When an enemy unit or worm dies it tries to reincarnate back in to nature, be it a tree, rock, cliff or water. Occasionally the angry biters can burst into a flaming tree.
Mods introducing new content into the game.
Changes to enemies or entirely new enemies to deal with.
i like this mod, but i hate cliffs, please add an option to disable cliff generation.
You can change the mod settings for the generation chance. Set cliffs to 0 and biters won't reincarnate as them.
