ReCore is an action-adventure shooter game played from a third-person view, centering around Joule and her robotic companions, whose function is to aid her in combat and puzzle solving; these six types of creatures are amenable to improvement, should players find the blueprints and materials to do so, which grants upgrades to their attack and defense. Players can level up Joule's weapons and vitality. Ranged weapons have four kinds of ammunition distinguished by color, each with a purpose to take down the enemy with a matching color. Furthermore, if one of Joule's companions matches the color of an enemy, it will thus inflict more damage in combat. Joule also wields a grappling hook that she uses to navigate across platforms and extract her enemies' energy cores. Removing a power core from one location to another and high-flying environmental challenges represent the puzzle solving.
