Bethesda today announced Dishonored: Dunwall City Trials, the first DLC for its well-reviewed supernatural stealth assassin adventure game Dishonored.

Dunwall City Trials will be released sometime in December and will feature 10 challenge maps that, according to Bethesda, will test players’ combat, stealth, and mobility skills. The maps will include “a gravity-defying run of drop assassinations” and an arena in which players will battle waves of enemies. The DLC will also feature new achievements/trophies and a global leaderboard for players to compare their skills.

Dunwall City Trials will cost 400 Microsoft Points via Xbox LIVE or $5 via PlayStation Network and PC.

Bethesda also today stated that the second and third DLC for Dishonored will be coming next year. Those add-ons will feature story-driven campaigns rather than challenge maps. The second DLC story will focus on Daud, allowing players to experience new locations in Dunwall. Bethesda implied that players will actually take on the role of Daud, who will have a different set of powers, weapons, and gadgets than Corvo.

This is exciting news for players who loved the stealth action of Dishonored, but found the length of the title lacking. A set of challenge maps should provide some more replay value and get the player community using their assassin skills in creative ways.
