Zombieman
From Doom Wiki
The zombieman (also known as former human in the game manuals) is the least powerful type of human which has been turned into a zombie during the invasion from hell. The monster appears as an man in a bloodied tan utility uniform and body armor, carrying an assault rifle. Its hair has a greenish tinge, perhaps stained with green slime.
The Doom instruction manual says: 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.

[edit] Combat characteristics
The zombieman is armed with a rifle that fires bullets, although they are slightly less damaging than the player's bullets. When the zombie attacks, it aims its rifle at the player for about 3/10 of a second and fires a single pellet. The zombieman's weapon has a wide dispersal (standard deviation around 9°, to a maximum of ±22°), and may 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. When killed, the zombieman drops 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 clip remains.
[edit] Tactical analysis
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).
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.
[edit] Inspiration and development
An early version of the zombieman appears in the IWAD file of Doom 0.4, although the sprite (POSSA) does not appear in the game. The sprite is almost identical to the Doomguy; it is slightly lighter in color, and has crudely drawn square red eyes (to show that it is possessed). The only frame is a full frontal view, with no rotations. In Doom 0.5, however, the sprite is virtually identical to the finished version.
[edit] Notes
- 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".

- 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.
- The target must be close enough to compensate for the monster's inaccurate aim.
- Assumes that direct hits are possible, which does not occur in any stock map.
[edit] Appearance statistics
In classic Doom, the zombieman is first encountered on these maps:
The IWADs contain the following numbers of zombiemen:
| Game | ITYTD and HNTR | HMP | UV and NM |
|---|---|---|---|
| Ultimate Doom | 203 | 338 | 384 |
| Doom II | 221 | 268 | 290 |
| TNT: Evilution | 337 | 370 | 443 |
| Plutonia | 117 | 81 | 86 |

[edit] Doom 3
- See Z-Sec.
[edit] Doom 64
In Doom 64, they use a visual appearance that is similar to the Vanilla Doom looks, but instead their rifles look more like shotguns.
[edit] Doom RPG
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.
