my sister recently bought an old 360 a few months ago and didn't get any games for it so when halo 4 came out she went and got it along with a controler. what was wierd was that she told me there was a glitch. there have been many problems with signing in on it but not that much note that she had bought the legendary edition and so she was able to get around the glitch by using the 14 day free trial for gold membership and beat the entire game however when i played it and not with a gold membership the glitch happened. what the glitch is is this: after about the second or third level where you first face off against hunters and master chief jumps into the first slip space portal in the game, right around the point where you see prometheans for the first time it begins to load the next level and then immediately kicks us back to the start menu. my sister(like an idiot) believes that the only way to get around it is to pay for gold membership however i do not want to just to finish the campaign and since we OWN the disc it would only make sense that we should be able to play it all the way through on campaign without any hassles we know the disc is not scratched because we tested it on our friends xbox and it works like a charm so the prob must be somewhere in the xbox's functions or the game not working right because of some programing error or something any feed back?
