Red Dead Redemption 2 marks Rockstar's first new release since 2013's Grand Theft Auto V. The latter has proven to be an immense critical and commercial success for the studio, thanks to its perennially updated GTA Online mode and engrossing campaign, which follows three different characters that players switch between. But while having three protagonists worked well in GTA V, the feature won't return in Red Dead Redemption 2.

The Hollywood Reporter recently spoke with Josh Bass and Aaron Garbut, the art directors at Rockstar San Diego and Rockstar North, respectively. Among other things, the developers confirmed that, in contrast to GTA V's trio of protagonists, Arthur Morgan will be the only playable character in Red Dead Redemption 2.
