Hey I love old games and love to mod them, like Duke Nukem 3D and Doom! Oh and my profile is not related to the Moon Man Doom mod. I don't like that mod, MY profile has McTonight because I like McDonald's since I am American and loves diabetes.
Currently recent mod here:
Nobody Told Me About id (NTMAi) is a Doom mod by Can't Sleep that changes the game to look like a Build Engine game.
NTMAi is based of Build Engine games like Duke Nukem 3D, Shadow Warrior 1997, and Blood 1997. In the classic Doom games, the guns are in the center, NTMAi places the gun model to the right and has a melee button like Duke Nukem. You can even set the enemies' AI to the enemy AI from the Build games.
There are weapon changes too, the pistol now reloads, the chain gun has new textures, there's a tommy gun, flame thrower, a spell book, claw, grenades, mighty foot, etc.
This mod is my favorite because I loved playing Shadow Warrior since it was free (the 1997 one) when I first got Steam. I enjoyed a lot of the features NTMAi has to offer that I don't want to spoil it for you!
