idk if this is where i put this but i found that sometimes, seemingly at random, the beetles will fight one another. this includes the bombardier beetles and the devils coach horse beetle larvae and adults. idk if this is intended or is a glitch.
I say when you release the game start working on making some of these suggestions togglable in freeplay so those who want a more simulation like feel can have that while the main campaign stays its natural RTS like self but that's just a suggestion of mine.
