Access to a New Area on Sunder Discovered.... off the main game path
I found btw a way to get off the main path of the slideway you are on for the story, i think it is a undiscovered bug...but you can jump from the main slideway area to the lower slideway and explore more of the amazing city world....and it did not appear to cause any harm in my progress, just be sure to save before this point.... I will hide it with a spoiler
Spoiler:You get to the spot where the floating man is, and after he does his thing if you complete the conversation he flies off, stand just by where he was and you can jump over and down to the lower slideway and your companions will follow you safely too. You can move around and see some areas that are inacessible from view above. Fun discovery. Enjoy.
BE SURE TO SAVE YOUR GAME BEFORE TAKING THIS DETOUR, YOU WONT BE ABLE TO GET BACK TO THE MAIN GAME PATH FROM THERE...SO THIS IS A ONE WAY SIGHTSEEING TRIP as far as i know, i did not try accessing either end of the walkway did not want to break the game.
you jump down from here....
and this is the lower slideway you see from above but cant get to ....usually.
