Red Dead Redemption 2 will come with a companion app, to further immerse you and your phone into the game.
The Red Dead Redemption 2 Companion App connects directly with your PlayStation 4 or Xbox One as you play, delivering real-time interactive information to your smart device. Available for download on 26th October on both iOS and Android, you can pan and zoom the map, set waypoints or mark areas of interest with a tap on your screen, aiding your exploration and discovery throughout the expansive world of Red Dead Redemption 2.
The app will also show you Arthur Morgan’s core info and stats in real-time on your device, allowing you to completely remove the in-game HUD from your television should you choose. Additionally, the Companion lets you examine Arthur’s in-game Journal, provides stat tracking through Social Club, contains the full digital game manual, plus an optional digital version of the Red Dead Redemption 2 Complete Official Guide from Piggyback and more.
