SNACK three-line summary
- The Rudy side story DLC and free update for Monster Hunter Stories 3 launched on June 26.
- The free update adds Royal Monsters and a high-difficulty final boss fight, while the Rudy side story is a separate side story involving Navirou and Nergigante.
- The standalone DLC price is not listed in the official article, so today’s news is mainly about checking the update for existing players and whether the added story is available to you.

Snackgirls editor note
Kirari: “For players who needed more to do after the ending, the addition of Royal Monsters should be the part they feel right away.”
Red: “The Rudy side story is paid DLC, but it is nice that the free update arrived alongside it. If you have already finished the main story, there is a clear reason to check in today.”
PlayStation Blog Japan announced that the free update and paid DLC Additional Side Story: Rudy for Monster Hunter Stories 3: Twisted Reflection launched on June 26, 2026. The same article explains that Navirou and Nergigante appear in the Rudy side story, while the free update adds stronger Royal Monsters for combat.
This is not just a simple event notice. For players who have already progressed through the main story, it directly changes what they can do after the ending.
What to check first in the free update
According to the official description, after updating the game to the latest version and loading clear data, players can challenge a high-difficulty final boss fight. Once that battle is cleared, stronger Royal Monsters will appear in each field and will also be recorded in the Monsterpedia with a crown icon.
In other words, this is a fairly direct change for players who finished the main story but wanted more from the training and battle loop. With Royal Monsters for areas such as flooded species and heaven-shifting Elder Dragons also mentioned, it feels less like a simple difficulty adjustment and more like new endgame hunting targets.

What kind of added story is the Rudy side story?
The paid DLC Rudy side story focuses on the roots of Rudy, the protagonist’s Palico companion. Both PlayStation Blog Japan and the global article name Navirou and Nergigante as key points.
However, the official article does not list a standalone price for the DLC. It says the content is unlocked for owners of the Deluxe Edition, Premium Deluxe Edition, and Deluxe Kit, so before purchasing, you should first compare the displayed price in your regional PlayStation Store with the edition you already own.

Why update now?
The advantage of this patch is that paid DLC and free content are moving together. Even if you are still deciding whether to buy the story DLC, the free update alone lets you check the high-difficulty boss and Royal Monsters first.
In short, the key points to watch today are the June 26 launch, the Rudy side story DLC, and the free Royal Monsters update. If you have cleared the main story, it makes sense to update first and check the endgame changes, then decide on the Rudy side story after confirming the price and your owned edition.
