Additional notes: Ranking system online is similar to BFBC2, and you can unlock suppressors for each AR/SMG weapon, not just a specific class.
Also, grenades are thrown as if your soldier is a little girl and the fuse on them seems to be 3 seconds, not 5.
Another one: the pacing of this game is much faster than BFBC2, but a tad slower than MW2.
***HUGE UPDATE***: The lag is beginning to surface, although not sure why. There also seems to be an invisible wall at times blocking your bullets... it seems random, though. Future update to come on whether or not it will heavily effect gameplay. Still a "buy" for me, but not if you are hard up for cash and are waiting on Black Op's or something.
