Also, let me just say that the visuals in Halo 2 Anniversary campaign have FAR exceeded my expectations. I wouldn't change A THING. This is an anniversary done right. I wish they could overhaul the Combat Evolved anniversary with some of the assets from this one.
This game gets EVERYTHING right. I find myself having more fun than I ever did on my initial playthrough of Halo 2. I think the remastered visuals and audio make every aspect of gameplay more satisfying. From tearing through Flood with a shotgun has never been more satisfying, or enjoyable. I even enjoy fighting Brutes now, which is something I can't say for the original Halo 2.
I think my favorite touch so far has been the remastered audio for Hunters (which look a hundred times more menacing and formidable in this remake. Pressing back for old visuals on them is mind boggling.) Every step they take booms, like a fucking pair of tyrannosaurus that are about to fuck your shit up!
I just wish CEA had taken this approach. The contrast in art direction between that anniversary and this one is blatantly obvious. It seemed like CEA just injected assets from numerous pre-existing games and called it a day. H2A, however, went the distance and really hit a home run, visually.
