Haha -- even assassins forget what floor they parked on sometimes!
This is a video of parkour pro Ronnie Shalvis dressed as Altaïr Ibn-La'Ahad from the Assassin's Creed series climbing up walls and jumping off buildings and doing flips and all kinda stuff that probably keeps his mom up at night worried sick about him. The video is actually pretty good though, and it's at least worth skipping around in HD. God, if I were him do you know how many times I would have rolled my ankles? Once -- at same time I broke both legs on the first jump.
Hit the jump for the video.
Thanks to Miles, who makes parkour look easy because he has rocketboots that look just like regular boots.
