Error Game

I bought Halo 5 Guardians on 11/12/2015 and completed the campaign on my own in under 5 hours.
The story line to the campaign was gust awful, it was all over the place, the campaign just made me feel like putting the controller down and forgetting that it ever EXISTED.
Online Multiplayer War Games- I was exspecting more but where do I start, loadouts dont exsited like they did in Halo 4, the armour cannot be unlocked by ranks or tasks anymore, less colours for custom armour as well, all armour that you do onlock looks the same, this mess of a recreation of halo 5 that so called gamers love is a mess, I was told to save my £50 and not buy this game but I bought it as this is Halo franchise that I LOVED and now I just want to cry down the phone to Microsoft demanding my money back for this game.
This game has killed I for me, as far as I am concerned Halo universe died at Halo 4.
