Go to the PS3 section of the top players on Bad Company. If you click their MP Achievements page you'll noticed that noone has “I am Bad Company!” award.
From what I've heard they are working on a fix for this but I've invested quite a bit of time into the game already and have found that even if you could get the Platinum it would probably take you some 250+ hrs. Bad Company is a good game but I dont think I'll be getting the platinum for this one. I'd rather play some other games during those 250hrs. 🙂
