I like to play singleplayers before I get into the multiplayer aspect of games ; to me it just seems more respectful by doing so, for the developers. But, this games singleplayer is, to me, not playable. I played 2-3 hours of it and first of all, it's not very fun, Secondly, the game has major FPS lag issues (in singleplayer) , Thirdly, it's just very repetitive. The Multiplayer ,on the other hand, is revolutionary. I never played anything like it. It's a mix of all my favourite games : Uncharted ( for its stunning parkour), Call of Duty (for it's near flawless gun play) and Halo ( for its SCI- FI awesomeness). If this game had a better campaign, it would possibly in my top 3 favourite games of all time. This game is meant for any FPS fans, SCI-FI fans, Multiplayer fans, Uncharted fans. It's a must get if you are truly a gamer
