A comprehensive upgrade to Biters, making them a considerable challenge at all stages of the game. Bigger biters will split into smaller biters, nests will spawn biters when they die, and as evolution increases, so will the number of enemies you will have to face! Compatible with all (hopefully) mods that add new enemies.
Load/Enable this mod to disable the spawning of enemy bases on newly generated chunks. Unloading/Disabling this mod restores the generation. This way you can go mega without having to use lua commands (=losing achievements) or restart the game, but prevent new spawners from being created. Existing enemies may still expand on their own!
Add support to have multiple races of enemies and add leveling to enemy. Enemy becomes tougher as they level based on your pollution and killing factors. This mod only enhance vanilla biters. Please visit the mod page to download the new demo race or search "ERM -" mods.
