Grab 6-8 friends and play! Choose a class and team, and spawn at your flagstand. Build a fortress around your flag in order to defend, and assault the enemy fortress and grab their flag. First team to get the enemy flag across the central river wins. Thanks!

P.S. Sorry that the spawn is not right, just turn on cheats and set your gamemode to creative. Then just fly straight up from the spawn and you'll be at the real spawnpoint.
