I mentioned this before and I'll mention it again - if anyone here has not played Shadows of the Damned, play it.
It is, BY FAR, the single best game on the Xbox that no one knows about or never played. It is an AAA class game that beats 90% of games I've played this gen - not kidding at all. It got great reviews (the only reviews not praising it are ones that didn't like the sick humor), everyone loves it, it has sick twisted humor, funny game, great musical score, awesome combat and boss fights, good length, solid story, great voice acting - this game is seriously badass and probably not that expensive because it sold like crap, because no one knew about it or bought it.
Play that game if you have nothing else to play right now.
