Ubisoft has released a new trailer for upcoming open world tech thriller Watch Dogs 2, introducing the core cast of characters including the members of hacker group DeadSec who will help protagonist Marcus Holloway take down a shady conglomerate.

The Welcome To DedSec trailer (above) sets out a story about the shady Blume Corporation, which is profiting from the trading of private information collected from local businesses and directly from the citizens of San Francisco and other cities around the world.

In a post on the PlayStation Blog, Ubisoft's Chris Watter's wrote about the game's heroes: "The protagonist, Marcus Holloway, has already stopped a mass surveillance initiative in Oakland using his unique set of skills.

"Sitara and her principled, artistic approach may not always vibe with Wrench and his aggressive, chaotic style, but there's no doubt that both are passionate, driving forces fuelling DedSec's efforts. In this trailer, we also get a glimpse of Josh and Horatio, two other members that make up the DedSec crew.

"With a powerful array of hacking tools at your disposal and the open world of the San Francisco Bay Area at your feet, you and your fellow hackers will do whatever is necessary to stop Blume and their new, improved ctOS 2.0 from infringing on the freedoms of the citizens."

ctOS is the name of the city-wide operating system that gives the game its central concept: the ability to manipulate a city's infrastructure and the technology within it. Players are able to create pile-ups by changing traffic lights (to evade the police perhaps), raise and lower bollards, control cars and much more.

Watch Dogs 2 builds on the foundation laid by the original, which while successful commercially, suffered creatively thanks in part to its loft ambitions and lengthy marketing cycle. Where its story was drab and its characters unlikable or forgettable, the sequel appears to have a much more prevalent sense of fun.

The game was announced in June and will be released on 15 November for PS4, Xbox One and PC.
