Thought it was going to be a different experience, I found myself just repeating the same level over and over again because I didn't have any motivation to move forward in the story, I just wanted to kill some aliens while listening to a monstrous soundtrack, which is amazing btw, and even that wasn't enough to get me to keep playing it... Might try to replay it sometime later, or even try the sequel, because from what I've heard and see, it's a better experience overall.
