The secret level enemy! These guys are returning from Wolfenstein 3D, although they are quite different from that game. They fire in continous fashion, similar to a zombie commando, albeit not as dangerous. They will appear in small to large groups in the secret levels and don't appear anywhere else but custom levels.

Countermeasures: Anything really, but the Chaingun is ideal because they drop ammo for it.

Trivia: Due to Dooms' larger sprite size (compared to Wolf3D), this enemy appears rather short by comparison.

Danger Level: 1-2

Slightly more annoying than a Zombieman, but only moderately more dangerous.

HP: 70
Damage: 3-15 (Bullet)
Pain Chance: 66.41%

The Chaingunner is a new zombie type in Doom II. He is a lot more dangerous than the previous undead and although his chaingun doesn't fire quite as fast as yours, it can still kill you pronto if you don't get behind cover or kill im fast. He never stops firing unless hes getting hit or loses track of his target. He can mow down other smaller and even some medium monsters easily if you make him do so.

Countermeasures: Chaingun or Shotgun. Plasma Gun for larger groups.

Trivia: This enemy closely resembles a number of boss characters from Wolfenstein 3D. Its style of armor and usage of a chaingun is highly reminiscent.

Danger Level: 3-5

Super dangerous. The only balancing factor is that vanilla Doom II doesn't overuse these things. Custom maps are a different story though *cough* Plutonia *cough*. If encountered in a group or ambush, you will end up with more holes than swiss cheese.

HP: 500
Damage: 10-80 (Claw), 8-64 (Energy Blast)
Pain Chance: 19.53%

The Hell Knight looks just like a Baron of Hell at first glance. Their attacks, speed and size are the same. The Hell Knight however has 50% less HP, making a bit easier to kill. The damage he does with his attacks is still just as high though, so treat him the same as the Baron: dodge at all costs.
Fighting other monsters is a breeze for this guy most of the time.

Countermeasures: Rocket Launcher and Super Shotgun.

Trivia: ID made the Hell Knight because they felt that the Baron was too strong as an ordinary enemy so they made this guy the common mid-range monster in Doom II, whereas the Baron of Hell became a rather rare threat.

Danger Level: 3

Easier to kill than a Baron, so you can remove them more quickly, but they hit just as hard. Just like with its red counterpart, do not let these guys box you in.

HP: 300
Damage: 8-64 (Punch), 10-80 (Fireball)
Pain Chance: 39.06%

The Revenant is a pain in the a**. This guy moves very quick and up close punches you to death with his fists. Should you engage him at range, he will fire fireballs. The problem is that you cannot really predict what kind of fireball its gonna be. He either fires ordinary or homing ones. The homing balls can be hard to avoid, especially in narrow corridors. Try to sprint, strafe or get behind a wall to get rid of it, as the ball will never run out of juice. One can even lock these into stable "orbits" around you. Although he is easy to kill, his speed and the insane damage of his attacks makes him one my least favorite monsters to run into. Ironically he tends to lose against most mid-range monsters when infighting.

Countermeasures: Super Shotgun, Chaingun and Plasma Gun. BFG 9000 for larger groups.

Danger Level: 3-4

Much like with the Chaingunner, they aren't a huge problem in vanilla Doom II. Custom maps love spamming these bastards, however, so be prepared to dodge a million rockets. Plasma gun is the safest and fastest way to kill individual Revenants, but the BFG is your only real option against a large group.

HP: 600
Damage: 8-64 (per fireball), 48-384 (total volley)
Pain Chance: 31.25%

The Mancubus is a tank. He moves slowly, is tough and hits hard. His spreadfire fireballs can be very hard to dodge and require observation and experience to avoid. Should he get all shots in, you are pretty much guaranteed to be dead. In close quarters, this thing can be the end of you. He is excellent for monster infighting, as his massive size makes him easy to hit and his attacks tend to hit multiple enemies if they are clustered together. In such a case he quickly kills everything but the bigger monsters in no time.

Countermeasures: Super Shotgun, Rocket Launcher, Plasma Gun and BFG 9000.

Danger Level: 3-4

These guys spam fireballs, so, just like with the Cyberdemon, you have to learn their pattern. It isn't as easily memorized though. Close quarters are the worst place to encounter these.

