While searching high and low for locations on highly rumoured 6th and 7th raid chests, me and a buddy were exploring the jumping puzzle area. We discovered that while near certain lights the controller vibration pulses and the screen shakes a little. Now i'm not one for playing with rumble or anything but I found this interesting. The screen shaking defiantly has something to do with the rumble. One of the first noticeable lights is above the walkway when you first land down from the normal jumping puzzle, stand next to it and the rumble starts pulsing. But what is this slight shaking of the screen? Think of the mission on the moon "Shrine of oryx" Closing in on the final area you meet an angry ogre that roars and shakes your screen! Now in the vault, theres nothing in that area though...So the next thought would be on the other side of the walls. The gatekeeper is a floating hydra though, and atheon is not summoned yet...So is there some creature/vex that is stomping around somewhere? And do these lights hold a secret code to them? Or are these rumblings a glitch? Who knows......
