I don't think videogames get more steampunk than
Dishonored. Of course, it's not just steampunk, it's also the supernatural that looks to set
Dishonored apart from other
Bioshock-style "thinky" first person action games.
The following two videos show two different approaches to a mission called
The Golden Cat that requires you to assassinate two corrupt aristocrats ("Corrupt aristocrats" is probably a bit redundant in videogame land, donchathink?).
Whatever approach you prefer,
Dishonored is shaping up to be an exciting take on both stealth assassination games and first person action games. It comes out on October 9 in North America and October 12 in Europe for the Xbox 360, PC, and PS3.
