Batman: Arkham City - The Demon's trials and Ra's al Ghul boss fight (New game plus)

[WARNING: THIS VIDEO CONTAINS MINOR SPOILERS FROM THE MAIN STORY OF BATMAN: ARKHAM CITY]
This video features the whole Demon's trials sequence inside Wonder City in Batman: Arkham City and the boss fight against Ra's al Ghul immediately following. Notice how I recorded this gameplay while playing on New game plus difficulty.
The Demon's trials are basically an obstacle course where you are tasked with mastering the whole gliding-and-diving mechanic with Batman's cape. While not that difficult, you will die if you do as much as getting a bit far from the trail you are given.
Ra's al Ghul may as well be the best boss fight from Arkham City (I mean, among the combat-oriented bosses) and isn't that challenging, provided you can take the right steps. Ra's crowd form is easy to deal with if you managed to get the assassin enemies' pattern down at this point, while his illusion form is a bit harder to deal with (thanks to you never knowing for sure if you'll be able to dodge that attack or will find yourself in it). I found out that, in the latter's case, sprinting is far better than dodging

I just can not get over how Batman is doing the beat down on this man so hard his sword lodges in the ground. then back hands him away from it, grabs Ra's head, and hits it on the sword hilt. Magnificent animation!
