Ubisoft has suggested that Assassin's Creed III will receive multiplayer DLC on a monthly basis, which will apparently further an evolving storyline as well as introducing new characters and maps.
Speaking to CVG, Ubisoft Annecy Game Director Damien Keiken revealed that fictional big bad Abstergo has turned the Animus technology into a commercial venture, which allows members of the public to experience the past in a full-immersion videogame. The multiplayer experience casts players as participants in the virtual bloodsport, with an overarching storyline evolving through episodic monthly updates.
"The multiplayer is so big today that it's already a game on its own. We've been given the right to develop the Abstergo storyline since the beginning, which is a big responsibility."
"Abstergo Entertainment will give you insights on the company's future initiatives by granting you access to files and information on products that will soon hit the market. As you progress in the game and level up your character, you access these files and videos. Every month you'll have new challenges to unlock new content that will continue the storyline throughout the year."
This ties in nicely with a rumoured Gamestop memo that ostensibly revealed an episodic DLC campaign and season pass. A canonical parallel storyline could well give Assassin's Creed III's multiplayer some serious legs, though it of course depends on how the content is doled out... and how much it will cost.
