly match your Stone Brick building pieces, adding both function and style to your builds.

The Stone Brick Fireplace is a wood-burning counterpart to the Biofuel Fireplace. It provides the same cooking speed bonus, while offering a different aesthetic for those who prefer a more classic or rustic look. Whether you're furnishing a cozy home or upgrading your settlement, this fireplace gives you another way to make your spaces feel lived-in and unique.



Upcoming Biome: Geothermal


As we mentioned last week, we are working hard on our next major expansion alongside our usual weekly updates, but we wanted to show you some backstage content as we work on it.



This week, we’re excited to give you a closer look at one of the major new features: the Geothermal Biome. This unique environment features large sulfur pools, treacherous crevasses, and a steam filled atmosphere, offering new challenges and gameplay opportunities.



The biome also introduces a variety of new resources and a host of creatures adapted to this extreme environment, providing fresh encounters and challenges for explorers.



Next Week: Impact Frag Grenade


We are adding something small but deadly next week - the impact frag grenade. This is a new grenade that explodes on impact instead of after a set amount of time providing a new way damage your foes. Be sure to check it out next week.



Your support makes these updates possible.
