So because of the SUPER EXTRA EARLY MIDNIGHT RELEASE, I only got to try two multiplayer matches. Can we stop it with these ridiculous "early" release dates already? Why would you release a big new game on a Monday morning? Wouldn't Friday have made much more sense? -Anyway-
Playing two matches isn't enough to really form an opinion on this, other than one thing-- the game already shits all over CoD Ghosts, but that really isn't saying much.

The game feels like the same post-Modern Warfare CoD that we're all familiar with, but you get added 'super jumps' via jetpacks and can now click the analog stick to do a small quick dash. This gives you a lot more mobility and makes it possible to dodge fire in ways not possible in the other CoD games. Some people already hate this because it apparently kills the sniper game, to which I say
GOOD. You also get extra abilities from the exosuits like a power boot or an energy shield that can be generated, which appears to have replaced riot shields.

There is also a classic playlist offered, which ditches all these extra abilities, so it's kind of like having two games in one.
The two maps I tried felt tighter and better-designed than anything in Ghosts. It was nice to start playing and not get immediately slaughtered by someone on the other team camping the spawn points or get shot from a sniper from all the way across the map.
Is this TEH BESTS COD EVAR?!?! No idea. Have already seen mixed opinions from people, although I feel like this can't be judged so quickly since it just came out and the people who were playing it early were doing so without several patches applied. The added abilities definitely raise the skill level required to do really well, which I like a lot.
I definitely like it more than Titanfall already, though. Just not a fan of those giant mechs and minions.
Graphics are "okay". I mean the frame rate is the most important thing anyway and I don't really care about graphics but I don't think these are the kind to blow people away anyway. It doesn't look remotely as good as say Destiny obviously but then I'll always take a higher frame rate over better graphics.
All these CoD games have pretty much looked the same in MP since Modern Warfare. That said, I remember being impressed with the way that factory level in Ghosts looked and so far haven't seen anything like that in this game.
