The anime and manga series One Piece inspired the creation of the video game One Piece: Unlimited Cruise 1 – The Treasure Beneath the Waves, an action-adventure game. Only the first half of a story will be continued in the next round, One Piece: Unlimited Cruise 2 – Awakening of a Hero. At the beginning of the game, the Straw Hat crew is sailing on the Sunny when they witness a glowing orb in the sky above them. They are now in the midst of a storm at sea. Luffy is dragged into the glowing ball as he gets closer, and once inside, he is informed that to get a reward that is commensurate with his efforts, he must first travel to the four islands of Dreams and overcome the challenges that are found there. When the crew is put through their paces, they are accompanied by a peculiar monster called Gabri.
The player assumes the role of one of the members of the Straw Hat gang while playing the game. Monkey D. Luffy, Roronoa Zoro, Nami, Usopp, Sanji, Tony, Tony Chopper, Nico Robin, Franky, and Brook are the individuals in question. The player must go to several islands and fight various monsters, including the game’s primary and secondary bosses. On the island, a variety of items can be unearthed and either put to immediate use or repurposed into something different through crafting. In addition, the player can break rocks with a pickaxe, catch fish with a fishing rod, and catch insects with a net.
