Just as any bonus mission in the game, Luigi has to capture ghosts in the shortest time he can. The order of the rooms and the variety and quantity of ghosts vary each time Luigi plays this mission. The mission is complete when Luigi clears the sixth room.
We have a small problem. The Parascope found significant paranormal signs in the towers. Nothing you can't manage!
When clearing the Haunted Towers of ghosts, what E. Gadd says to Luigi at the end of the mission differs depending how quickly Luigi completes it:
"That's the last of 'em, Luigi! Hopefully you did it fast enough so we don't get another event like this anytime soon. Come on back now." (Time over 4:30)
"Atta boy, Luigi! That's the last of 'em. You really caught those ghosts quick! The Parascope could hardly keep up! You ready to come on back? Hold on." (Time under 4:30)
