Imagine if alpha commanders had 6000 HP each.
You can't blow their heads off to kill them, they just rage and keep attacking you repeatedly until you burn through their hp bar. Cutting off their legs didn't stun or slow them. Cutting off both their tiny arms though prevent them attacking you, but their arms are 800 HP each.
Then imagine they can't be staggered, and they cannot be reliably stunned.
You litterally just shoot them.


That's flesh mobs
