The first batch of DLC has been announced for the seminal, sandbox action game Dishonored. The first is titled Dishonored: Dunwall City Trials and is priced at £3.99 or 400 Microsoft points in a simultaneous release for PlayStation 3, Xbox 360 and PC.
It comes with an online leaderboard and new trophies and achievements and will test your mettle in combat and stealth in wave based arena combat. It sounds to be very similar to Arkham City's challenge maps, and are seemingly just to keep you playing the game for when the next two, story based DLC's drop in 2013.
The next DLC is based around the leader of a group of assassins called "the whalers" and their leader Daud. This will be much like the main campaign and your choices will affect the outcome.
The third DLC currently has no details.
