This week's Red Dead Online update has been deployed to bring the Public Enemy event into the game. During Public Enemy, one player on each team is declare a persona non grata. The goal is to kill the opposite team's Public Enemy to score points.
In addition, the Free Roam Event this week is Railroad Baron where players "ride the rails and capture as many train cars" as possible. It is considered a variation on King of the Castle.
Lastly, the Bellerose Hat, Calhoun Bots, Raccoon Hat, and Shaffer Chaps are all available in the Wheeler, Rawson and Co. catalog.
