Got mine a few weeks back. Finished single player on normal in 3 days. Multiplayer is truly terrible I must admit, but like enfo said, its the single player that is the best. It feels like your actually killing someone, they way they blow up or get shot in the head and tumble about against objects. How your squad members move like real people and stuff. Its truly awesome single player.
But yeah, they should have made multiplayer more inviting, like co-op and more bots and stuff.
btw, not that I really have killed anyone before
