this pack mainly focuses on survival from the environment and zombies. you will need to get or making clean water, fight off hordes of zombies, and watch out for creepers as they explode no matter what and will rush whatever hole you are hiding in.
normal survival is just too boring and easy, it's just digging a hole and wait out the night. but this isn't your regular survival as zombies don't die in the day. you also won't be able to skip those zombies moaning outside your doors at night because some gained the ability to dig through blocks or their pals the creeper will blow a hole in your wall to help them out. "needs more stuff here"
"I'm honestly too lazy to keep writing stuff to make it more interesting. it's a hardcore-ish zombie survival what more is to say"
