The original Altair-led Assassin's Creed once featured a "huge" co-op component that was later cut to make way for Desmond's Animus-dipping storyline set in the present day, Ubisoft has revealed.
"Before we knew about the Desmond story and Animus link, we had a huge co-op component in there," said Bergeron, "but it just became too hard to do: the engine couldn't support it, and then the metaphor we had above it didn't support it."
"Co-op was one of those big things at the beginning that just didn't make sense in the end," added Bergeron. Assassin's Creed would later inherit a form of multiplayer in 2010 as part of Assassin's Creed: Brotherhood, the third game in the series.
Each subsequent game has also featured a multiplayer mode, but no game in the series has yet attempted to integrate co-op into the single-player campaigns.
"For us it was really part of the single player experience," said Bergeron, "to have in-and-out co-op, and in the end we never thought it made sense in the storyline that we had for the Animus."
"There was no way to reconcile having multiplayer or co-op in an ancestor's memories. Your ancestor lived his life in a certain way, so assuming you had branching storylines, it creates a paradox. It didn't fit."
The latest three-part chunk of Assassin's Creed III DLC, the single-player Tyranny of King Washington campaign that's separate from the main game, will kick off on February 19.
