A recent update to Xbox360 Achievements has hinted that Ubisoft is developing more single-player content for Assassin’s Creed: Revelations. The new segments are likely to be first-person puzzles, while taking control of Desmond.
No price or release date has been announced, though retailers have been listing a game called Assassin’s Creed: Revelations – Ottoman Edition to be released on the 16th March, containing Free DLC. Around the same time last year Brotherhood released a Game of the Year Edition of bundling all DLC with the game, which means we may see the new DLC sometime until then.
