Icarus Week 223 Update Brings Lithium Workshop Pack and Hoverframe Adjustments

Icarus Week 223 introduces a Lithium Workshop pack requiring uranium rods, refines Hoverframe placement rules, and fixes power drain bugs on Tier 5 tools. The patch also adds a custom setting to protect mounts from unauthorized unclaiming.

Following the Dangerous Horizons expansion, the Week 223 update for Icarus focuses on mechanical clarity, resource availability across maps, and quality-of-life improvements for high-tier tools and vehicles.

Workshop and Resource Changes

The Raw Lithium Resource Pack is available in the Orbital Workshop, allowing players to utilize Tier 5 equipment on Olympus, Styx, Prometheus, or outposts. Purchasing these items requires Uranium Rods, necessitating prior exploration of Elysium. Packed Fuel Bricks now stack to 25 and hold 1.5 times the transmutable fuel value of coal.

Tool and Mount Fixes

Lithium tools have been fixed so that toggling them off halts power drain. The Lithium Axe power cost calculation now targets only additional resources rather than total wood generated, significantly extending battery life. A new custom world setting allows hosts to restrict mount unclaiming exclusively to the owner, preventing other players from unclaiming foreign mounts.

Hoverframe and Elysium Adjustments

Hoverframe deployment is more flexible on uneven terrain, and deploying the vehicle automatically claims it. Exit logic has been updated to prevent players from teleporting beneath the ground in tight spaces. The Orbital Exchange Interface messaging on Elysium has been revised to clarify options between reaching Eden or deploying an advanced landing pad.

Why this patch matters

This update makes late-game resources accessible across older maps while solving persistent friction points with hover vehicles and energy management.
