Infamous: Second Son - Glitch Outside of the Map (Original)

So I came across this accidentally when I was playing Infamous: Second Son today on PS4. I haven't figured it out exactly, but when I try the following few steps a few times it leads to surprisingly consistent results. 1) Go to the place marked on the map. It's a huge building with the electrical wiring coming out. 2) Find the concave spot on the building with the rubble sticking out. 3) Using *NEON*, run up the wall on the inner left concave part. 4) When the electricity bumps you back, keep running up the wall in the same spot (you may need to try a few times). 5) You're outside of the map. Have fun!
