Cor blimey, guvnor, it's only a new Assassin's Creed Syndicate trailer. This one focuses on the overall plot, which seems to be: kill all the Templars. Business as usual, then.
I was a bit disappointed that the trailer didn't show us any more of Bloody Nora, leader of the Blighters - I swear I'm not making this up, google it. The new story trailer does show us some of the other cockney stereotypes whose faces we'll be stabbing, however.
They all have pretty forgetabble names, unfortunately. Crawford Starrick, the head of the Templar order, and his seven henchmen, are all bad men that need murdering. They control London, which is bad. So you have to take over his gangs and control London instead, which is fine.
It looks like there will be a bit of sibling rivalry between the twin protagonists at some point, too. My money is on the sister. Check out the trailer:
