Luigi's Mansion 2 HD is a puzzle-adventure game developed by Tantalus Media, released in 2024 for Nintendo Switch as a remaster of the original 3DS title Luigi's Mansion: Dark Moon. Players control Luigi across multiple distinct haunted mansions, completing a series of missions handed down by Professor E. Gadd. The primary tool is the Poltergust 5000, a vacuum device used to capture ghosts, though simply illuminating them is no longer sufficient to subdue them. Instead, players must first use a strobe function to stun ghosts before drawing them in. Each mansion features its own set of ghost types and environmental puzzle mechanics, requiring players to adapt their approach as they uncover hidden clues and keys to open new areas. The structure blends ghost-catching action with exploration and problem-solving, progressing through a mission-based format spread across varied supernatural settings.
