Game is great, story was fine, there was a lot of repetition, boss rooms were the same, hallways especially were the same, large chambers with firefights were the same, to the point where the last mission just felt like a waste of time. Also lots of weird pointless walking through hallways that were just repetitions of previous hallways... It gets a 2 star because of the 25 minute unskippable end credit scene.
It's no classic Halo, but it has an okay feel to it, though I felt the master chief was less powerful
