Luigi checks into a hotel with Mario, Peach and Toad at the start of the game, but he soon discovers that his friends have been kidnapped.
King Boo, the main villain of the first two "Luigi's Mansion" games, has taken over the hotel and left it totally haunted.
Armed with the Poltergust G00, a ghost-sucking vacuum cleaner, Luigi has to get rid of the ghosts and find his friends.
The hotel in "Luigi's Mansion 3" is huge, so clearing out all the ghosts will be quite the task.
You'll use the Poltergust 5000 to weaken ghosts before catching them. Luigi can use it to pull objects around, too.
While "Luigi's Mansion 3" isn't a typical "Super Mario" game, there will still be a bit of platforming and exploration.
Luigi can also deploy a slimy clone of himself named Gooigi to slip between fences and avoid traps.
Gooigi can also help Luigi solve puzzles that require more than one set of hands.
"Luigi's Mansion 3" will also have a multiplayer mode for up to four people. Players work together to solve a series of challenges with a set time limit.
"Luigi's Mansion 3" doesn't have an official release date, but don't fret too much — it's due out before the end of 2019.
