One star doesn't do it justice. The lack of content is terrible. The repetitive game play is annoying. The constant search for material is infuriating. The end game content needs more substance. If they took the time to fix the bugs and extended the release date it would be a much better game. The boss fights are just as repetitive as fighting the regular enemies. It takes forever to find other players to play with and no one has a mic to make this somewhat more enjoyable.
If you're debating on getting this game I suggest you don't.
