I thought it was a great ending to a great game. the game had everything halo fans like in the series while adding new elements as well. This made it feel both nostalgic and fresh at the same time. I felt like the whole game was really well done but at the same time, I feel that there are not enough new features and game play elements to bring new players into the series so if your a halo hater, this game probably wont convince you to like halo, but if you are a fan of the series then this is the definitive halo experience.
I wasn't sure about one thing though, when you see noble 6's helmet on the ground, the weather is nice, and you see a ship in the background. Is that after the events of halo 3?
