Watch Dogs multiplayer video leaked

A video showing off how multiplayer works in upcoming Watch Dogs has leaked online.

Ubisoft must have accidently published the video because it was quickly taken down, but not before other copies were re-uploaded.

It shows how protagonist Aiden Pearce has his game joined by a player-controlled character. He then has to find him to stop his operation.

Then things get switched up, and you become the hacker who has to go about his business without getting spotted.

Watch it below.

There's no word yet on whether players will be able to go about their single-player games without fear of others joining in.
