Million dollar game fell off the face of the planet?

So, my friend is thinking of a video game that has to do with space, and you can do SO MUCH stuff with super powers (it's not star wars) and stuff, and it was for xbox original.

The catch is that the game manufacturers offered tons of prizes like a million dollars or something like that if people found the glitch that they put in there, or something like that. He wasn't too sure of the details. But he swears the game existed, and they had a massive recall on the game, and now it's completely gone.

I've spent the past half hour looking for it on google and turned up nothing. Any ideas?
