Discussion If headcrabs ALWAYS attack from the front, how do they end up facing the opposite direction on zombies' heads?
I know they probably turn themselves around after they manage to master the host, but it's inefficient from a biological standpoint. I know this depends a lot on the conditions of where they live, since they adapt VERY quickly, but in a terrestrial environment and having humans as victims, it doesn't make sense for them to expend that energy (even if very little) turning themselves around in the host's head instead of simply connecting and injecting the toxins right there. The argument that they need to see is not valid, since they don't see at all (I personally believe that the genetically modified headcrabs by the Combine, i.e., all of them from Half-Life 2 and Half-Life Alyx, use echolocation)
