I need to unlock the M13c as AR's are pretty easy to platinum so should be a relatively easy one to do.
Up to 42 platinums now, so only 9 to go - single digits baby! Basically just continued working through the SMG's and Marksman rifles. Marksman, I think, I've only got the Tempus Torrent to finish but I've got most done already. SMG's I'm working on the PDSW and about halfway done with, I think, only the BAS-P and Fennec left to do but I imagine they're going to be horrendous for thinking I need to play some hardcore for them.
That puts me at 46 total, add the M13c, FR Advancer and Carrack is 49. So need to find a couple more......hmmmmm. Battle rifles suck but maybe hardcore? Launchers maybe? But I think I'm track to have plats finished by MW3.
