Biome Menu
Read each biome like a map screen, not a backdrop.
Quick Facts
Fast read before the full guide
Officially Confirmed
Four biomes are part of the run structure.
What This Menu Tracks
Pressure, route cost, local threats, and build comfort.
Main Decision
Knowing when the environment wants you to hunt, flee, or pivot.
Best Companion
Pair biome pages with builds and boss prep, not only with lore reading.
Biome Routes
Pick the biome question you actually need answered
Environment Pressure
Start by asking what the space is punishing, not what it is called.
Use this first when you want a framework for route exposure, visibility, tempo loss, and local threat density.
Systems View
Look at biomes through the parts of a run they most likely reshape.
This page organizes biome impact around route safety, resource efficiency, build comfort, and threat density.
Practical Reading
Notice biome pressure before it turns a stable run into an expensive mess.
Use this when the environment feels like the hidden problem behind repeated run instability.
Why This Menu Matters
Strong builds still fail when the map rejects them
A strong build in one environment may become awkward in the next.
Weather and local conditions can change the value of mobility, sustain, and burst.
Some routes are cheap only for certain body plans or evolution packages.
Boss preparation is biome-sensitive in practice, not only damage-sensitive.
