Rockstar is yet to announce Red Dead Redemption 2, but we may have some idea of its setting and scope thanks to a leaked map.
According to Techradar's source who is "close to the development of the new Red Dead," the map posted is real. According to this mysterious person, this is a "very recent" art direction map for Red Dead 2.
The game will be a prequel and set in an area just to the east of the original game. There doesn't seem to be a railroad, though the map does allow for one to be featured as part of its legend, while there are islands that may be accessible.
We may hear more about Red Dead Redemption 2 at E3 this year. But before you get too excited, that has been thought before.
