Earning a Boss Cell
Finish the final boss of a run and you can claim a Boss Cell. The next difficulty opens once you hold one.
You do not need to clear every difficulty in order. Each Boss Cell sets a harder baseline for the runs that follow.
What difficulty changes
Higher Boss Cells raise enemy health and damage. They also add tougher enemy types to biomes you already know.
Some Boss Cells change routes or gate extra content behind them. Unlockables gathered at low difficulty carry upward.
Manage the jump
Expect to die when you raise a cell. Learn the new enemies before you push for a clear.
Bank cells at the Collector before a hard attempt. Progress survives even when the run does not.
Play for a clear, not a record
On a fresh difficulty, survival beats speed. Clear biomes you know and save your flask for the boss.
