Fortress in the middle of a wide open space of grass, the fort isn't very special, the fun part is that at night millions of monsters spawn because it is endless flat grass. If you ever feel like you haven't killed nearly enough monsters today, play this map for about 5 minutes and get yourself 100 kills! The inside of the fort is completely empty, so you decorate and customize it however you want! One problem however is that since it flat grass forever there is no way to collect resources of any kind :/ as long as you can spawn things on multiplayer or with toomanyitems then you have nothing!