HP: 500
Damage: 5-40 (Plasma Ball)
Pain Chance: 50%

Looks familiar doesn't it? Although the new spiders are smaller than their mastermind counterpart, they can be just as deadly. Arachnotrons can be seen as siege engines. They start firing plasma and never ever stop unless you die or they get hit. They can be easily tricked into shooting other monsters and can literally be lured into shooting down rows and rows of them. Strafe and/or run to avoid the plasma.

Countermeasures: Chaingun, Rocket Launcher and Plasma Gun.

Danger Level: 3-4

The DPS monster. So many plasma balls they can make the level look like Christmas. Thankfully, their behavior is extremely predictable. As long as you can strafe, you are safe. But get hung on something and you are fried.

HP: 400
Damage: 0 (spawn)
Pain Chance: 50%

I'm gonna be honest: I don't like this thing. It may look like a Cacodemon, but other than the fact that they both float and have similar HP they got nothing in common. Pain Elementals don't even do any damage on their own. So whats so bad about them? They spit Lost Souls instead of fireballs! If you don't kill this thing quick, you are gonna drown in flying skulls. Just kill this monster on sight with maximum prejudice. The Lost Souls think independently from their creators, so there is no way any monster will ever attack a Pain Elemental intentionally.


Countermeasures: Super Shotgun, Chaingun, Plasma Gun and BFG 9000 (for groups).
WARNING: Do not use rockets. If you do, chances you are gonna hit the Lost Souls charging you after getting "launched", resulting in frying yourself.

Danger Level: 3-4

Kill. Death. Murder. That should be the only thing on your mind when you see these. Let them live and the map overflows with Lost Souls. They can't defend themselves as they have no melee attack (odd considering those massive teeth).

HP: 700
Damage: 20 (direct hit), 0-70 (blast radius)
Pain Chance : 3.91%

This is by far the most dangerous non-boss monster in Doom ever and at the same time my absolutely hated nemesis. Although he has less HP than a Baron of Hell, the fact that he is faster than almost any other monster makes them hard to hit, especially with rockets. The Archvile employs 2 moves. The first is an incinerating attack that seems to have no range limit, putting you on fire and then blowing you up. Break line of sight immediately once you can tell you are on fire, otherwise you get roasted. Trying to interrupt its attack is a HUGE gamble, because this thing has a near non-existant pain chance. If the Archvile catches you at point-blank range, one last ditch effort you can do is to use the Super Shotgun, as it has the highest chance of interrupting his attack. His second technique is a resurrection ability that allows him quickly reanimate the corpses of other monsters. Cyberdemons, Spider Masterminds, other Archviles, Lost Souls and Pain Elementals are exempt from that. Kill this guy ASAP.

Countermeasures: Super Shotgun (point-blank), Plasma Gun, BFG 9000. (Rocket Launcher works too, but he moves very quick so you gotta be great at aiming.)

Trivia: Its death sound resembles a garbled "WHY?!". The reason for this is, that this monster genuinely doesn't think its doing any harm by help resurrecting its fellow demons. It also has the lowest pain chance of any Doom monster.
Its attack launches players into the air. A common technique among seasoned players is to utilize Archvile attacks to reach platforms that are out of reach. This can also commonly be observed in speedruns.

Danger Level: 5 (varies depending on the environment and how many corpses are around)

No monster in Doom should be prioritized as highly as this one at almost any given moment. Kill them immediately and use cover to avoid their telegraphed attack. With a long range attack, insane movement speed, HP and the ability to resurrect 90% of the other monsters, this is THE most dangerous monster of Classic Doom.

HP: 250 (Head)
Damage: Instant Kill (Teleport Kill)
Pain Chance: 100%

This guy's head is stuck in a wall and he's the last obstacle of the game. He continously fires monster cubes that will erupt into flames and spawn a random non-boss monster. He never stops doing so, so you are on a clock to kill him before you get overwhelmed. Shooting him directly has no effect. The trick is to elevate a platform and fire rockets into its exposed brain. 3 rockets will shut him up. He can kill you directly though, if you stand exactly on the spot where a monster is supposed to spawn, thus telefragging you.

Countermeasures: Rocket Launcher.

Trivia: Along with the Lost Soul, this is the only monster in Doom 2 that has a 100% pain chance. Also, when firing rockets into him, this is what you are actually hitting:


Its the head of John Romero, co-founder of ID Software!
The sound you hear when facing the creature reads this when reversed:
"To win the game, you must kill me, John Romero!"

Danger Level: 5

Not much to say here. You can't leave the level unless this thing dies and if you let it live you drown in endless monsters. It is extremely dangerous but only appears maybe once per map pack.
