Icarus Update 2.3.10 Adds 29 International Flags

Icarus Update 2.3.10 introduces 29 craftable international flags, adjusts creature health values across multiple biomes, and prepares upcoming content.

Update 2.3.10 for Icarus brings 29 new national flags for base decoration, creature health rebalancing, and foundational work for future patches.

International Flags

Players can craft 29 different international flags using the Decoration Bench at Tier 2 for a cost of 5 Steel Ingots and 5 Rope each. Flags feature three display variations including outdoor flagpoles, standing indoor versions, and wall-mounted options.

Creature Health Rebalancing

Base health values for numerous creatures have been adjusted. Raptor health changes from 1750-4500 to 750-2500, Stomper health moves from 300-700 to 900-2100, and Ghost Croc health shifts from 600-2200 to 2250-4500.

Crafting and Bench Fixes

An issue with the Glassworking bench where negative crafting speed modifiers failed to apply to water-based recipes during power brownouts has been resolved. Radiation Injection items now correctly heal radiation damage instead of applying it.

This update expands base customization options while laying out extensive creature stat revisions and bug fixes for crafting mechanics.
