Fanon:Ultra Boss Mode

Ultra Boss Mode is a game mode in which teams of players both attack each other and fight extra powerful bosses that spawn with great regularity.

Technical

 * There are two teams in Ultra Boss Mode—red and blue. Their bases are square, like those in 4 Teams, and are located in opposite corners of the map, as far as possible from each other.
 * Polygons award twice as much XP.
 * Normal Bosses spawn every five minutes, even if there is an Ultra or Infinite boss in the server.
 * Ultra Bosses spawn every twenty minutes, unless there is one in the server.
 * Infinite Bosses spawn very rarely (5% chance or so) in place of Ultra Bosses.
 * The game ends when an Ultra Boss or Infinite Boss is killed.
 * When an Infinite Boss spawns, all players become part of Blue Team and both bases vanish.
 * After being killed three times by a Boss (not by a Player or Pentagon), the player can no longer return to that server.
 * The leaderboard shows ten people who have the most "Boss XP". The XP that a Boss awards goes into this. Also, 1 damage to a boss = 1 boss XP.
 * The base Protectors never attack Bosses, though Bosses are prevented from going on bases.
 * The Pentagon Nest has a vastly increased chance to spawn Green Polygons.
