Question--why did the timer start when they wanted it to, and not when they touched down like any other Destiny speedrun? I know that first door is at least ten seconds, and the Darkness Zone doesn't trigger until they get near the first island.

There is a glitch (feature? Copy DE right now Bungie, please!) where if you jump with Boost Glide and melee with a sword (it used to just be the Hive Sword, I think, but some other swords can replicate it), it launches you like you see in the video. I don't really know the specifics, but I saw that info in a comment in the reddit thread.

I also saw mention of being able to use the Warlock grenade that you can charge up to increase your glide by quite a bit somehow, but the player here wasn't doing that.

The basic mechanic, as I understand it, is that the Warlock glide inherits your current momentum. That’s why it usually feels so slow; because the movement speed in Destiny is so slow, and the warlock’s jumps add no or very little momentum the way Titan and Hunter jumps do (Hunter jumps give a burst of speed *upward*, which doesn’t help much with traversal speed).

So the trick involves using the Exotic Braytec sword’s lunge move to generate a split-second burst of speed, and then immediately use the Warlock glide to maintain and carry that speed over great distances.

You can see a Hunter use this same trick to launch himself through the air while activating his Golden Gun in this video (at roughly the 20 second mark):

Ridiculously impressive. Wow.

The POV we’re following in this video is incredible, but I also want to see what his 2 teammates were doing to melt both the Ogre and the final boss near-instantaneously O_o

I'd like to know that as well. They're both using Whisper on the final boss, but I don't understand how he went from 50% health to nothing basically instantly.

The guy who posted the video replied to me on reddit:

“For ogre, tractor cannon and mountaintops (and one bottom tree nova bomb). For last boss, whispers.”

So apparently, while the Warlock was glitching down through the floor and flying through the whole first half of the dungeon, the other 2 players were legit completing the maze section. They had to complete it before the lead dude reached the Ogre boss. So they beat the maze in... ~4 minutes? Unreal.

This is absolutely incredible. I just cannot even imagine playing at this level.
