Dishonored: Dunwall City Trials DLC Coming This December; two story-driven DLCs coming in 2013

Bethesda has officially announced its DLC plans for Dishonored. Dishonored: Dunwall City Trials is the first DLC that is scheduled for release this December (for $4.99 or 400 Microsoft Points), and will include 10 challenge maps that will test and track your combat, stealth and mobility skills.
Ten distinct trials await challengers – including an arena battle against waves of enemy AI, a gravity-defying run of drop assassinations, and a race against the clock. Dunwall City Trials also features a whole new set of achievements and trophies as well as a global online leaderboard that will establish the greatest assassins for each challenge.
The second and third add-ons for Dishonored will be coming in 2013 and will each feature story-driven campaigns. Even though we do not know their prices, we do know that they’ll hit all platforms at the same time. In other words, no platform exclusivity deals like those of Battlefield 3 and Call of Duty: Black Ops 2.
Daud, the leader of a group of supernatural assassins known as ‘The Whalers’, will be the focus of the second add-on pack, scheduled for release in early Spring 2013. Make your way through new Dunwall locales and discover Daud’s own set of weapons, powers and gadgets in this story-driven campaign. How you play and the choices you make will impact the final outcome…
Additional story details on the third add-on pack will be revealed closer to its launch next year.
