Three DLC packs for Dishonored are expected to launch starting this December with Dunwall City Trials DLC. The other two packs are scheduled to arrive in Spring and fall of 2013, Bethesda has just revealed.

According to the Bethblog, Dishonored: Dunwall City Trials which will arrive simultaneously on PlayStation 3, PC, and Xbox 360, will be released in 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 pack will introduce a new playable character named Daud, the head honcho of mystical assassins ‘The Whalers.’ He’ll have his own weapons, powers and gadgets, and you’ll get to roam around new areas of Dunwall. The yet-unnamed DLC is due in “spring 2013.”

Details for the third pack will be unveiled closer to launch.
