        <Description>Luigi's Mansion 3 is an action-adventure game, in which players control the character of Luigi from a fixed third-person perspective, as they capture ghosts across a large hotel setting. The game features two modes of gameplay – a single-player story mode, and a set of multiplayer game modes – in which ghost catching functions in the same manner as previous installments: players stun ghosts with Luigi's flashlight, snag them with his Poltergust, and weaken their health down to 0 in order to capture them. </Description>
