Finished the campaign, and my overall impression when it was all said and done was "safe." The story, relying once again on the covenant to provide one fork of a two-pronged threat, felt safe. The classic Halo level design and set pieces (drive out of exploding structure, tank level, flying stage) all felt incredibly familiar. It's a good game, after all the success of the Halo formula was proven time and again by Bungie, but no risks were taken in making Halo 4, no attempt was made to set the first game of this new trilogy apart from its predecessors. When it's all said and done, Halo 4 has a solid, lengthy, campaign and some decent character development for the enigmatic Chief and his AI partner, but the rest of the story is fairly uninteresting, squandered potential after the end of Halo 3. The game is still loads of fun in co-op, and luckily for 343i Halo's style isn't widely copied anymore, so if you're itching for some Halo, Halo 4 is your best choice, you'll have fun with it, even if it does feel very familiar.
