DOOM II: Hell on Earth – Monster Infighting Guide

How to trigger monster Inifighting

 
So how and why do demons decide they hate each other, well it’s because one demon axxednetily hit another demon, then this demon retaliates, and when the inflicter gets hit, then they fight back, and a raging internal battle is triggered 
 
Lets look at an example 
 
This Hell Knight is trying to hit that Doomguy (me), but is dumb and hits the Revenant instead 
 
 
 
The Revnant is dipleased with this and socks the Hell Knight right in the jaw 
 
 
 
And now Doomguy doesn’t have to kill the demons himself! 
 
The Hell Knight won btw 
 
 

There more to it however

 
Somtimes there’s a Cyberdemon chaseing you down, and a lot of other Baddies trying to hit you, but they all hit the Cyberdemon instead, but it won’t retaliate, why won’t he fight back, why does he hate u so much? 
 
 
 
It’s to do with the targeting threshold 
every demon has their own targeting threshold, except for the Archvile, but we’ll get to him 
Basically a Demon won’t switch targets unless it’s threshold is 0, but what Ticks the Threshold down? 
For every Step a Demon Takes it’s threshold will Tick down, if its threshold is 0 but it has no interest in switching targets, then its threshold will reset to 100 
 
 

Why won’t they get hurt by each other?

 
Have you ever tried to get 2 Imps to infight, or a Baron of Hell to infight a Hell Knight, only to soon find out they can’t hurt each other, whats up with that, are they immune to their own projectials? 
 
 
 
No 
 
Contrary to popular belief, it isn’t the Projectial that determines whether a Demon can hurt another demon, the game compares the Thing that threw the projectial and compares it to who got hit by it if they are the same demon then don’t deal damage, but if that’s the case why can’t Hell Knights and Barons hit each other, well there are some exceptions to this rule 
 
First Barons and Knights, as seen in the image 
 
Second lost souls, their attack can deal damage to anyone, even other lost souls 
 
 
 
Third Non coop players, imagine playing Death match and not being able to kill someone with a rocket 
 
 
 
 

Oddities

 
There are some anomiles present 
Like the Archvile 
 
Remember Targeting Thresholds? Well the Archvile doesn’t 
 
 
 
As soon as something or someone hits Sir Arch he will immediately retaliate without any hesitation 
 
Remember how things retaliate when hit by something else? Well no demon in the ENTIRE GAME EVER Fights back at the ARCHVILE, not ONE DEMON, not Cyberdemons, or Barons Of Hell, or lost souls, NOTHING, except the Player, or “friendlies” but those don’t exist in normal Doom so we won’t discuss those. 
 
 
 
Also lost souls are a whole other can of worms 
 
They can infight fine, but only for one attack, then they forget who they were mad at and start hunting down the player instead UNLESS the player didn’t make a noise if the player didn’t make any noise (Shooting basically) then they will fall asleep until they get hit, see the player or the player makes a noise 
 
 
 
 

Credit Where Credit is due

 
Thanks Decino! 
 

 
Also I should’ve Credited the makers of LZDoom, but I don’t know who those are so here’s the download site instead 
 
https://zdoom.org/downloads 
 
I found who made GZDoom 
 
Christoph Oelckers 
GZDoom is a ZDoom-based port which is maintained by Christoph Oelckers (Graf Zahl). It was first released on the 30th August 2005 and runs in Linux and Windows. Its development was halted on April 14, 2010, except for updates to keep its codebase in sync with ZDoom.
