The '''Poison Zombie''' is the resulting Zombie of a human host under the control of a Poison Headcrab. The mutations that take place produce a bloated, slow-moving zombie that is capable of carrying additional Poison Headcrabs.

==Overview==
FileD2 coast 070026.JPG|200px|thumb|left|Poison Zombie at Bridge Point.

Poison Zombies are bloated, reddish purple, slow-moving Zombies. They are almost always seen carrying an additional three Poison Headcrabs on their back. It appears that the Poison Zombie's model is an old man's, but its stooped posture and shuffling gait could also be caused by the weight of the attached headcrabs, or (as seen by the exposed spinal column) because it's missing all the supportive muscles from its back which would allow it to pull the upper torso into an upright standing position.

The Poison Headcrabs riding on the zombie's back can leap off when needed to attack on their own, but cannot reattach themselves to the poison zombie once left.

Another trait that distinguishes the Poison Zombie from other zombie types is its endurance. Poison Zombies can take three times as much damage as other zombies before collapsing. 

Poison Zombies themselves are not poisonous, and rely on the hitch-hiking Poison Headcrabs to attack first. Then, it resorts to its claws. Poison Zombies can be detected by their loud, strangulated breathing and muffled groans. They also emit loud, whale-like howls.

Poison zombies are unique in the fact that the headcrabs attached to their bodies appear to be interacting with their host. While other Headcrab Zombies serve as a host for individual headcrabs, the poison headcrabs attached to a poison zombie appear to be from it. The fact the poison zombie is off color and bloated would suggest that the headcrabs are either sucking nutrients from the body (which would explain why the headcrabs on a Poison Zombie's body seem to pulse), are causing enough damage to make the host lose almost all of his blood, or are using the body to store or create their acute neurotoxin. It has also been speculated that poison headcrabs may lay their eggs in their hosts' bodies, which would explain the hosts' bloated appearance and the multiple poison headcrabs which cover them. It should be noted that unlike other types of zombies, Poison Zombies cannot be cut in half.

Poison Zombies are first encountered in ''Half-Life 2'' Chapter 6 ''"We Don't Go To Ravenholm..."''.


==Tactics==

Poison Zombies can take a lot more damage than other zombies (roughly 300%), and have better attack capabilities. 

* The most effective weapon against Poison Zombies is fire; when hit, the zombie will set alight the headcrabs as well. A very good tactic is to grab a propane tank or gas canister, pop out of cover, light up the zombie then take cover before it throws more headcrabs. It will die and take its passengers with it without causing any damage. The fire will take a while to kill them so try to stay away if you can. If no flammable objects are present, take advantage of headcrabs and their host's flammable nature by chucking MK3A2 Grenade|hand grenades or firing MP7 grenades. If you are running low on these, try to find explosive barrels, though the explosion cannot light the Poison Zombie up, it can inflict good damage on it.

* At close range, moving around while attacking to avoid being hit by the thrown headcrab. Normally there are three riding headcrabs, when a thrown Poison Headcrab comes into contact, health points will drop to 1, but will gradually increase by increments of 10 as the HEV Suit administers an antidote to the venom. Therefore, it is advised not to use the Crowbar against incoming thrown headcrabs, Gravity gun can sometimes push back the incoming Poison headcrab, but this is not 100% safe and not recommended if you have space to maneuver. 

* When the player has Energy Ball|energy core to spare, is recommended to equip the OSIPR|Pulse Rifle and use its alternative fire on the Zombie. This will disintegrate the zombie along with its passengers, all headcrabs will detach; however, they instantly touch the fusion orb as well, which means immediate death.

* Using the Resistance Crossbow|crossbow against it. Get away from the poison zombie, and aim at its headcrab passengers, this way the poison zombie should die without the release of poison headcrabs.

* Waiting until all of its headcrabs are thrown off and killed. The zombie should be a minimal threat without the hitch-hiking poison headcrabs on its back.

==Trivia==

*There is no difference between the Poison Zombie and the ''Half-Life 2'' Beta "Fat zombie" Aside from the spine on its back and the skin, this is easily notable by the feet.
*The Poison Zombie appears to be several times stronger than its brethren, on multiple occasions, Poison Zombies can destroy entire doors. In ''Half-Life 2 Episode One'', in the hospital level, several Standard Zombie|regular zombie are seen trying to claw open a doorway, but it is not until the Poison Zombie arrives when, with tremendous, seemingly explosive force, the door is destroyed.
*When the Poison Zombie dies, there are two sounds for his death. The end of one of the files sounds like the laugh (or possibly a cry) of an old man, indicating that the zombie NPC seen in-game could have been an older man when he was human.
*Oddly, some of their sounds seem to be reversed donkey and bovine sounds.
*When a Poison Zombie makes it into the path of a Barnacle, the game will crash. This can be seen without the use of cheats/mods towards the end of Anticitizen One in the tunnels after Alyx is captured. The player should lure the Poison Zombie towards the nearest Barnacle using the chain-link fence as a ramp. No attempts have been made to fix this.
*The Poison Zombie's second breathing sound (pz_breathe_loop2.wav), sounds like a deeper variant of ''http//left4dead.wikia.com/wiki/Left_4_Dead_2 Left 4 Dead 2's'' http//left4dead.wikia.com/wiki/The_Jockey Jockey.
*If the player uses the cheat "notarget", it can be seen that the headcrab on the head of the Zombie is bouncing.
