Red Dead Redemption 2 is finally releasing in two days on PlayStation 4 and Xbox One, and Rockstar Games confirmed today that more than just the game will be released on October 26th.

Alongside Red Dead Redemption 2, Rockstar Games will release a companion app on the App Store and Google Play Store. Through the app, players will be able to check out the map, a diary with relevant information and even move the HUD completely on the smart device, freeing space on the main screen.
