ughh! if i had to finish it 100% i would have considered it (considering i am at like 73% done and still have 5 outposts, 2 fortress's to take and 6 story missions) but fudge that, i aint gonna go trophy hunting.
I had about 70% completion I think. Its really easy to get the plat, just a few things you have to do in SP (a couple co-op) and you have to play some multiplayer.
