Post your gamertag below or send me an Xbox Live message or Friend Request if you want to unlock some campaign or spartan ops achievements with me!
My Gamertag is: DeT Phantom
Also, for some wild reason if anybody wants to get some Halo 3 achievements, I will be more than willing to go and play through the game on legendary with 4 player co-op, for I have not gotten the achievement on my new LIVE account…
