Enemies fight with each other

[ParaSait]

Like in the original DooM,if an enemy accidently bites/shoots/claws another enemy,they will start fighting with each other!Could be an interesting feature for DoomRL too.

Monster Infighting. This've been suggested before - by me - but dunno what's the status right now. How's it going with this Kornel?

It occurs to me that if the Spider Mastermind ever went in, the Gotcha! scenario might be good for testing whether mechanics/balance/whatever are correct.

In original Doom, infighting has some limitations, which are not true in DoomRL
1. Realtime, which deals infighting harder to use - you must watch to monsters, do they fight you or others.
2. Exceptional strength of cyberdemon. Even if cyberdemon wounded by infighting, and player has 200% hits and armor, and full ammo, cyberdemon is a big threat.
3. Not-random levels, which means you can use infighting only if level-maker allows it.
4. Monsters of one type, except all types of former humans and souls, do not fight each other. For example, you can't see fighting of two cacodemons.

And all that can't be realized in DoomRL, or hard to realize. Without that, the game will be much more disbalanced, than it disbalanced now.

To do some nitpicking: This one is actually possible if one of the cacodemons blew up a barrel with another one next to it. But they still couldn't do any damage to each other.

Monsters could not be hurt by the same type of monster weapon as they use with an exception of bullets.

In DRL it would be much easier to provoke in-fights than the original.
And it would be way too easy to abuse unless AI is changed accordingly.
