Whenever I play Dishonored, I imagine myself as Corvo. I think about what powers I would actually use, not what powers look fun, and base my playstyle off of those powers. But, in the Knife of Dunwall and Brigmore Witches, I try to get level 1 of every power except Void Gaze, Arcane Bond, and Summon Assassin because for those I get level 2. So that way, Arcane Bond is most useful to the Master Assassin I summon and he has at his disposal all the powers that Arcane Bond gives. It is probably my funnest way to play the DLC's, mostly because I just stock up on Piero's Remedy and let the Master Assassin do all the work. But I digress. How do YOU like to play Dishonored and its aforementioned DLC's? I want to see what aggressive, ruthless, and sometimes simple ways you play the game and used to finish it. Because you know that Master Miraak just LOVES a good tale of gorey, murderous assassins killing people for secretive and traitorous organizations (aka The Whalers and The Loyalists)!
Eh, I always try and go non-lethal and silent, but most of the time I just manage to get caught and then go on a slaughter rampage. As for powers, I mostly just rely on Blink, it's just far too useful and I don't think I've played a character without maxing it out. I haven't actually played the DLC for Dishonored 1, but it's something I plan to do before I pick up the sequel.
My "canon" playthrough is usually what I call "Assassin RP". It's a playthrough where I try and ghost through the entire level without being seen or even taken people down except for the main target who I will kill.
