Mario and Sonic at the London 2012 Olympic Games takes inspiration from all corners of both companies' history: screenshots have reminded us of Yoshi Story, Sonic Adventure and more. But we've just received more screenshots showing the most universe-shaking crossover yet.

Mario and Sonic at the London 2012 Olympic Games on Wii, with all its hedgehogs-in-space madness, is out next week. The 3DS version is released in February 2012.
