Here's something awesome: a Dishonored gameplay demo from E3 2012.
Raphael Colontonio and Harvey Smith, co-creative directors of Dishonored, gave Morgan Webb a look at thier upcoming steampunk thriller set in what can only be described as an alternate reality London-esque city. Colontonio and Smith go into great detail about gameplay, including the pros and cons of sneaking vs. straight-up murdering everyone, as well as creative ways that players can combine powers to get awesome kills.
This game look so unbelievably awesome that it almost hurts, and Morgan Webb agrees. October 9 can't come soon enough.
