Hong Kong is one of those crazy future cities in the world where buildings kiss the sky and people are stacked on top of people and streets hide alleys which hide labyrinths which hide awesome. It's great. It's also great for climbing to the top of a skyscraper to hijack a billboard. These guys proved that.
This adventure-filled video (it's a fun watch, trust me) shows them navigating the streets, exploring the city and climbing to the very top of the building right in the middle of Hong Kong (I'm not going to lie, my knees went weak a couple of times). Once they gain control of the billboard, they beam videos of themselves and ask 'What's Up Hong Kong?'.
