Have continued with it and as suspected (and as previously experienced with Bad Company) it snowballs the more time you give it the more it gives back.
Highly addictive gameplay and cannot wait now for Oct 28th.
I love the bipod feature on most guns and how intuitive it is. If you are looking over a wall for example and then press left trigger to look down the sites, it automatically puts the bipod up.
The accoustics are good too particularly in the post metro outside area.
Its not without its faults however but this is to be expected in a beta e.g. sound drops out, when in the metro sounds from upstairs appear as though they are alongside you and also people upstairs can occasionally be seen through the ceiling!
Having to force myself to play BFBC2!
