Ahead of this week's release of the first issue of Garnt Morrison's multiverse-spanning epic, The Multiversity, DC Entertainment has launched an interactive map of the multiverse for readers to familiarize themselves with.
Fans can visit the map and hover over any given Earth to get more information on what makes that Earth unique.
So far there's only information available for three earths - Earth-0, the main DC Comics universe, Earth-8, with a large population of superheroes who have come together to form the Retaliators, and Earth-23, home of U.S. President Calvin Ellis, who is secretly that world's Superman.
The site promises more earths will be added quickly, so keep an eye on that webpage for updates.
The Multiversity #1 goes on sale August 20.
