Nintendo has shed more light on the vague mention of multiplayer in Luigi's Mansion today. The multiplayer modes apparently focus on cooperative ghost-hunting in the "ScareScraper," a tower full of paranormal creatures.
"Hunter Mode" has each player take a different color Luigi, employing teamwork to hunt down ghosts in each floor before the timer runs out. Along the way you'll earn bonuses to help you catch ghosts even faster, and face off against a boss ghost at the top of every tower. You can attempt a tower consisting of 5, 10, or 25 floors, and it will feature adjustable difficulty levels.
The previous reveal only mentioned local multiplayer, but today's announcement confirms online multiplayer and Download Play as well. The game will be coming to 3DS on March 24.
