Ok first off I laughed my head off at the opening cinematic - some tough looking dudes and explosions with a slo mo pass of the american flag, sooo shit it's unbelivable
[update] Ok, having played some games I agree with the general view here, it is fun. Combat is meaty and it mostly seems to work fine. One thing I would say I that I actually quiete enjoy some of the long pauses between combat, gives the game an almost tense edge to it (however the time it took to walk back to said combat zone was less fun).
Have a few issues though, firstly I know it's in beta so it won't be at it's best: Graphics, not amazing tbh, textures seem barely loaded at times. Also had some weird issues where it took several mashes of X for me to be allowed in a vehicle. Knifing still seems rubbish (BFBC2 had great knife mechanics, don't know why they swapped them for the generic CoD knife swing). and I don't like how the Back button has become battlelog, I like being able to instantly view the scoreboard.
Lastly I hope they improve destruction - all I could find to destroy was some windows and low walls, sure they have the big building falling down, but that's essentially prescripted - none of the other buildings could be damaged at all, I was at least hoping that a rocket would tear some chunks of out them.also, I found it curious the map was set in China, surely that makes the US the aggressor? (sure the story will find someway to justify it)
