Everyone who enjoys playing Halo 3 on Xbox Live should join the Anstice Brigade, an ODST based Halo clan. Those who join the Brigade are individuals who like a militaristic type of clan structure, but also like a place that is secure, active, and never loses its "fun" quality and that's what the Brigade tries to maintain. The brigade participates in a local UNSCDF tournament ladder against other ODST, Marine, and Spartan clans, but also participates in the online clan matches (if applicable by bungie). I joined 6 months ago and find it a very enjoyable atmosphere to play in, plus you get to play with people who COMMUNICATE during game play and work together. There is nothing more annoying than playing an objective mathch with people who do their own thing. if you are interested, follow this
