Hm... this inspires me.
Now that it seems the ship area is actually part of the main map and not a separated instance.
Does make me wonder if the Stillwater instance is also hidden somewhere beneath the ocean floor, there's a whole lotta map to cover.
Currently looking into what happens when you call a vehicle and leave the simulation as you are ported into it.
The Xor (since the video used this as well) transferred along with me, just couldn't do anything.
I'll be testing this with a Tank now, see if I can really do some damage.
ADDIT:
It seems the ground vehicles port you too fast.
The Void (alien VTOL) can be ported out, this explodes, and blasted me on top of the ship, see attached shot.
Of course, there's not a whole lot you can do without superpowers or access to a new vehicle since those parts are still disabled. But hey, it's something. At least we know you can get out from within, now to get within from without.
