Mario, Sonic and their friends take to the streets of London in this brand new trailer.

With the upcoming Mario & Sonic at the London 2012 Olympic Games Sega is offering gamers the chance to take to the streets of London as the iconic characters from both franchises in order to compete against each other.

The new trailer showcases exactly what the London streets will look like and they're certainly a bit more colourful than the real ones. With 50 party games available Sega promises that "the city is your playground" when the game is released on Wii on November 18th.
