Rockstar recently began to take the wraps off Red Dead Online, the separate online component of Red Dead Redemption 2 that will launch in beta a month after the main game. The roadmap sounds similar to that of GTA 5's GTA Online, given that Rockstar is already warning of some growing pains and signaling plans for long-term support with community feedback. The studio has also opened up about what it learned from GTA Online, and how this one will differ.
