Cruel is a gamemode that exist in the game , alongside with creative , adventure , Challenging , and harmless gamemode

Cruel Gamemode is basically similiar to Challenging which you need to survive , animal may attack you unprovoked ( if they are predator ). but if you die on this gamemode , you cannot respawn , whenever you try to respawn , you just redirected to the menu

you are able to play multiplayer ( via split screen ) in cruel mode , but you can't add new player once the world is made , you could only add new player during the start of the world
