Dishonored developer Arkane Studios returns for part 3 of it’s documentary series on the same, which explores how the team went about crafting different elements of the title. This time, they talk about experience, and how “the game’s flexible combat systems allow you to play to your individual style and craft your own experience”.
This is aside from the depth and far-reaching effects of player choices though. So yes, deciding to kill an enemy with his own bullet or rat consumption does matter.
Dishonored will be available for release on the Xbox 360, PlayStation 3, and PC this October.
