Configurable evolution thresholds for Armoured, Cold and Explosive biters (when present). Spawner evolution is adjusted in data stage; a lightweight runtime filter prevents small special biters from appearing before the configured evolution threshold.
Small changes concerning balance, gameplay, or graphics.
The mod was made for a personal game, therefore this mod is not "production ready". The intent is to gate the new modded types of biters by evolution factor.
I may end up refining it at one point, but atm it is a bunch of AI slop stitched together "just so it sort of works".
