Arkane Studios and Bethesda have released a new developer diary for Dishonored, which shows off how the game was conceived. The clip reveals early concept art and explains what the team was shooting for when they first came up with the initial concepts.

In addition to providing insight into the game's development, it's also a great place to start if you haven't been following any previous coverage. As co-creative director Harvey Smith says, it's the first first-person game focused on a supernatural assassin (in a steampunk-inspired world). It's probably a good time to do your homework.
