I played the latest battlefield game on PS3.. It was all right but you can't deny the quick scoping in that game is a little over powered. That being said I pretty well always sniped in that game because being able to blow up buildings and create sight lines while your sniping was golden... =o)
And you can pretty well pad your stats in any game, even CF. Get your buddy to log on ever few days and whack his char thats useless. You used to catch ppl doing it in modern warefare 2 all the time in FFA trying to rank up their guns etc..
