this game has been pissing me off lately. Everytime i have about 2 more waves to go for the endure achievements. It says someone quit, and clearly everyone was there. This has happened to me about 6-7 times. I have heard it happening to others as well. I think bungie is playing a sick game of watching us cry when they see us waste 2+ hours on this achievement, just to find out we have FAILED. lol
Yes you do get another armor when ODST comes out in september 22nd.I see it in a Bungie.net forum right now. And modding you Halo 3 ODST achievements will NOT get you recon, I made an accnt hoping it would but sadly it didn't. The gamertag is ReCoN4SeLL you can add it and check its achievements and service record.
