Nice, one or two I didn't know about here. The only one I feel you left out was at 1:55, on defence if you're trying to round this corner you can jump over the 3 stacked barrels and avoid a lot of fire. Not necessarily a short-cut but a good tip
Nice and useful, I didn't know some of these shortcuts. Although, I know two more shortcuts that you didn't add (not the one with the barrels). I can't really explain it, but I just wanna say that there's more. (:
theres 2 more spots you need to be aware when playing the spy that you did not mention, albeit not much of shortcuts but still very usefull, on the map room after you jump out the window try and fall on the stairs so you dont break your fall and notify the enemy of your presence, also on the left side if you jump down on top of the lower rail you dont take damage, eather way nice vid
none of these are "shortcuts" these are places you can stand on barely any are even useful and most of the useful ones are hard to get to and by the time you get there the enemy will have caught up to you
