Ubisoft has announced a set of Assassin's Creed: Syndicate missions starring Dickens and Darwin, available if you pre-order the game.
As with everything in Assassin's Creed, the pair are wrapped up in some kind of conspiracy.
It's unknown if On the Origin of Species author Darwin and Victorian novelist Dickens will feature in the game outside of the pre-order bonus.
From the trailer below, the missions appear to be Ubisoft's most substantial pre-order bonus ever for an Assassin's Creed game.
Typically, the developer simply doles out exclusive gear to specific retailers and a handful of secondary missions for special editions.
All of this content is then wrapped up in a post-launch pack for those who wish to nab it all separately.
Take a look at the Dickens and Darwin Conspiracy below:
