I'm past the halfway mark of the campaign. Spent all my time there an haven't touched horde or multi yet. I will post a review later, but who's playing it?
***Please do not post any campaign spoilers***
Current thoughts: JD Fenix is a good new frontman with his light hearted sarcasm. Del makes a good new sidekick. They're no Marcus and Dom, but still have good synergy. More like Cole and Baird, if Baird wasn't so sarcastic and Cole was toned down in the beef an energy department. I want to like Kait, but something feels off. She needs more lines beyond serious dialogue.
ETA: Beat the campaign, and what an ending. Kait is now 1,000% more interesting. All the reviews warned of a lackluster ending, and the boss fight is rather forgettable. Wasn't expecting that end twist. Much better story than the Halo 3 - Halo 4 switch. Excellent continuation of the gears storyline.
