Understanding Suit Module Slots
The Icarus exosuit features 6 primary slots: 2 for vital modules, 2 for utility, 1 shield, and 1 fabricator. Slots are color-coded by type, preventing mismatches. Base suits start with 4 slots; MK5 unlocks all 6 via workbench upgrades.
Modules consume power, so balance draw with generator capacity. 2026 patch added modular expansions, allowing +2 slots with rare schematics.
- Vital slots: Health, Stamina boosters
- Utility: Mining speed, stealth
- Shield: Damage absorption
