My personal favourite followed very closely by 2. I ran campaign mode more times than I can remember on various 360 accounts. Pvp is going to be a different kind of beast with all the new players buying the game, just hope us "old soldiers" can still hold our own ;)

You'll be fine, it's like riding a bike, I never played MP on 360 (I never had a 360 but I played at a friend's) I just don't seem to know how to use that shotgun, I never use shotguns in games, the last shotgun I used seriously was on Titanfall because a challenge lol plus I seem to get matchmade with high level people and usually my team is just new people like me lol
