On April 30, MTV’s college network, mtvU, and the Kaiser Family Foundation launched a new online game that aims to tackle stereotypes surrounding HIV/AIDS, Reuters/Yahoo News reports (news.yahoo.com, 4/30).

The game, which can be found at PosorNot.com, was developed in partnership with POZ. It presents players with photographs of people of different ages, races and genders and asks them to guess if the individuals are HIV positive or negative.

Users can easily share the site with friends using an online link, a feature that the organizers hope will help spread the campaign’s message.

A number of celebrities have signed on to support the game, including Wyclef Jean, Alyssa Milano, Fall Out Boy and Will.i.am.
