Icarus Week 202 Update Adds Ubis Mounts and Swamp Survival Talents
Icarus Week 202 introduces the tamer-focused Ubis mount with swamp survival talents, along with extensive audio and quest fixes across Elysium. The patch also previews upcoming 5.56mm CHAC workshop ammo for the next update.
The latest Icarus patch brings the giant Ubis mount from the swamp biome into the stable, alongside widespread bug fixes, quest logic adjustments, and audio updates for the Elysium region.
New Ubis Mount and Taming
Prospectors can now capture and raise Ubis mounts in the swamp biome. Juvenile Ubis spawn alongside adult creatures and can be claimed by defeating the parent. While slower than Moas, the Ubis supports standard Moa saddles and features a dedicated talent tree focused on swamp survival, poison resistance, and an attack-while-riding capability. Juvenile spawn rates, movement speed, and stats have received balancing adjustments.
Quest and World Progression Fixes
Several progression blockers on Elysium have been resolved. The Locate_Travel quest sphere now covers the entire entrance area to prevent missed triggers, and the second access door is locked behind a timer to sync with dialogue events. Mission four and five dialogue interactions, dropship crash sequences, and landing pad logic for non-open-world missions are now functioning correctly.
Audio and Radiation Adjustments
Radiation mechanics now feature updated geiger counter audio, improved modifier state sounds, and a progress bar spanning the three radiation phases. Ambient soundscapes across the Tundra and Elysium biomes have been rebalanced to reduce bird and insect volume during storms. Numerous creature audio events, including idle layers for hoppers and footsteps for chews, have been added or tweaked.
Why this patch matters
Week 202 delivers a combat-oriented mount alongside critical bug fixes for Elysium missions, rounding out the experience ahead of upcoming workshop additions.
