this is exactly what this mod does
the Biters/Spitters can take over your base, like The Engineers in Command an Conquer
Instead of destroying buildings and facilities, the building changes faction.
This can't really be explained in pictures but maybe in a short video clip.
Place a radar near a nest and watch the biter/spitter attack the building and take it over when the HP reaches 0. After that the building is back to 100% HP. Depending on the type of building, this could be unpleasant for the player.
Laser Turrets Shoot at you as long as they are still connected to their own player energy grid.
Turrets Shoot at you and other turrets as long as they have ammunition supply through conveyor belts.
Flamethrowers do the same
👍
But you can no longer recapture the buildings.
