IGN sneak into Nintendo UK HQ to play the stages they didn't want them to see at Leipzig.
IGN writes: "During the Games Convention you may have seen our brief hands-on with Super Mario Galaxy. Although the demo was pretty much the same as we'd already seen at E3, there were also two 'secret' levels Nintendo didn't want us to play. Indeed, when IGN's intrepid reporter was spotted trying out one of these stages we were threatened with having a Wii-remote inserted somewhere quite nasty unless we immediately ceased and desisted. However, since then we've pulled a few strings to get some extended play-time on both levels, without so much as a death threat muttered in our ear".
