Kingdom Hearts 3 and Re Mind is a role-playing adventure action game that is a large-scale crossover of numerous universes belonging to the Disney and Pixar studios. The development of the third part of the franchise was carried out by the Japanese division of Square Enix, which again brought together the worlds of Mickey Mouse, Goofy, Donald Duck, Riku and other cartoon characters with heroes invented specifically for Kingdom Hearts 3. The Remind expansion includes an additional storyline, 13 bosses, several challenges and additional difficulty levels.

The main character of the story, designed for single-player playthrough, is Sora, a little teenage boy who finds himself involved in various adventures. He, along with his friends Riku and Kairi, was preparing to travel to other worlds in search of new sensations, but found himself attacked by the forces of evil, which led to changes in the timelines of different worlds.

The third part of the series and the adventures of the heroes consists of the search for seven guards who will help in the battle with Master Xehanort – an antagonist who wants to disrupt the balance between the forces of light and darkness in order to carry out his villainous plans. Sora, Donald and Goofy will search for the guards, and for Riki and King Mickey another fate has been prepared – following in the footsteps of the former owners of the Keyblades – artifacts with sufficient power to defeat the enemy and save the world from destruction. The gameplay consists of numerous battles using combo attacks. For participating in battles, the protagonists receive experience points, which must be spent on leveling up.
