Mr. E here, and i was playing in free mode, attack on ccity, as a heavy resistance fighter (wanted to try out chinzor), and i played max team 1 for mine, and max 0 for security. i went left, went down into the ship, and discover a wall jump area. after that, i replayed as a light body type, and finally managed to wall jump. i found myself in an area with a bar, a kabab stand, etc. after a bit more exploring, i found something odd. a SECOND resistance spwan point. it had a turret or two, and a command post, but i couldn't capture it, and it wa son standby mode. mabye this was the planned spawn area, but it they changed their minds and never deleted this area? mabye it's an easter egg. or mabye it's just the spawn point for another objective (thought of that just now). what do you think. am i being stupid, or is this something to look into?

Not sure about that spawn point, but when I start a game, waiting for centuries to see another human join in, I often run around and discover all sorts of cool spots...if Bethesda and Splash would try expanding this game a bit and adding TDM I'm sure a lot of these cool areas will be discovered and used by all. But until then, everyone will just be svcked straight to the objective and only use 10% of these maps.

where is this stuff i'm trying to find it. can you be more specific?

I'm not 100% sure based on your description but It sounds like the final Resistance spawn after Security have repaired the crane. It's actually a good way to go as a light if timed right, as you can flank the Resistance guarding the sample and get up on that high catwalk people like to snipe from.
