How can the government reach out to teenagers to stop them romping without wearing condoms? Make a videogame-inspired campaign for YouTube, obviously.

Game On!, a video, parodies Mario and Mega Man as a boy searches a side-scrolling level for a condom. If he reaches the end without one, he'll blow everything.

Along the way he'll need to avoid slipping into a an alcohol bottle (green pipe) and being hit by STI monsters, which look more or less like the baddies in Mario.

The campaign is the brainchild of Leicester's branch of the government's Teenage Pregnancy Strategy, an initiative set up in 1999 to "dramatically reduce" the number of teenage pregnancies in the UK.
