Damnit, why did they have to go and show almost all of my favorite routes ?
Oh well atleast the video didnt show a few of them.
Anyways this is pretty much how I always play the game, and I can tell you it is definatly much more rewarding then just running and gunning on the floor.
I will how ever say I am suprised I don't see you use the jump from while hanging on a ledge to another ledge behind it. Its extremly effective for maps such as aquarium, you can really get the drop on someone if you can do it quickly.
Also theres a very nice jump from the Crane in container city, to the containers close to res spawn.
Edit: almost forgot to applaud the music, its a great match.
