Just me playing mission 5 from sequence 4, which is a lair in Galata Tower. There are no spoilers, except for collecting the seal, if you consider that a spoiler. I chose this mission because it's an excellent display of the new freerunning mechanics with the hookblade and the heightened amount of cinematics (Uncharted style) in the game. Hope you enjoy the video.
Also, I will be posting the first exploit for Revelations soon, as well as a Desmond sequence.
