So I turn on Halo3 unlock the Recon armor. completed the achievements and stuff. i turn it on last night and all the sudden, my recon is gone?! i disconnected the xbox from the wireless the other day, and it was there before i disconnected it, but now it is gone??? CAN ANYONE HELP ME PLEASE?!
Who knows where it might be. I have heard of a couple of cases like this that occured when 343 made it available to all. I would just wait till the EXP is working again and maybe 343 will do something productive and get it back for you.
Recon will not show up offline, you have to be connected to Xbox LIVE for it to show up, it has been like this since September 2007.
