It would appear all did not go well after Emily was reinstated on the throne at the end of the first game following Corvo's maniacal killing spree (or completely peaceful revolution – but who seriously took that route?).
This time around you get to play as either Corvo or a grown up Emily, again choosing from a variety of different ways to complete levels using stealth, magic abilities, ranged attacks, melee, or a combination of them all.
The downtrodden industrial revolution feel of the first game was just absolutely nailed, and I for one am greatly looking forward to returning to this opened-ended series. Hopefully we'll get a character just as disturbing (and intriguing) as Granny Rags, and its a good bet based on the teasers released so far that there will be entirely new powers to use in unexpected ways while haunting the rooftops in search of prey.
