Icarus Update Adds Hammerhead Slug World Boss
Hunt the new Hammerhead Slug world boss in Prometheus swamps. The update also optimizes assets and tweaks creature combat.
The Week 165 update introduces a world boss to the swamps of Icarus alongside performance optimizations and audio adjustments.
Hammerhead Slug World Boss
The Hammerhead Slug spawns in all swamp regions of the Prometheus map. When it takes sufficient damage, the boss splits twice into smaller targets that attempt to recombine over time. The boss carcass highlights clearly, and its poison modifier applies a 50 percent sprint speed reduction instead of a 5 percent movement speed penalty.
Creature Adjustments and Spawns
Black Wolf spawn points are added to Olympus arctic areas, and boss spawn zones shift away from starting regions. Rock Golem rolling attacks push targets to the side rather than straight forward, and juvenile rock golems receive fixed locomotion animations and added armor.
Performance and Asset Optimizations
A project-wide asset optimization pass reduces texture sizes and memory usage. Obsidian pickaxes and sickles receive physics asset updates and texture reductions.
UI and Audio Improvements
Great Hunt interfaces receive tracking updates and new respawn timers for world bosses. Audio adjustments reduce volume spikes on waterfall assets and increase dialogue clarity during storms.
Why this patch matters
Week 165 adds a world boss to the swamp biomes while delivering foundational cleanup and UI improvements.
