That aside, what is new in Halo: Campaign Evolved are the tweaks made to the core gameplay, which is entirely customisable. A Spirit flying above a Warthog next to a grassy cliff in Halo: Campaign Evolved. Master Chief wielding an assault rifle at a glowing orb in Halo: Campaign Evolved. Perhaps my biggest bugbear with Halo: Campaign Evolved is the art direction of the Forerunner architecture, though this is nothing new in the series. Overall, Halo: Campaign Evolved is absolutely fine.
