Tactical Alliance Trinity is my clan. It's a primarily a three-man team.
Although the game is not the longest campaign we've seen, it is still fun, and I am going to have to throw in the disagree card on it not being what it's worth. You get the opportunity to unlock Recon, firefight mode for achievement gains with friends or solo, not to mention easy campaign achievements, a second disc with every map for Halo 3, as well as access to Halo 3 matchmaking, Reach Beta. If you regret buying it it's your own fault as you should have waited a couple days to rent it first.
