I'm very new to decorate so to learn I made a mod that tweaks almost all of the enemies (I left the arch-vile alone) to make them more interesting. The idea was to tweak the monsters just enough for your strategy to have to change but without altering the core Doom feel. Things like cacos having a lower painchance so you can't chainsaw them easily. One of the main goals was the keep the game balanced. It is harder so I don't know if ultra-hard wads would be doable. This is definitely a WIP and I would love critiques.
Screenshots can't show much as I wanted to use all the standard Doom assets to keep the feel the same but here are some anyways
