Campaign was okay. Outside of that the Multiplayer is pretty much trash. Sprint, no de-scope, classes/perks, rank system is outside of the game only and means nothing(45+ gets matched up with<10 players), maps are sub-par to awful with the exception of a couple, etc. There is a reason this Halo died quicker than all of the other Halo's and that is because the multiplayer failed. People told 343 for months in the forums things that should be added/included in the game and they didn't try to add them until they realized their game was a failure. Can't say enough bad things about it. Pick it up used for the campaign at best.
