If you're still an active Halo 2 gamer, Bungie has put out a couple of new matchmaking playlists for Halo 2 that are a bit interesting: Rumble Armory and Team ActionSack. I have to admit that I think the names are cool :).

Get the details here. Rumble Armory is unranked because it's so bizzare. I played a few of the new playlist games yesterday after work and they were a nice change from the same old slayer/ctf/BR/human games.
