Ok, so you know when you are facing Oryx? And that a knight spawn out of a ship( the knight with the aura). Well, if you jump on the ship and stay on it until it disappears in the wall across the room, you are going to float on an invisible platform and the ennemies can't shoot at you but if you move a little bit forward, you can shoot some of them. I tried it a couple of times to confirm it was the real thing but I haven't tried to cheese with it so I'll leave it to you guys, even though Bungie will probably patch it... have a good day fellow raiders!
