If you go to cosmodrome patrol you can go to the forgotten shore and past that to where the hive ship crashed down into earth. Now if you look their will be a big drainage pipe below the cliff. If you look it has the door of a vault their will also be 3 lvl28 fallen enemies. Their won't be a way for you to glitch your sparrow through the door but if you look their will be a small ledge to the left of the pipe. Get onto it and get your sparrow glitched into the wall and then you should see a cave that at the end of it their will be another vault door. Their is also a ghost their if you hadn't gotten it yet. Edit: Instead of arguing, why don't ya just go and glitch in, to and see for yourself. Then you can come to your own conclusion instead of just shutting me down with an ignorant bs. No offense to any one.
