If you are in the process or finished completing Battlefield Bad Company something fun to do is search for colectable weapons and gold crates. On each msp there is a set number of gold crates and colectable guns to fund on each map. If you have an Xbox 360 you get acheivements for finding half and then all of the gold crates and colectable guns. If you have this game and you are looking for something to do this is something you can do.
