The MP is a breath of fresh air compared to the other games I play online, Gears and BF3. It's nice to actually have to think about your next mode of attack, rather than just: See enemy, right trigger, see enemy, right trigger, repeat 30x.
Successfully flanking someone is also 10x more rewarding than other shooters. Once you sneak up on someone in cover, and they have no idea you're there, that's when it gets exciting. Take your time, line up the headshot, double tap. Most of the time I find myself in situations like this with only 3 rounds left, so if you get it wrong, you're dead. 👍
