I have made a simple map called blind man where you are cursed with blindness and sent into an arena full of creepers with three of your friends and you will see who can survive the longest in arena full of creepers! Added a bonus round of you have no blindness or slowness but sent into an arena full of charged creepers! Pretty simple map. You should spawn in a butter/gold room if not try again until you do. Play on easy.

Rules can be found in the game also How to play. One rule forgot to put in No taking spawns from dispensers.
Command Blocks ON
Explosions (Anything) (Room made out of bedrock.)

Have fun.
