Easily the best game in the series, I really enjoyed Reach and 2A but this blows them both out of the water honestly. The combination of the more linear classic type of levels and the open world while playing as the rookie is perfect. Many of the missions give you more freedom to do things differently. For example you can choose to take the covenant head on or you could go into a nearby building and find a sniper on a balcony. Many of the missions have details like that to make it that much more enjoyable to play. While the story did not really have much connection to the Master Chief story the setup of having the team separated and then each mission is them trying to get back together was unique and interesting. I genuinley had fun playing each mission (not something I can say for the other Halo games) and I look forward to replaying this one and finding all the hidden details and ways to complete missions.
