Hey! Today I helped create a 1.13.2 mob arena map! The head creator is Ashley33, her YouTube is Golden Gamer Girl: https://www.youtube.com/channel/UCWaQGU-CJMDvuGkRcx39Q_g - This is a two player game, one player spawns the mobs using a system called "Ultra Spawn" and the other fights the mobs spawned in the arena. Make sure to download this map and check out Golden Gamer Girl's video on the map! Cya!
