This is a mod I made for the modpack "We're Alive" that I'm making based on the fantastic podcast "We're Alive" which I recommend listening to if you want a fun take on zombies. I also reccomend you join the discord if you want to play the pack, I plan for it to be out in May.
PS. they attack all non hostile mobs and the player as well as being immune to sunlight as thats what I needed for my pack
