The Mob Arena minigame is playable both as singleplayer and as a co-op team game. To join a battle in the new arena simply type /ma join stadium
You will then be transported to the arena lobby from where you can choose your warrior class and then ready up, at which point you will be dropped into the arena itself where you will then fight to the death against endless waves of different mobs.
You can also spectate a game in progress by typing /ma spec stadium
To exit the arena (either as a player or a spectator) at any time just type /ma leave
There is a scoreboard for the arena located in the castle at /spawn, this will show the stats either for the last game played in the arena or for the current game in progress.
N.B. The commands will NOT work on the creative world, so you'll need to be on the survival or factions worlds to use them. Also, the minigame should automatically store your inventory and then return it to you (with any Mob Arena reward items) as soon as you type /ma leave
Any questions, problems, or issues, please do let me know.
