From Capcom:
This DLC content includes a side story about Rudy, whose family has served as Azurian Royal Palicoes for generations. During Rudy’s fur-midable adventures, he meets Navirou, the iconic Felyne from Monster Hunter Stories. Rangers will encounter Nergigante, the powerful Elder Dragon who is not the only challenging monster that Monster Hunter Stories 3 fans will face.
Additionally, a free update for the acclaimed RPG is launching alongside the Rudy DLC, which brings Royal Monsters to the field! This update adds a higher level of difficulty to the Final Battle for players with completed save files. Clearing the Final Battle on Hard unlocks Royal Monster versions of almost every creature in the game, including Invasive Monsters and Calamitous Elder Dragons, for Rangers seeking an added challenge.
