Klei Entertainment have announced they are bringing DLC to Mark Of The Ninja. due to public demand, they tried to create special DLC which they modeled on the "Criterion Collection". no price has been announced, but it will come this summer and be the Mark Of The Ninja: Special Edition.
The Special Edition DLC Includes:
> A new level, set in a flashback to
the early life of Dosan (the ninja’s tattoo artist) that will set
the stage for the events that transpire in Mark of the Ninja.
> A new style of play, which
includes a nonlethal takedown ability, and provides a hybrid of
lethal and nonlethal approaches to the game.
> Two new items, one more geared to
stealth and concealment and one a bit more direct. Both the items and
the new play style will be available in the main game as well as the
new level. (more details at a later date).
> Finally, we’ve added a
ton of developer commentary to the main game. All the original levels
will feature a number of commentary nodes that discuss various
aspects of the game’s creation, anecdotes, at least two history
lessons and other behind the scenes info from nearly everyone on the
team.
> Developer commentary has been
fully localized for English, French, Italian, German, Spanish, and
Japanese. (Which our amazing community has helped us to translate)
