Logging in with your Bethesda.net account will get you the following new modes in both Dishonored 2 and Death of the Outsider:
Take a trip back in time to any previously completed mission from the campaign and experiment freely with all powers and weapons.
### Black and White
Feeling moody? Black and White mode lets you experience the game in a new visual style. This filter does exactly what it says on the tin, but all blood will remain red. See? Moody. You can toggle between Black and White mode and the original color mode at any time.
In addition to these two new modes, Dishonored 2 players who log in with their Bethesda.net account will also gain access to the original pre-order bonus, the Imperial Assassin’s Pack. When you stop by the Dreadful Wale, you’ll find all the bonus items in the pack waiting for you in your cabin.The Imperial Assassin’s Pack includes:
Duelist’s Luck bone charm
Void Favor bone charm
In-game Antique Serkonan Guitar for Emily or Corvo to interact with
In-game book: Goodbye, Karnaca – A Musician’s Farewell
500 bonus coins
I never finished Dishonored 2 and it's definitely one of those games that I always think about going back and playing through. I was playing as Emily and it felt like I eventually specced myself in such a way that I was really good at sneaking around but not at dealing with guards and since I play these games in no-kill and no-detection mode that made things pretty complicated when there were groups of enemies I couldn't get past. But maybe I'll tackle it someday!
