My opinion on headcrabs applies to many enemies in games. I hate floor level enemies I can't just jump on. Especially if they get up close enough it becomes awkward to tilt or bend down or whatever trick is needed to actually hit them.
funny thing about Angies method is that it protected the entire body EXCEPT the head. Meanwhile, Morgan goes for the simplest yet most effective way. Talk about over engineering.
funny thing about morgan's method. there's a game called phantasy star online 2, and in it, there's a playable race that has horns. there's also an emote that has a headcrab jump at your face and latch on. combine the two and, well, nothing actually happens, but it should.
