Gradual Infiltration

Gradual Infiltration is the bonus mission in the Gloomy Manor from Luigi's Mansion: Dark Moon. It is unlocked after Luigi clears the mansion's boss mission, and captures five Boos from previous missions.

Overview
Luigi has to capture all ghosts in a room in the shortest time he can. The order of the rooms and the amount and variety of ghosts are randomized every time Luigi does this mission. After clearing the sixth room, the mission is completed.

Objectives
Mission Goal: ''A group of ghosts have returned to the Gloomy Manor! Catch all of the ghosts as quickly as possible.''


 * Capture all the ghosts as soon as possible!
 * (rooms are randomized)

Description
''We have an...interesting situation. The Parascope is picking up mild paranormal signals in the manor. I'm sending you in to investigate.''

Messages
When clearing the Gloomy Manor of ghosts, what E. Gadd will say to Luigi at the end of the mission differs depending how quickly Luigi completes it:

"That'll do, Luigi! You weren't exactly quick about it, but you caught 'em all. Anyhoo, let's bring you back!" (Time over 4 minutes)

"Excellent, Luigi! You got all of 'em! That was really fast! The very definition of posthaste! Heh heh... Let's bring you back!" (Time under 4 minutes)

Trivia

 * This is the only mission where Luigi can collect all of the mansion's gems at once.
