However, the groaning that standard Zombies constantly make in Half-Life 2 are heard as a victims' muffled attempts to yell for help. It is not currently known if a person is technically alive after turning into a Zombie. This is notable for the Rebel outposts along the City 17 Canals (in and beyond the Underground Railroad) or in cases like Ravenholm. Headcrab Shells will often be sent to Resistance camps to dismantle them, turning the Rebels stationed there into Zombies with the use of Headcrabs. Zombification is also one of the ways used by the Combine to subject and intimidate the human race. Also in Half-Life 2, certain Zombies can be found "sleeping" and stand up to attack the player if they get too close or are attacked, as if they were playing dead.Īs Headcrabs do not attach themselves to native Xen creatures, Zombies are only found on Earth, usually in remote or deserted areas. Zombies mainly attack with swipes from their claws, but in Half-Life 2, they gain the ability to forcefully punt objects towards the player. Zombies do not respond to fire, and will walk blindly into it, though they do feel it on them and notice they are burning once they are on fire.
