Icarus Update 235 Adds Deep Cycler and Obsidian Veins
Icarus Week 235 introduces the Tier 5 Deep Cycler for reconfiguring deep ore deposits and brings Obsidian veins to all maps. The update also adjusts creature behaviors, fixes building placement helpers, and optimizes textures.
Week 235 arrives in Icarus with new end-game resource tools and map-wide updates. This patch expands Obsidian availability across Olympus, Styx, and Elysium, and introduces the Tier 5 Deep Cycler to let prospectors manage and reconfigure deep mining operations on existing saves.
Deep Cycler and Resource Management
The Tier 5 Deep Cycler is crafted at the Manufacturer and powered by Refined Oil. Placed on the terrain, it reconfigures nearby Deep Ore Veins into different available resources. Veins with active drills attached are excluded, and all affected deposits appear in the UI before activation. Activating the device attracts Caveworms and Landsharks, requiring players to defend it until the process completes. The Deep Cycler provides an opt-in solution for older prospects to generate newer resources like Obsidian without requiring a world reset.
Obsidian Deep Ore Veins
Obsidian Deep Ore Veins now spawn naturally on all newly created worlds across Olympus, Styx, and Elysium. Existing prospects require the use of the new Deep Cycler to generate the veins and access their associated technologies.
Creature Adjustments and Quality of Life
Lava Broodlings no longer attack and kill other creatures by default, a change implemented to keep volcanic biomes populated with active fauna. Basic building beam placement guide helpers now render correctly and are no longer squished. The Resource Network Inspector UI has been adjusted to prevent text overlapping across different languages. Additionally, roughly 500MB of billboard textures have been optimized down to 512px.
Why this patch matters
Week 235 solves a long-standing issue for veteran Icarus players by giving them control over resource generation on older maps while introducing new defense mechanics for deep mining.
