Capcom has released another major update for Monster Hunter World. Update 3.0 is now available for PS4 and Xbox One, and it introduces some significant additions to the game, including a new Elder Dragon, quest type, and more.

The centerpiece of the update is the new Elder Dragon, Kulve Taroth, a fearsome monster with a golden mantle made of weapon relics. Kulve Taroth can be encountered in a new area called the Caverns of El Dorado, which Capcom describes as "a peculiar network of caverns shaped and influenced both by the Everstream and the minerals that Kulve Taroth has collected over the years."
