I made this mod with an ai platform called Cursor. It did all the coding, I just told it what to add, subract, or change.
This mod adds new crawling zombies to your world. They stay silent untill... SCREACH! They jump down on you from a dark wall or ceiling like a spider. They are fast and have custom walking and hitting animations. It can give you darkness if you aren't in direct sun light, and can break down doors. They also have custom loot tables.
