Zombies overhauled

You find yourself inside of a bunker stranded and lost, confused you look into a chest with very basic supplies, and you mine some cobblestone in your way. you climb up the ladder and embark on what you think is a peaceful world, but this is anything but peaceful. getting bit by vanilla zombies will give you 5 minutes to eat a gold apple or else you will become one of the dead. you must find shelter and hope to find other survivors who just like you are lost afraid and scared. but that's not all there isn't just zombies to worry about when it becomes nighttime you notice laughter and a pair of eyes, and it seems like they brought a little friend don't let them look at you to long or else???
