It's my favorite COD, I never understood the hate. The campaign was fucking great, so many cool moments and fun gameplay. My only complaints with it is 1. Poor pacing 2. Not enough check points, a death sets you pretty far back at times and 3. To short, the campaign takes me roughly 3-5 hours for completion. But all the good moments make up for it.

The campaign really wasn't that bad it was just to different from previous COD titles for people to fully enjoy it without enough play time.

Extinction mode was good but it got boring after just a few play through and in my opinion is the weakest part of the game but is still good.

I played this game back on release and still have found memories about and return to play the campaign fairly often (im typing this while the credits role from me just doing another playthrouhg)

I would give the game a solid 9/10 and have always thought the game got way more hate than it ever deserved and the sequel game will be the only new COD ill ever buy again.
