personally i found C2, though fun enough gameplay wise to warrant replays, to be pretty much entirely inferior to 1. the things i liked better about 2 were being able to shoot silenced weapons in stealth mode, stealth kills, and the armor mode actually acting like it increased your armor. i also rather liked the single-press suit mode buttons, but i'd gladly give those up for all 4 modes and leaning back.
i AM a little curious as to how they attempt to rectify the stories, but i know i won't accept it as anything more than damage control for how terribad 2 was. won't be buying this until it's both cheap and available outside of origin. which may mean never but oh well.
