I’m a member of the Halo Insider program and played the test flight last weekend. I’ve seen others receive codes to give their friends the ability to play this weekend but I have yet to receive one. I have a friend who plays through PC that would like to play, so I’m trying to figure out a way to give him access.
Same here, I’d like one as well. It does indeed seem that a lot of other people on Insider have not received a “buddy invite” mail yet, so do not fret : )
