Heavy weapon dude


 * For the chaingun wielding zombie in Doom 3, see Commando (Doom 3).

The heavy weapon dude (called a former commando in the Doom II manual) is the most powerful type of human which has been turned into a zombie during the invasion from hell. The monster appears as a robust red-eyed bald man with a bloody mouth, wearing bloodstained, red body armor and boots over slate-gray pants, and carries a chaingun with its accompanying ammo belt. Its skin tone is a bit darker than that of the other former humans, and it is the first of the enemies introduced in Doom II to make an appearance in the game.

The Doom instruction manual says: ''Geeze, weren't shotgun zombies bad enough? At least when you fade these jerks you get a cool chaingun.''

Combat characteristics
The heavy weapon dude attacks by firing its chaingun, which does slightly less damage per bullet than the player's chaingun and has a rate of fire that is also a bit lower. Once the chaingun guy begins to fire, it continues until its target dies or leaves its line of sight, or the monster is stunned (causing it to move immediately afterward) or destroyed. When felled, it falls apart and it drops the chaingun, which contains 10 bullets (or 20 on the "I'm too young to die" and "Nightmare!" skill levels).

Tactical analysis
Because heavy weapon dudes employ a ranged attack that starts quickly and continues in rapid succession (even the spiderdemon pauses briefly in its tracks before firing, giving the player a fraction of a second to take cover), which cannot be dodged, the player must avoid spending any time within short or medium range of them, if possible. One shot from the shotgun at close range often kills a chaingun dude, and continuous fire from the player's chaingun at close range almost always prevents the zombie from firing, while chaingun "tapping" normally limits it to retaliating with a couple of shots during the remainder of its existence. If there are multiple chaingunners in a clustered formation, usage of the rocket launcher or plasma gun is recommended. Since, like all monsters, heavy weapon dudes do not have any limits on ammunition used, multiple chaingun zombies at any good distance can quickly drain the player's health in the time it takes to cross a large room; in such a situation, it may be essential to remain in motion.

The heavy weapon dude's high rate of fire makes it a formidable presence in monster-monster battles; provided it survives the initial blow (Given their 70 hit points, this is usually the case with an unharmed one), one of these zombies can often take down a healthy cacodemon or revenant. A heavy weapon dude can also sometimes defeat a hell knight, a mancubus or an arachnotron at close range, when the chaingun manages to continuously stun the opponent, preventing any return fire. Like all hitscan-firing enemies, heavy weapon dudes will gladly turn on each other if provoked.

Because of their unrelenting automatic fire, and their tendency to appear in large numbers, they are not enemies to be taken as lightly as other former humans are. They should be considered a high priority threat in cases where there are many in an enclosed area, even when there are more powerful enemies in the area. Close range encounters with heavy weapon dudes can quickly get you killed if they are not disposed of quickly.

Final Doom is noted for having a high number of these foes, especially on the ultra-violence difficulty.

Data



 * 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.

Appearance statistics
In classic Doom, the heavy weapon dude is first encountered on these maps:

The IWADs contain the following numbers of heavy weapon dudes:

Doom RPG
In Doom RPG, the chaingun zombie appears as the "commando" monster class. There are three variations, identified by color:


 * Troop (yellow)
 * Commando (blue)
 * Assassin (normal colors)

Their attacks are capable of destroying jammed doors, much like the axe does, and will attack three times consecutively. They are weakest against plasma attacks.
