Based on the idea of Hideous Destructor and other difficult mods...
v1.2
https://www.dropbox.com/s/kv2wlysz2m400 ... 2.pk3?dl=0
Have you ever wondered what enemies would be like if they were smarter? How would it feel to be the doom marine going through a very realistic scenario instead of the bullet shield enemies in doom?
What this mod seeks to accomplish is just that. Jam packed with AI, more variety, more items, add a Doom 3 feel, and make it tough. Adds more atmosphere to make it more engaging. To answer those questions and to show you how good doom guy must have been.
Aim?:
Makes monsters smarter than they used to be. What does that mean? No longer shooting through each other, no more infighting, no more shooting at props they can't attack through. Jumping off ledges to melee you. Providing shot spray to trick you into coming back out of cover. They CAN hear their allies die, get shot. They hear your shots along with your enemies. And more...
Enemies have the SAME DAMAGE you do! Yes that is very bad. But are you as tough as doom guy? He took them on anyway. They aren't overpowered either, you just can't let them sneak up on you/ know how to dodge/ don't get outnumbered/ holy crap.
Waiting for good news? You get 3 marines each map for you to call if you find yourself in a bad position. Yes it's that hard.
Even death match has a new tool. Random items are given to players when they respawn to spice it up a bit. Have fun.
The Name?:
Well it all started out as a mod to make the super shotgun shoot the right amount of bullets... I have no idea how this happened. Honestly.

All I can say is that actions speak louder than words. Give it a shot. And use cover.

Will Add screenshots later when I can get some good pics to show for you guys/ learn how to add screenshots.
Also its still somewhat in beta so credits aren't done and some things may change.
Screenshots: They don't really do the mod justice since it can't show AI, but here they are.
Spoiler:V1.1:
Player's armor increased just a bit.
Major AI Update:
Most enemies and allies can now jump.
All monsters now spray their attacks and don't follow you when out of sight. (spraying the place you just passed.)
Spectres can now be hit with bullets and melee, but pass through all actors including projectiles.
All gun enemies can now try to fake you out by halting their fire and then firing randomly again.
V1.2
A LOT smaller without all the beta stuff.
Credits finished, but might've forgot some authors.
Enemies attack slightly less.
Melee enemies are harder to back away from mid-swing.
Added varying difficulty levels to make it more bearable/harder than normal.
Players start with a rifle now.
Enemy attacking chances change defending on difficulty.
