Tour London with Nathan Drake as Your Guide

There's lots to see and do in London – but the English capital's way better when Nathan Drake's your guide. Three's partnered with Sony to create an "innovative, real-life adventure" whereby various landmarks across the city have been tagged with Nolan North audio clips. With the use of a unique smartphone app, you'll be able to listen in on these, which include cryptic clues for the next destination. The first person to complete the treasure hunt will win a PlayStation 4, with other gifts up for grabs.

The first clue and additional instructions can be found through here. In truth, this is all part of a promotional partnership between the Japanese giant and the popular network provider, which will see the price of the PlayStation 4 dramatically reduced if you happen to buy an Xperia Z5 or Xperia Z5 Compact from Three. Advertising it may be, but you can never have too much Nolan North in your lives – get scouting the city.
