Not pictured: Donkey Kong, getting shouted at

SEGA's Mario & Sonic at the London 2012 Olympic Games uses just about every input the 3DS has to offer, but it's the weightlifting event that looks to make best use of the machine's microphone.

As the new trailer below shows, you can shout at your character to give them an extra bit of power. While it might make you look a bit odd out in public, it's only helping a necktie-wearing gorilla to win an Olympic medal; nothing that could get you committed.

North American 3DS owners can get a free trial of the game next week as part of the 3DS demo download program.
