This is NOT London. I know the London Eye and Big Ben might be confusing you, but note how this area has NO buildings at all besides huge landmarks. And a pro-tip for all you non-UK anons, Blackpool Tower is not in London.

What you are seeing is the post-game facilities, which seem to be made up of UK Landmarks. The actual "London" city is the steampunk one in the middle of the region where England is actually located in the UK.
