Recently, modders DickHertz and Tuffy returned to Red Dead Redemption 2 and introduced a modification that activates some hidden features in the game (left by Rockstar Games itself).
Thanks to this project, RDR 2 players can access unused elements on the map or those that were tied to specific missions. Some were made by the modders themselves, but most are original work by Rockstar.
For example, Blackwater has a working port that will receive cargo, tourists will appear on weekends, and the Saint Denis art gallery is open to guests.
The "A Dynamic World" mod for Red Dead Redemption 2 is distributed for free via Nexus Mods.
