With Halo 4 just around the corner a few friends and I are attempting to get all achievements before halo 4 hits and we are having great difficulty, either through lack of oppertunity or just bad luck.
We are playing all halo titles as we still have a few to get done across all the games, if anyone is interested in helping out or is looking for help feel free to message me 
reply back so I know you read this message.
