Steam is chopping half off Arkane's Dishonored, bringing the price down to $29.99. The deal precedes next week's release of "The Knife of Dunwall," a new single-player add-on that explores a different assassin operating in parallel to the main game's plot.
In fiscally related news, Farming Simulator 2013 is also discounted by 50 percent to $13.99. Both deals have already started and they'll last through Monday morning.
Meanwhile, creepy indie charmer Limbo is on Steam sale for $2.50 until midnight.
