If this is redundant, please delete. But the loss of the old forums means the loss of lots of great images and visual guides that were once stored there. Maps, hiding spots, strategy guides, mine placements, MPC routes, you name it. A picture is worth 1000 words.
I only have two such images saved from back then, but I figure I’d re-upload them here, and maybe others have some to add? The kind of useful images you might have seen on the old forums and saved for later reference?
The first one is my sneaky Volcano Flyer Drone hiding spot. I would imagine that many people must have found it, but I’ve never seen anyone else use it. And I have never, ever been caught there 
And if someone does realize you’re up there, it’s tricky to get weapon damage to even reach you.
The easiest way to teleport up there is from standing on the stairs, I find.
The other is a map of deployable locations for Quarry. (I’d like to see similar maps for other locations, but I only have this one.) Seeing this led me to put my GDF radar farther forward than I had thought possible.
I found the best hiding place, but it’s almost impossible to get to without being noticed. You can hide on the vents above the final GDF spawn on Volcano, and no-one would ever check there either.
