Post
A post-clear difficulty ladder that makes victory unlock the sharper version of the game.
Boss cell systems gate harder rule sets behind major clears. They can add enemy density, reduce healing, open new routes, and change resource assumptions so the same game keeps mutating.
Example
Dead Cells uses Boss Stem Cells to reshape healing, biomes, enemies, and access to higher-end content after each major victory.
Why it matters
Boss cell difficulty matters because it turns a first clear into a curriculum instead of a finish line.
