Wait... *looks at calendar* *confirmed It's September 2015* *reads topic title again* Wut?

You can stay in the doorway before the boss. There are vandals and captains that will spawn from the room on the left and you have to fight them, but you can run back inside and run down the stairs. I think the two best spots are there or what the other poster said about going up the stairs on the left and going through the window. Hope that helps

Oh you're a new born
