Jumping off anything can be dangerous, even a chair in the sitting room, but leaping around rooftops is just madness, although parkour is great to watch. That is exactly what the guy (he's called Ronnie) in this viral video does, along with lots of somersaults, whilst pretending that he is playing a real-life video game of Assassin's Creed.
This is a massive viral video by YouTube standards, with well over 50 million views, while its account 'Devinsupertramp' boasts close to four millions subscribers, and rising. The film itself is really quite professional, although we're not sure why it keeps chopping between day and night so much.
At less than three minutes long, it is likely to leave you wanting more parkour, and if this is indeed the case, then why not watch the 'Behind the Scenes of Assassin's Creed' video that we've also added on this page? It is very interesting to learn a little bit about how this was filmed and produced - so much planning and preparation was involved.
