Campaign: Ha-ha REALLY lacking ever since Halo: CE but it served its purpose into growing the gamerscore and making me e-penis so much bigger. Lol.
Multiplayer: Multiplayer is amazing however, it can use some work in terms of community. I think this youtube video will sum up my own words for you in a more comical way. So, enjoy.
