So, the way this would work would be that there is just a regular survival map (with barriers), and it would have around 10-12 players. The way you play in Minecraft is, you have a map with Minecraft items on it, and the first person to get 5 items in a row on that map, would win the game, there is also full house mode, where the first person to get everything on the map, wins the game. I will try and post a image of what the map looks like.
