The co-op details have not been announced, yet.
The original 3DS-Version allowed for up to 4 players work together as multicolored Luigi's to explore the special "Scarescraper" tower. Three co-op modes are available to choose from: "Hunter", "Rush", and "Polterpup".
Luigi returns to his ghost-capturing days by reclaiming his Poltergust 5000 from Professor E. Gadd, who teleports him to various mansions haunted to the teeth with poltergeists and Boos.
