Meet zombie

A zombieman firing upon the player in E1M1: Hangar (Doom)

 
"Just a few days ago, you were probably swapping war stories with one of these guys. Now it's time to swap some lead upside their head."
― Description in the Doom Manual.
 

The zombieman (also known as former human or, sometimes, former soldier in the game manuals) is a space marine which has been turned into a zombie during the invasion from hell. It appears as a man in a bloodstained tan uniform and body armor, carrying a semi-automatic assault rifle that uses pistol bullets. The zombieman is the least powerful monster in the Doom bestiary.

Combat characteristics Edit

The zombieman will make one of three different sounds when alerted: it will either make a short bark, a ferocious roar, or a low cat-like growl. All three zombie types make the same sounds when they spot the player or die. The zombieman is armed with an assault rifle that fires bullets that are slightly less damaging than the player's bullets. When the zombie attacks, it aims its rifle at the player for 10 tics and fires a single pellet. The zombieman's weapon has a wide dispersal (standard deviation around 9°, to a maximum of ±22°), and will most likely miss at medium to long ranges. After firing, the monster moves again.

The zombieman is generally considered the least dangerous enemy in the game; no other monster (excepting the Commander Keen) has a lower movement rate, hit point total, or average damage per attack. Due to their bullet weapons, they can be easily made to engage in monster infighting with others of the same type. When killed, the zombieman falls hard on its back and will emit one of the two kinds of moaning or a low pitched scream as various bits of blood and flesh are blown off from its midsection, its lower jaw partially torn away, and dropping an ammo clip containing 5 bullets (or 10 on I'm too young to die and Nightmare!). If he subsequently respawns or is resurrected, the zombie will drop another clip when he is killed again. He can also be gibbed if attacked with powerful weaponry, such as a rocket launcher.

Tactical analysis Edit

Unless in poor health, an armed player should never need to back down from a single zombieman, although large groups can slowly drain the player's health during the time it takes to kill them all (as in Evilution MAP09). The dispersal of the shots from its rifle means that it is barely a threat at medium to long ranges. In an emergency, or when conserving bullets during a Tyson run, the fist is effective in the short term if the player's footwork is good (two blows will usually knock one down, while a single berserk attack will certainly finish it, often gibbing it). As they are extremely weak and easily disposed of, using heavier weapons against them is considered a waste.

The zombieman's low rate of fire and damage capability make it a rather weak contributor to monster-monster battles. Attrition among a crowd of zombiemen is generally slow, and distraction of larger monsters minimal.

In most stock levels, many of the enemies in the first few rooms are zombies. Unless the player's primary goal is speed, the zombiemen's dropped clips can be a valuable early source of ammunition.

NotesEdit

  • The zombieman has the type name MT_POSSESSED in the Doom source code, and the sprite prefix POSS, while the analogous MT_TROOP and TROO are given to the Imp. The zombies were called "demon-possessed humans" (or simply "possessed humans") in the Doom Bible (section 7.2), being "possessed in their sleep".
  • With only 20 hit points, the zombieman can be gibbed with the berserk fist, rockets, the plasma rifle, the BFG9000, exploding barrels, Demon bites, Cacodemon ranged and melee attacks, Hell Knight/Baron of Hell clawing and ranged attacks, Revenant rockets, Arch-Vile fire attacks, and--on rare occasions--Imp fireballs or melee attacks and even other Zombiemen. This means this monster has more ways of being gibbed than any other monster.
  • In a ZDoom-based source port, if the player is killed by a Zombieman (monster is credited with delivering the blow that reduces player's health to 0%), an obituary message is displayed at the top of the screen: "[player name] was killed by a Zombieman".

  1. This table assumes that all calls to P_Random for damage, pain chance, blood splats, and bullet dispersal are consecutive. In real play, this is never the case: counterattacks and AI pathfinding must be handled, and of course the map may contain additional moving monsters and other randomized phenomena (such as flickering lights). Any resulting errors are probably toward the single-shot average, as they introduce noise into the correlation between the indices of "consecutive" calls.
  2. The target must be close enough to compensate for the monster's inaccurate aim.
  3. Assumes that direct hits are possible, which does not occur in any stock map.

Other games Edit

Doom 3 Edit

See Z-Sec.

PlayStation DoomEdit

In PlayStation Doom, their gunshot damage is increased somewhat, up to a maximum damage of roughly 21. The manual also lists the name of this enemy type as "Former Soldier", as opposed to "Former Human" as in the PC versions' manuals (or "Zombieman" as in the enemy cast at the end of the game).

Doom 64Edit

Doom64Zombieman1-D64ex

A group of zombiemen in Doom 64 MAP01: Staging Area.

In Doom 64, they use a visual appearance that is similar to the Vanilla Doom looks, but instead their rifles look more like shotguns and their suits are colored blue-grey. They first appear in MAP01: Staging Area. Also, like in PlayStation Doom, their gunshots deal somewhat more damage than in previous versions (up to about 21 damage).

Doom RPG Edit

In Doom RPG, the zombieman appears as the "zombie" monster class. There are three different forms, identified by color:

  • Zombie private (brown)
  • Zombie lieutenant (blue)
  • Zombie captain (normal colors)

They are weak against axe attacks.

Trivia Edit

  • In Doom II for the Game Boy Advance, a red blood splatter, half-way covered in green, appears in the zombieman's death animation.
