Ubistolen (Ubisoft's new secret game mission) | Side Operations Watch Dogs 2 guide, walkthrough
Last update: 12 December 2016
You can learn about the availability of the mission by eavesdropping on one of the informant's phone call (orange icons on the worldmap - the informant should be at Stanford). You will hear about a new game in development by Ubisoft San Francisco, and the objective will be to steal out a well-guarded trailer. This will be a simple quest consisting of a couple of rather simple hacking tasks.
You can now head to the Ubisoft HQ in San Francisco. After reaching the place, take a look around - search for the lift pictured above. Hack it and it will drive up to the building's wall. Get on the platform, and hack the thing again so it takes you as high as it can. This will allow you to get to the roof and reach a box that Marcus can hack.
After a successful hack, you will see the interior through one of the cameras. Hack subsequent cameras until you capture image from a big office shown on picture 1. Switch to the camera mounted on a big TV, then on the one in the smaller office in the next room, and finally onto the one in the laptop in the small office. This will let you find the computer shown on picture 2. Hack it to extract the trailer and finish the whole job. [+27000 followers].
