Icarus Week 223 lands
Icarus’ Week 223 patch adds Dangerous Horizons support — the update ships a Lithium Ore workshop resource pack, limestone building pieces, a fixed stone spikes recipe, and Elysium mission bugfixes Steam notes announcement. If you play survival crafting, the Lithium mod and recipe corrections are the headline changes that will affect late‑game crafting runs.
Week 223 was released March 13, 2026 as version v3.0.1.150228, the follow‑up patch posted on the official Steam news feed and recorded in the Icarus changelog. (store.steampowered.com) The update added a Workshop pack that supplies Lithium so Tier‑5 equipment can be crafted on maps that don’t contain Elysium resources, a change highlighted in the Steam announcement. (store.steampowered.com) Packed Fuel Bricks were buffed to provide 1.5× the transmutable fuel of coal and now stack up to 25, and limestone can be harvested using Stone or Iron pickaxes after the patch. (icarus.wiki.gg) RocketWerkz issued Week 223 one week after the Dangerous Horizons expansion (Dangerous Horizons launched March 5, 2026) as a rapid response to player reports from the new Elysium content and Kepler systems.
