This mod removes biters' and pentapods' spawners from the maps and adds alternative recipes to make Pentapod eggs and Captive biter spawners.

Main feature

• Removes biters' and pentapods' spawners from the game.
• Adds an inefficient recipe to produce Pentapod egg instead of looting from the spawner.
• Adds a primitive recipe to produce Captive biter spawner, unlocked by Agriculture science packs (Cryogenetic science packs are NOT required).
• Biter spawner will NOT remain when built Captive biter spawner is spoiled.

Note: the recipes in vanilla to produce Pentapod eggs and Captive biter spawners will NOT be removed.

Optional feature

• Removes Captive biter spawner from the game and adds an alternative recipe to produce Biter eggs. Note that this feature is NOT compatible with mods using Captive biter spawner as an ingredient of any other items.

For existing save files

This mod can be applied to the existing save files. In this case, the spawners generated before this mod was applied will be deleted whenever possible (maybe imperfectly all).

About demolishers, and enemies generated by spoiling

This mod does not remove demolishers or enemies generated by spoiling in the default because it will be removed by "New Game > Map generator > Enemy > No enemies." If you want to remove them by this mod, you can enable "Forcibly no enemies" in mod settings. However, it cannot be cancelled and should be enabled for only saved games without "No enemies" by vanilla.
