If you've ever spent an unproductive half-hour banging on about how awesome Assassin's Creed would be, given the ability to invade another player's campaign world, you probably won't be all that chuffed to hear that such a feature once existed.
According to Assassin's Creed 3 mission director Philippe Bergeron, the original Assassin's Creed once sported an ambitious co-op mode, which was eventually cut. "Before we knew about the Desmond story and Animus link, we had a huge co-op component in there," he told OXM during our scintillating series retrospective "The History Boys", published in issue 95 (on sale now).
"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," Bergeron admitted.
"For us it was really part of the single player experience, 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," he went on.
"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."
Assassin's Creed has ventured into multiplayer waters since, of course - Assassin's Creed 2 spin-off Brotherhood gave us a worthwhile cat-and-mouse affair, conducted on distinct, sealed-off maps that are just as conveniently well-populated as the single player variety.
But it's hard not to want more, in light of such feats of companionable stealthing as fellow Ubi release Ghost Recon: Future Soldier. Rumours has it that Assassin's Creed 4 could be a fully co-op supported return to revolutionary America. Sounds good to us.
