So 3 friends and I just did the halo reach campaign on legendary difficulty in 2 hours and 50 minutes…2 of them got the calling card my other friend and I did not. I would like to know if you can give us the card possibly? You can check play history and see that we all did it together! If not well then that sucks I wasted almost 3 hours of my life and have nothing to show for it.
Load up a mission and run through it again. That should solve your problem.
