The Co-Op Experience
Luigi's Mansion 3 has two ways to play with friends:
Campaign Co-Op (2 players max) - the main story mode allows for two player drop-in/drop-out couch co-op. Once the player unlocks the ability the use "Gooigi," the second player can grab a Joy-Con and play as Luigi's gooey doppleganger. They have access to all the same abilities as Luigi, and can traverse certain areas the Luigi is not able to cross (such as spike traps).
ScareScraper Mode (8 players max) - the ScareScraper Mode supports a maximum of 4 Switches - connected either via local wireless or online - each with their own copy of Luigi's Mansion 3. On each Switch, two players can work together with one player controlling Luigi and the other controlling Gooigi. The total player count, then, is 8; 4 Switches, 2 players per Switch. In this mode, players must work together complete a variety of objectives across a set number of procedurally generated floors within the time allotted.
