Why Headcrabs Are So Terrifying - Half-Life: Explained

In this video I explain the headcrabs and zombies from the half life series. We cover the wide range of different zombies you can encounter throughout the series. I used the Headcrab+ mod for Garry&Mod to gather the footage of what headcrabs would act like in reality. In-game, they do not infect anybody unless it is scripted. I&also aware that I didn&cover the lightning dog/headcrab, this technically isn&a headcrab and will be getting its own video. ==In This Video== Music: "Darren Curtis - It&In The Fog" is under a Creative Commons license (CC BY 3.0).
