The thing nobody has mentioned here is that you have a certain amount of time to get TO that door. This is something new...and unmentioned apparently. One of the mods here on the forums said it's about an 8 minute timer. If you get there just a little shy, you can actually watch the door close. In other words, go faster than you've ever gone before. GL

Yes, it's still obtainable. After oryx takes the ogre and you have to run, no one in the fire team can die. If someone dies, the door closes. Good luck, this is still one of the most challenging missions/weapons to complete/obtain in destiny.

First, just saving you time but you won't be able to solo this. After you successfully get to the door the mission requires you to go through the Skolas mission, killing multiple rooms of shielded taken centurions and wizards. Then you have to defeat a taken captain version of Skolas, while also clearing the entire room of ads, all of that in 10 minutes or less. (There's a timer.) You should try to have 3 people. As a previous poster said, "this is one of the hardest missions in the game." Second, No one in the fireteam can die before you get to the door. So you must book ass through the tomb husk rooms, and get to that door asap, alive! Third, if at all possible use bubble titans and swords. Once you're in the last room the best strategy I've found is having at least 2 bubble titans and everyone using exotic swords. You can lay the bubble at the ultras feet and everyone can jump in start slashing away in the bubble. You can die in this section, in fact your whole fireteam can die and it won't restart, but the timer will continue to count down while you wait 30 seconds to respawn, and if you don't kill everything you'll have to start the entire mission over from the beginning. There are other strategies out there you can look at, but I've found the sword strat to be the best.
