Bethesda has today announced that the stealthy first-person steampunk title Dishonored will be set to receive three DLC packs, with the first one being available in December. The first one to arrive will be called Dunwall City Trials, and will allow players to compete against 10 distinct challenges.

Dishonored: Dunwall City Trials, being released in December for AUD$8.45 (or 400 Microsoft Points), 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 DLC pack will be available December for $8.45 (800 Microsoft Points) and will be released simultaneously on all platforms.

Bethesda has also revealed details on the second DLC pack, which will be focused on story-driven campaigns. The DLC will focus on Daud, the leader of a group of supernatural assassins named 'The Whalers'. The DLC will be available sometime in Spring 2013. The third DLC has yet to be announced.
