I wasn’t even trying to break out of the map but I went the west-most part of the EDZ map, entered the Cabal base, reached the strike map where you usually take the first energy orb and dunk it, and then used grapple to climb up onto some missles crane-suspended from a platform, and then hopped up and out.
What’s REALLY cool is this time I found a functional area with systems. It wasn’t textures matured or anything, but there were ships being built in a shipyard, and some were coming in for landings. I didn’t see any disassembly, but the assembly and take offs were cool!
I need kept exploring the area and found a cool tower and got as close to the Shard of the Traveler as I have ever gotten while outside a mission.
