WWE (World Wresting Entertainment) Raw is a wrestling TV program on the USA Network. Here we have one of their frequent arenas recreated in the world of Minecraft. The build is quite big and can hold hundreds of players if the player limit allowed it. In the center of the arena is the wrestling ring where the contestants have to fight one another to win the match and game title.
Perhaps you can use this map to make a similar wrestling challenge in Minecraft PE. It’s surely a unique map.
