CNS in Stellar Blade mods usually means Custom Nanosuit System — a mod framework that lets modders add custom outfits and lets players switch between them in-game through a UI.

What it does

  • Adds support for custom nanosuits/outfits instead of only replacing a single base outfit.
  • Makes outfit switching easier through an in-game menu.
  • Is often used as a required base for other Stellar Blade clothing or appearance mods.

In plain English

Think of it as a mod loader for outfits : instead of each mod overwriting the same slot, CNS helps multiple cosmetic mods coexist more cleanly.

Common setup note

Some guides mention it works alongside UE4SS, and that certain outfit mods need their files arranged correctly for CNS to recognize them.

TL;DR: CNS = Custom Nanosuit System, a Stellar Blade mod framework for managing and swapping custom outfits.
