Wow, I did not expect this at all. This is a poor experience from the start. The battlelog web interface is terrible. You have to install all sorts of plugins and then wonder if your game is ready to start or not. The it launches in a window and gives you a tip - press alt + enter to go full screen. Why not just bloody launch in full screen.. Then it also switches back to a window when loading between maps.
You can't customise your options in the lobby, you have to be in the game standing doing nothing while you change your settings. Also - total game breaker for me - you can't map anything to the extra mouse buttons! WTF!?
I think I was the only one spotting anything too, and not once in 2 hours play did I get revived. It also seems really hard at first to tell whether you've killed someone or not as the placement of the alerts is unusual. Maybe it's the colour scheme or something but I have to make an effort to look at it to read it.
Why on earth did they put that Metro map as the beta?? It is basically a long tunnel which is the antithesis of what Battlefield is about. Maybe it will get better the more I play but I am seriously disappointed so far. If there are signs that BC2 will still have lots of players I may stick to that can cancel my pre order.
