Nearly finished everything for Tom Clancy's Splinter Cell Blacklist (PS3). Hardest difficulty, no kills, all collectibles etc...but I still need one more mp related trophy (Support Ops) and haven't done a weekly challenge yet The daily challenge I did was pretty easy, think it was 50 (or something) sniper kills that I did offline solo in some missions. Weekly challenges that I've seen over the last couple of weeks have been mp kills, mp kill assists and stuff like that so I'm just checking to see what else pops up.

I was surprised to notice that most of the mandatory co-op missions were possible solo (with a second controller idle most of the time), although there were a couple of spots that needed two active players to proceed
