First off the game itself is ok. Story isn't wholely engaging at all but some great visuals. However... It ia buggy. It crashes the xbox and then will not load the game. The fix is to lose all of your recent progress and go back to an old save. Can happen at random times. A real shame as there was potential here. And i have always been a halo fan. Will think twice id they bring out any more. Google bugs and you will see it over the web.
