It's not that big of a deal, but it does get tiresome. If there were more levels like the prison -- where you can do large parts of it through stealth, then do a shortcut to leave -- things would've been a bit more enjoyable. Just walking into that derelict building, I was thinking, "Oh great, I'm going to have to go through a maze to reach that tower, then fight through 1000 guys who teleport over, just like usual". Glad to see I was mostly wrong for once.
Take me down from the ridge where the summer ends
And watch the city spread out just like a jet's flame
