Better than hating to be an Xbox user.

Halo 5 has a weak campaign for Halo standards, at least if you play alone. Especially the balancing on legendary simply sucks with A.I. teammates. That being said, it's not a bad campaign.
Multiplayer was and still is great, thoguh it might be tough to get into the PvP modes now. With Warzone Firefight though there's also a PvE mode.
