Cannon: The beetles' horns are cannons that can fire Dark Matter shells on targets, apparently exploding on impact. It does not use gunpowder; it does not smoke when fired. Instead, it uses a spring system to fire the shells. The shells detonate by breaking the hardened outer coating with sponge springs, as such, their acoustic effect is only 36% to 50% than that of a normal shell, making it infeasible to weaponize the shockwaves generated by the shell on impact. Moreover, the shells are unable to destroy other beetles. The cannon is as strong as those of warships.
