As the lean, green second string, Luigi has rarely been one to take the lead. But it's time for Luigi to get out of Mario's shadow — and head into the shadows and winding halls of some very spooky mansions. With the help of his trusty Poltergust 5000 ghost-sucking vacuum cleaner, the nervous and reluctant Luigi will have to face his fears to remove the stubborn specters from the mansions and collect some treasure along the way.
