I try low chaos its hard avoiding towers and tall boys of all the enemies and bosses I hate the stilt walkers. Though I'm on a second playthrough and its all ready different several ways. Though I question the relationship between the emperess and corvo. XD
There is Auto of the Empress putting out there that she did love Emily and Corvo. Ohhh, Corvo has nads to sleep with her. Wouldn't surprise me that he's the father. Lmfao, I hauled ass on Low chaos. Used my Blink, and slow time.
No matter wht I tried I kept getting high chaos. And it was brought up several times through audio bits through journal entries through books even npcs have mentioned it not too mention that part in the beginningt when emily sais mother missed you shell be glad to see you've returned.
