What each player can do here

P1 · Luigi
  • Luigi holds the Poltergust G-00 and the flashlight: stun ghosts with the Strobulb, then vacuum and slam them. The run only ends if Luigi runs out of health.
  • Luigi runs the cameras on the sets.
P2 · Gooigi
  • Gooigi walks over spikes and slips through bars and tight spaces that stop Luigi. Water and fire empty his health at once and send him back to Luigi.
  • Gooigi is the actor: whatever he does in front of a camera happens in the film.

If your skill levels differ: Losing health is never game over for Gooigi; the run only ends when Luigi runs out. So the newer player usually takes Gooigi and the steadier player takes Luigi. How to split the roles

On set

Part 1 of 3. Find the director's megaphone and help him film.

  1. BothThe director ghost holds the next button but will not work without his missing megaphone; explore the four sets to find it.
  2. BothOn each set, put Gooigi in front of the camera and have Luigi roll it; what Gooigi carries or does on camera carries over into the scene, which is how the set puzzles are solved.

The monster

Part 2 of 3. Beat the monster in the costume.

  1. BothThe boss is a ghost in a monster suit. Dodge its small fireballs and blow its big blue fireball back at it with the vacuum.
  2. BothThe next fireballs are green and too strong for one vacuum: Luigi and Gooigi must blow on them together. On the last one, mash the button.

Ghost cat

Part 3 of 3. Chase down the cat ghost for the button.

  1. BothA cat ghost runs off with the button. When it changes into its big form, turn your back so it creeps up behind you, then turn and flash it.
  2. BothPlain suction does not hurt it; slam it until it loses a tail. It flees and you repeat the trick in other rooms and on the floor below until all three tails are gone.

Where people tend to fall

  • Turn around too early and the cat goes back to its perch; wait until it is right behind you.

Boss

Morty (the monster in the suit)The film-set boss

  1. Blue fireball: Blow the large blue fireball back into its face.
  2. Green fireballs: Both players blow together to push the green fireball back; mash at the end.

PolterkittyThe ghost cat

  1. Each round: Turn away, flash when it rears up behind you, then slam it until a tail comes off. Three tails in all.

Achievements and extras

  • Six gems are hidden on this floor, and a Boo turns up here once you have the floor's elevator button and come back later.
