Biomes

Biomes are the different areas within Dead Cells which players must progress through. There are currently seventeen biomes, with plans to add more.

Within each run, biomes are procedurally generated within the confines of that biome's set parameters. This puts the focus of gameplay on adaptation rather than memorization, while maintaining each biome's distinct feel. The order in which you'll encounter biomes, and the general location of their exits, are predetermined.

With the exclusion of the Black Bridge, the Insufferable Crypt, the Clock Room, and the Throne Room, each biome always contains a shop and at least one treasure chest.

After exiting each biome, the player will enter the Collector's room. Here, they can turn in blueprints, spend cells, enter Timed and Perfect Doors if they met the requirements and replenish their health and health potions. Time spent near treasure chests and within shops and the Collector's room does not count towards Timed Doors.

Note: scaling of enemy and trap stats with tiers operates somewhat differently compared to scaling of player damage and health with Stats - though damage and health initially scale exponentially using bases of 1.09 and 1.08, respectively, there are also additional factors in the code called "scale multipliers per tier" with values of 0.55 and 0.12 for damage and health, respectively. It is not yet known how these modify the exponential formulas to produce final enemy and trap stats.

You will also find in many Biomes a set of doors with up to four circles on them, in random spread-out locations. These can only be unlocked once you have obtained the necessary number of Boss Stem Cell s that are only obtained by doing a complete run, and unlock further challenges.

See Biomes_Table for condensed view.

Only enemies present in the stage appear to be Cannibals, which are lot stronger than usual. The majority of the stage is locked behind the door that requires the 'Key' key to open.
