The campaign was so-so. Too many stealth sections which I don't like in general, and particularly don't like in a CoD game where I just want to shoot shit. There was also some frustrating sequences where my squadmates turn to statues and do nothing while I get swarmed - namely Price at the end of the Ghost Team mission. The graphics are impressive though with some cool action sequences, with an interesting enough story to keep things moving, and gunplay is (not surprisingly) on point.
Moved on to MP and it wasn't as disastrous as I anticipated. I'm a filthy casual potato, but was able to manage a 1.0+ K/D in my first 4-5 matches and probably would have fared even better if I had a clue about any of these maps and wasn't getting constantly snuck up on. It helped that the campaign rewards you with a Union Guard M4 blueprint, so I didn't feel underpowered weapons-wise. I fully expect SBMM to kick in soon enough though and my geriatric ass will start getting stomped.
The UI, as many others have said, is a convoluted mess. I mean, why can't I even see any sort of timer on my XP tokens? Inexcusable oversight.
