The free-to-play game was first announced in 2017, when it was called Pokéland. According to an information page, this is the same game, but with a new name. The game builds on the Pokémon Rumble series, which launched in 2009. Past iterations have appeared on 3DS and Wii U, and Pokémon Rumble Rush shouldn't stray too far from the rest of the beat 'em up series -- it was created by the same developer, Ambrella. Unfortunately, we don't know yet when the game will appear outside of Australia.
