My friends and I were playing Eggwars on the map Dwarven, when suddenly a player came to break our egg. We were trying to kill him, except he was taking no knock back. Also, while he was mining our obsidian, he broke the block behind him somehow. Then he broke our egg and all but one of us died. Then the last survivor on our team tried to hit the hacker off a bridge to mid with a punck 1 bow and arrow, except when our player hit the hacker, he took no knockback, then killed us. This players name is Bluesteel456. Here are some pictures. Here he is hit, but takes no knock back.
