I'm just glad this time I knew beforehand that I'd be playing as Locke in this campaign alongside Chief. Although I figured half the campaign would be played as MC and half would be Locke, or it would be as close to even as possible. That doesn't seem to be the case but that's alright, it should be less jarring than Halo 2 when it switched perspective each time I completed one of those short 'two part' levels. Hated that.
Anyway Locke seems ok from what I saw of him in Nightfall and in trailers and stuff. And I knew going into this game that I'd be playing as both characters, so that helped me accept it better. My issue with Arby back in Halo 2 was he was such an unpleasant surprise to me. In the trailers it looked like the campaign was going to be this epic battle for earth, but instead there was a short stint where we fought in earth's orbit followed by another stint on the ground, and that was it for that. Bungie and deception go together like -Yoink- and tissues.
