Watch Dogs: Legion

Royal Treatment is a side mission that will be automatically unlocked after completing 2 other side missions. The first one of them is called The Knowledge and will be given by Nowt at the safehouse at some point in the story. It’s recommended to pick an operative with good weapons as there are a lot of enemies. The second one, Nobody Home, will start automatically after the previous one, and once completed, Royal Treatment will start.

In this mission you need to find 3 abandoned mansions, you only have vague locations on the description of the mission but no marker.

The first one is located West of Warren Street Station, in Camden: You’ll need to solve a node puzzle and destroy a wall to hack the ctOS, and then photograph the mansion.



The second one is located between Horseferry Road and St James Station, in Westminster: Access the roof to hack the ctOS and then photograph the mansion.



The third one is located South of Westminster Abbey, in Westminster: You can hijack a camera on the roof and access the ctOS with a spiderbot that is available on the roof. Then photograph the mansion.



Then you’ll need to infiltrate Buckingham Mews.
