Coreless is a single-player third-person action game set in a sci-fi setting. The gameplay is based on a meta-progression system that allows for extensive protagonist customization. The player chooses an avatar and equips them with a set of skills and powers for battle. This approach opens up the possibility of creating different builds, such as spellcasters who attack from afar, melee warriors with magical talents, or assassins who summon minions to the battlefield to help them. Progression in Coreless is based on collecting resources during each run through the game’s levels. The materials obtained are invested in the research center and the store, which opens up access to new encounters and provides enhanced skills for equipping the protagonists.
