Enjoy.

This is a review of the campaign. The multiplayer is still a buggy mess almost 9 months in. Personally, I really enjoyed the campaign and I feel like 343i did a really good job creating an open world game that still feels like Halo. The gameplay is super fun and the story is pretty good and had me tearing up in some parts. I would say that this is definitely the best Halo game 343i has produced, strictly in terms of campaign. I will say that Halo 3 and Reach set the bar fairly high, so 4 stars, plus it was missing a lot of key features that Halo games had at launch that are just now being added, like Campaign Co-op and mission replaying. Overall, still a decent Game in general with a very good Campaign.
