Hostile Intrusion

Hostile Intrusion is the bonus mission in the Haunted Towers of Luigi's Mansion: Dark Moon. It is unlocked after Luigi clears the mansion's boss mission, and captures five Boos from previous missions.

Messages
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)

Trivia

 * When Luigi enters the Laboratories, the normal mansion theme starts playing. If Luigi captures all ghosts in a room, the bonus mission music starts playing again. This is the only bonus mission where this occurs.
