Great for a new challenging game experience, however it was not too informative on how to actually begin and not die. Some sort of advancement tree that explains the new features would be very helpful.
This is a great hardcore datapack, it changes survival mode in a way that I hadn't really seen before. If you've been playing regular survival mode for a while and want a challenge, I definitely recommend trying out this datapack! It's quite a treat when you have a group of people. If you die, a zombie spawns with a good amount of health and damage creating a zombie infection chain reaction.
