This map is a polygon with fortifications at one end of which your spawn, and another enemy spawn Mobs. You need to select allowance of ammunition or arrow or war.
To collect as many different levels by killing mobs ways, traps do, compete with friends. Map is under Beta-testing all bugs write in comments.
1) do not break any blocks
2) if the ammunition is over you can turn on God and fill the chest
