This morning while on patrol on Earth, I went to the original Loot Cave. I was just poking around looking for Spinmetal. Inside the cave was a pile of remains and I had the option to disturb it. I held down Square and a voice began echoing through the cave with an eerie message. I've searched the internet, albeit shallowly, and I haven't found anything about this, yet. I only heard the words, nothing else happened. I've spent some time at The Loot Cave and never seen this. It is Halloween season, so maybe it is a small nod to our holiday. I'm curious if anyone has seen something similar elsewhere?
