I need help with Halo 3:ODST!!!!!?

[Monsta T-Bagga]

Ok can somebody tell me why I can't go any further in the story, The last mission I beat is the "Oni Alpha Site" mission where you have to leave on the ship and when I beat it the game starts over and I have beat the game to this point twice thinking Bungie didn't get out of 1st grade but..apparently I was right. The game just keeps going back to the first mission. What is wrong with my game?

If I go to the main menu and click "Resume Solo Game" It just takes my back to the very first level. If I go to the main menu and click "Campaign" and the newest mission I can select is the one I have beat several times.
I agree with you..This game is awful.
Whats going on is that its restarting the whole story with the same thing going on everytime. I have went through the story twice already but it just keeps starting over once I beat the "Oni Alpha Site" mission

ODST is bugged and a horrible game, just sell it and buy a better game. Don't thumbs me down Halo fans because this is my opinion.
