Not sure if any of you guys have heard of this but my buddy is on their environment art team so I'm trying to help spread the word. Any who Chivalry is made by the same guys who did the mod "Age of Chivalry".
Chivalry is a "first-person slasher with a focus on multi-player. Featuring competitive online combat that seeks to capture the experience of truly being on a medieval battlefield." and having seen it in action it looks pretty great, both visually and game play wise, and includes lovely decapitation. It's due to be released very soon but they need some help and don't have any real publisher backing. So check out their kickstarter page, back them if you so feel, hopefully it sounds like something some of you may be interested in.
