Icarus Update Adds In-World Fish, Server Browser Overhaul, and Rad Boss Balance
Icarus update 3.0.22.155681 brings in-world fish matching local waters, graduates the Dedicated Server Browser out of beta, and rebalances the Rad Boss encounter.
Icarus version 3.0.22.155681 expands planetary wildlife with diverse aquatic ecosystems, brings the dedicated server browser out of beta, and applies extensive adjustments to boss fights, missions, and gear.
Ecosystem and Fishing Additions
Waterways now feature all 20 fish species alongside three variations each, totaling roughly 70 unique swimming fish that reflect local fishing pools. Players can craft the new T3 Carbon Fiber Fishing Rod at the Fishing Bench to catch them. The update also introduces early asset implementations for Beavers and Giant Turtles.
Dedicated Server Browser Upgrades
The Dedicated Server Browser exits beta with upgraded reliability. Applying search filters while the browser discovers servers will no longer return mismatched results, and peer-to-peer servers will no longer appear twice. The Matching Version filter is enabled by default, and a rotating loading indicator appears during refreshes.
Rad Boss Encounter Rebalance
The Rad Boss receives balance adjustments, including base health changing to 60k with a +50% per-player health scaling on medium difficulty. Radiation sickness mechanics are restructured: its spit and upright-phase heavy slams apply guaranteed radiation sickness, while normal attacks no longer possess random chance triggers. Its melee damage rises to 300 and laser resistance drops to -33%.
Mission and World Fixes
Livewire mission blockers, such as wolf pack triggers breaking progression and wolf dens spawning on every reload, are corrected. Fission and faction spawners no longer default to destroyed states on reload. Explosive resistance stats display as flat percentages, and the Double XP event banner is removed.
Why this patch matters
This update addresses long-standing server reliability issues while overhauling aquatic immersion, mission stability, and endgame boss parameters.
