Update 1.03 for Red Dead Redemption 2 is available to download now on PlayStation 4. The patch weighs in at a reasonable 5.6GB, and according to its description on Sony's console, it provides "a range of miscellaneous improvements and big fixes for optimal performance". Of course, it also adds the Red Dead Online beta to the game.
Said beta goes live today (that's the 27th November) for those who purchased the Ultimate Edition of the game. We'll hopefully have some impressions for you in the near future.
