I played this game for two reasons: a) it's a halo game, and b) it was given free for X1.
Even though I like this kind of game, this one took me 6 months to beat, because some missions were too difficult to past through so I put the controller down for certain period of time.
Don't take me wrong, this is a great game. Just saying that If I choose the easiest difficulty is for a reason. I don't want to spend hours in a mission.
After playing Halo Master Chief Collection, I was more than motivated to complete this game. So I back, I beat missions E and F in a single sit.
If you are a Halo fan you should play this game. It looks great in 1080p very smooth though. Soundtrack is Ok and story good.
Play this game, it is a addition to the series that don't give so much. But good to play for a weekend. I think that the main purposes of the game is the co-op, that is the reason it was so difficult to me to beat. I have no friend with X1 here, so I had to play it alone which it is OK as well.
Thanks for reading.
