These guild wars can last anywhere from a single day to a fortnight, throughout which the involved guilds' members will be free to gank one another to their hearts' content. Not a guild kind of person? Don't worry! Free agents can be hired on as mercenaries if they wish to join the fray. And if the guilds don't want to fight it out to the bitter end, the system also includes ways to negotiate a surrender or declare a stalemate, all the while tracking each guild's stats on a leaderboard. So get out there, don your halos and horns, and start killing one another! After all, you're already in purgatory anyway.
