Welcome to Pokémon Castaway! The player is the (not-so) fortunate winner of a trip to Alola. On the flight there, however, the plane is struck down. Landing on the mysterious Bermada Island, the player is tasked with exploring their environment while searching for fellow survivors and a way off of the island. As the player traverses further inland, it becomes evident that the island is anything but deserted. Will the player find a way off the island? And, more importantly, will they get to go on an Alolan vacation?
