As might be expected from the next generation of Assassin's Creed game, if you buy the game before its released and perhaps even before it's entirely finished, you'll gain access to some of the period's greatest minds, meeting up at some point with both Charles Dickens and Charles Darwin, both of whom are digitally represented in the game.
The trailer doesn't exactly make it clear whether these too well respected individuals will show up in the main game, or just in bonus missions for those that pre-ordered the game, but they do have their own story line, known as the Darwin and Dickens Conspiracy. It seems to involve a "dangerous plant," that may threaten the lives of everyone in London.
As you might expect, you're the only one that seems ready to help.
Of course though, if you don't want to pre-order - and judging by the state of the last AC game when it was released, you shouldn't - this pack will also be bundled up in a buyable bit of DLC post-launch, though pricing information has yet to be announced.
What do you think of the upcoming Assassin's Creed: Syndicate?
