Chivalry may be dead, but Chivalry: Medieval Warfare lives. I'm in love with this game and thanks to a recent patch it's gotten a lot of its buggy weirdness worked out. If you're not willing to spend a couple bucks getting one of last year's most delightful indie games, then you can go and try it for free thanks to a rather giving weekend on Steam.
