This map created to make fun with your friends. you have 5 unique arenas that have their cons and pros for the 6 kits you and your friends can choose. the kits have their mission too, one can fight at long range while other kits can't, but theres a counter for long range kits, etc. and your mission is to protect your nexus in the base by any cost, you can do that by building fortifications, and fighting.
the map is for 1.14+, 2 - 8 players. you can add more players if you wish, but I think 8 its the most comfortable choice.
