Pokémon Legends: Arceus just received a free update called Daybreak, which is available now.
Version 1.1.0 of the game introduces story content which has players looking into a strange phenomenon causing mass outbreaks of Pokémon across the Hisui Region. Footage shown during the February 27 Pokémon Presents broadcast revealed groups of Hisuian Growlithe and Zoroark as well as Empoleon and others gathering across the region.
Daybreak also gives players the chance to engage in new battles with their allied Pokémon in the camp training grounds. Additionally, as a Pokémon Day gift, players can enter the code ARCEUSADVENTURE to receive 30 Ultra Balls, Gigaton Balls, and Jet Balls. This gift is available through March 31.
