Icarus Week 233 Update | Timber Extraction Unit Notes (22nd May 2026)

Welcome to Week 233.

This week marks the launch of the Timber Extraction Unit, a brand-new Legendary item purchasable from the Biolab. Designed for high-efficiency harvesting, this powerful tool can rapidly decimate forests while also doubling as a dangerous weapon, launching spinning saw blades at unsuspecting creatures.

Elysium has also received a small map update in preparation for future content, with a new structure now appearing in the Western Volcanic Region.

We’re also giving a small preview of what’s arriving next week: interior wood curved floors and curved railings, expanding building customization options even further.

Notable Improvements:

• Optimized several dozen common (creatures + environment) Niagara effects, reducing load on CPU/GameThread. Reduced spawn rate of wisp effects.
• Optimized MIP gen settings on over 2000 icons which should result in crisper looking icons and some resolution/compression optimizations. Added tooling to find icons with incorrect settings.
• Fixed Leech talent on Slinker and Skulk not working due to missing stat to define how much health to leech. Fixed missing title/description on Skulk talent tree.
• Fixing Savage Bloodline so it has the correct stat so creatures can leech life on hit
• Moved DLC and heavy item type icon from title bar pop up to main item pop up window
• Added LODs to plane used for water ripple effect. Prevent spawning water ripple effects unless actually tracing against water.

This Week: Timber Extraction Unit

This week brings a brand new Legendary item, the Timber Extraction Unit, a fully customizable circular saw with 12 unique alterations to select from to upgrade the Motor, Handle, Blade and Drive sections. This allows it to be specialized into making wood collection a breeze and to become a formidable weapon against your enemies.

Powered by Refined Oil, the TEU is capable of ripping entire forests to shreds in minutes. Upgrades such as the 'Refined Drive' will automatically award you with Refined Wood, or the 'Skinning Motor' allows for the skinning of creatures, or the 'Serrated Blade' causing increased hardpoint damage and applying Bleed, or the 'Expanded Motor' automatically picking up chopped wood to allow you to repurpose those critical character talent points. There's a nice variety of useful upgrades to customize the TEU to be your own.

While originally we had it as an optional upgrade, we decided the ability to fire the saw blades as projectiles was too fun to not make it a default function of the item. The TEU doesn't come with a Sawblade built in, they can be crafted on planet with just a handful of Iron Ingots, or for those who really want to hit the ground running, a Sawblade Workshop Bundle is available for purchase and immediate use. The TEU is available for purchase in the Bio-lab and requires 1x Legendary Licence.

This Week: Elysium Map Adjustment

This week in the Western Volcanic Region, a new area has been sealed off. Previously marked as unbuildable terrain, the location is now blocked by a newly appeared structure, preventing further access.

This change is tied to future content planned for the Elysium map. At the moment, the area has no interactions or gameplay functionality.

Next Week: Curved Interior Wood & Railings

Next week we are planning on adding an addition to the interior wood set - the curved floor pieces. As well as new curved wood railing which will snap to all curved floor pieces.
