Did you ever played Minecraft in peaceful before ? If yes, you should know that getting some material is very hard like getting strings or getting gunpowder.
Well this add-on makes it so you can play like peaceful but with all the hostile mobs included. But non of them will attack you.
No mobs will attack you. And you should play in hard difficulty. But some mobs like creeper and skeleton will attack you when you aggro them but, creeper will explode when you punch them.
If you find any bugs DM me in Twitter @RedIvationCraft and feel free to follow me.
