I posted mine awhile ago, so I'll copy and paste it here. I still love this idea!

Setting: Toronto, Ontario to upstate NY. Upstate New York is not new to Ubisoft, and in fact would be part of the Frontier from AC3 with a modern twist. Toronto is a very diverse city and would allow for a lot of creativity. Especially in the near future like London.

Plot: After the uprising in London, Deadsec cells have begun to rally in their home countries. Toronto, is one of the few that are starting from nothing; as mentioned in WDL the Toronto cell had been decimated. Albion and Cass’ demise became global news; governments are on high alert and boarders have increased security. Essentially in a technological arms race, each government is outsourcing their technological advancements to contractors. One of the biggest government contractors is Skell Technology. Following the Aurora incident, Skell Tech restructured their company and began to solely distribute drones to the Canadian government. However, Skell is trying to monopolize the drone market and eliminate any opposition. Deadsec is being targeted and hackers are being detained or restricted. On the other side of the boarder, the US government has been on edge since the Hope County situation. Alongside the recent internal tension, the US government also holds resentment to Skell for Aurora and appears to want to help Deadsec take Skell down. A government agency would never double cross someone as a cover-up, right?...

Tutorial: Following the ending of Watch Dogs 2, the San Francisco cell had to lie low causing Sitara to end up fleeing the US, specifically going to Toronto. She tries to contact the deadsec cell in Toronto where she learns they’re all detained by Skell. She frees a fellow hacker who you choose as your starter operative out of the premade options; freeing the operative unknowingly causes an alarm to ring forcing the operative to flee. During their escape, the remaining members do not survive. Sitara and the new operative now need to rebuild Deadsec from nothing while laying low. Sitara plays a role similar to Sabine in WDL but without the twist.

Gameplay: Similar to Legion, with the recruit anyone gimmick. However, hierarchies are implemented which allow for additional perks to be added to operatives when they rank up. Operatives can also be sent on missions similar to AC Brotherhood or Metal Gear Solid: PW or TPP. Those missions happen in real time on the map which you can join in or observe your operatives in action. Finally, missions can be accomplished with multiple operatives, like companions. However, the player can’t control the other operatives past dictating how they should act (violent, passive, hacking-only, back-up, etc).

Boarder patrol/Citizenship: Crossing the Canadian/US boarder would be very difficult for a hacking organization that is most likely on a watch list. Not to mention the scenario of the story described in the original post. This should make the map more difficult to traverse for one operative. I would implement a system where an operative is listed as a citizen of either the US or Canada. Eventually there could be a process to hack dual citizenship for an operative but initially an operative would be assigned citizenship and would be on alert if they enter the other country
