Icarus Week 201 Update Introduces Aquatica Isle and Cultivar Backpack
Icarus Week 201 adds the Aquatica Isle Outpost DLC and the farming-focused Cultivar Backpack to the orbital workshop. The patch also brings AI perception changes, radiation system updates, and extensive bug fixes.
Icarus Week 201 brings the coastal Aquatica Isle Outpost DLC alongside the seed-collecting Cultivar Backpack and a suite of technical fixes for AI behavior and world interactions.
Cultivar Backpack and Workshop Additions
The Orbital Workshop now features the Cultivar Backpack, designed for agricultural efficiency. Available for research using 250 Ren and 500 Exotics, and craftable for 100 Ren and 250 Exotics, the backpack allows players to collect seeds directly while harvesting. It provides six extra inventory slots and increases harvesting yields, reducing the need for specialized seed extraction tools.
Aquatica Isle Outpost
A new coastal outpost DLC, Aquatica Isle, is now available. Modeled after Motuihe Island in New Zealand, the map introduces coastal terrain, custom foliage, and new material layering. The area is available as a standalone purchase or bundled with existing outposts.
AI and Combat Adjustments
AI damage perception events now persist for 10 seconds instead of three, preventing enemies from dropping combat states prematurely when attacked from outside visual range. Giant Roach creatures receive unique behaviors that trigger when targets are within 35 meters, alongside new audio cues, locomotion blending, and adjusted capsule collisions.
Radiation and World Systems
Radiation mechanics have been expanded with medium and heavy radiation events, geiger counter audio, and a three-phase progress bar in the UI. Mange wolves now appear in irradiated enemy spawn pools, and squad-based follower AI will share perception events with nearby allies when attacked.
Why this patch matters
Week 201 streamlines agricultural workflows with a specialized backpack and expands building options with a coastal outpost, supported by deeper AI awareness mechanics.
