Was wondering why I didn't have infiltration mode unlocked from uplay. Turns out you actually have to go into uplay from the game you unlocked it for even if you unlocked it while playing another game. Well all is good and I'm playing infiltration mode which is a real pain with all the guards, trip wires, motion sensors, etc. (most of which weren't aren't even in the rest of the game).
I also acquired all the extra guns, costumes, and gadgets. Ubisoft gets respect from me for giving them out for free because any other company would have charged 3 bucks for each item individually when all they did was draw up some costumes (and bring back some old ones), guns, etc. and put them in the game.
