So, I just finished the campaign a second time (this time on PC). Boy. What a horrible campaign. Enemy AI is cheap as hell, they know exactly where you are at all times, they completely disregard your friendly AI team and will only shoot as soon as they see you. Extremely shitty deaths at times brought upon weird events that won't see coming unless you already played the campaign once or are retrying the level, that make dying in Dark Souls seem fair in comparison. While I don't expect realism in my video game FPS stories, the campaign was all over the place for me. All this sprinkled with shit QTEs on top.
Anyways, multiplayer is still fun as hell, but geez.
