Info
A headcrab is an alien parasite that latches onto human's heads, turning them into zombies. Their small size allows them to scurry around in vents or 'burrow' into sand. They can be difficult to hit due to their size, and once they're close enough they will jump towards the player, but they are otherwise fairly slow and weak. Bullsquids have a particular hatred against these creatures.
