I don't think I have ever done a campaign. I only play online really, the Spec Ops on MW2 were good though. Quite enjoyed MW3 as well, but 2 has always been my favourite COD. If you have an Xbox One they have made the game backwards compatible now, so if you have the Xbox 360 disc it will work on Xbox One.
I have the modern warfare trilogy on my xbox one it came free with a newer COD. I've yet to play in on the xbox one but I'm toward the end pf Wildlands and will probably go through it again while I wait for RDR2. You should play through the campaign, great story.
Really? Didn't know they had released the MW games with a newer COD. I know they released the original MW with Infinite Warfare, but thought that was it. I've only got a PS4 and they are complete ****s about making stuff backwards compatible, so only hope I have is if they remaster Modern Warfare 2 and release it as a separate game or with a newer COD. Think Infinity Ward (the guys who made the modern warfare series) are scheduled to make next years COD so they might do it then. Also would love to play the fight night games again as they were great. ****y EA stopped making them in favour of a UFC game, which is **** and is a **** sport as well.
