Icarus received its Week 257 update on November 5, 2026, bringing a major rework to the Spelunking Operation in the Olympus Region. Version 3.0.35.159586 also includes a handful of bug fixes and a preview of upcoming content.
Spelunking Mission Rework
- The Spelunking Operation has been redesigned from the ground up. The heavy mining requirements have been reduced and replaced with more varied challenges.
- Players now discover a pre-existing mining hut and signs of past activity, including a fallen prospector and a caveworm, rather than arriving with no context.
- The rework removes the Workshop pickaxes that were previously granted as rewards, replacing them with on-world alternatives and reducing the total ore required to complete the operation.
- Higher-tier ores such as titanium and platinum have been removed from the cave and from delivery requirements, eliminating a common soft-lock.
- Silica and sulfur nodes have been added outside the cave so players always have access to the resources they need.
- Exotics are now discovered more organically during the operation rather than simply paid out as a flat completion reward.
- Quest markers, dialogue, objective text, and the pod spawn location have all been updated to match the new flow.

Bug Fixes
- Fixed caveworms, landsharks, and sandworms spawning at incorrect sizes.
- Fixed several typos and wording issues in quest text.
- Edited the carbon fishing rod item description to be less verbose.
- Corrected mission objective text in the Styx cave research mission to show the right order for powering up the analyzer.
- Improved clarity in the Courier Quest jump-start stage text.
Coming Next Week
- A new Workshop Battery Lantern is in development. Like the Workshop Flashlight, it will come pre-charged and ready to use.
