90%? I don't think so... just some of them:
GamingTrend::
campaign is top-notch
Gaming Age:
I’m going to avoid story spoilers in this review, but I really enjoyed the overall campaign plot, more so than I did in Halo 4. The ending, in particular, could lead to some really interesting places for Halo as a whole, and I’m certainly looking forward to seeing where things go from here.
BestGamerEver:
he campaign is a confident, well told, galaxy spanning adventure with a huge amount of replayability on a scale we’ve never seen.
Game Over Online:
the core campaign, and in multiplayer, it all works to create a better experience for the player. The stories of the Halo franchise began somewhat simple, with many things explained and a lot of things left in the dark. The expanded universe explored in books helped fill in gaps, while the later entries were more story-driven. Halo 4 took this to new extremes with CGI, and Halo 5 keeps that trend alive.
