Nintendo always manages to roll out big surprises with the Nintendo Directs. The half-hour long sessions are always filled to the brim with brand new games for the company's active platforms, as well as big new announcements for projects coming down the pipeline. It's become a staple reaction to go into a Nintendo Direct with high anticipations and an open mind because you never know what you're going to get. That was basically the kind of thinking that gamers had going into this latest Nintendo Direct because they sure were hit with a big surprise. Nintendo announced that there is going to be a Luigi's Mansion 3 set to come out for the Nintendo Switch, and it's scheduled to release at some point in 2019. Release date details were sketchy, but gamers did get to see a little bit of gameplay on display.
The teaser trailer was only 37 seconds long, and posted on the Nintendo YouTube channel. It featured a brief look at the titular hero in action, exploring a brand new mansion filled to the brim with ghosts. The trailer starts with a duly frightened Luigi entering the mansion with his vacuum cleaner and flashlight, and then we proceed to see a series of clips where Luigi is exploring the mansion when ghosts pop out and scare the living daylights out of him. However, he's not entirely helpless. After a few jump-scares the green-clad plumber fights back by freezing the ghost with his light and then sucking them up with his ghost trapper. We see a few clips of Luigi's gadgets on display and a few more ghosts before the trailer rounds out.
The game is scheduled to release at some point in 2019 for the Nintendo Switch, and the current title is only a working title, so it may not be called Luigi's Mansion 3 upon release.
We do see that Luigi can utilize a few nifty tricks up his sleeve to waylay the ghosts, including firing off a plunger to distract the ghosts, or use the vacuum to suck them up. It appears as if there will be various traps littered throughout the house that Luigi will have to avoid, as well as puzzles he'll have to solve in order to progress further through the mansion. It looks like the level progression might be similar to other Super Mario games, where you have to complete certain tasks to unlock new areas, which is not too dissimilar from Super Mario 64.
There aren't many details available for Luigi's Mansion 3 and Nintendo has already said that it will be further detailing the game and its mechanics at another time. The game was announced right at the top of the Nintendo Direct, and later on Nintendo noted that as gamers wait it out they can play the new co-op mode for the Nintendo 3DS version of Luigi's Mansion.
This seems to be a tie-in with Luigi's cinematic segment in Super Smash Bros. Ultimate not too long ago where Nintendo introduced some of the Castlevania characters and stages. It hinted at Luigi returning for Luigi's Mansion, but in the cinematic, Luigi bit the dust after his soul was cleaved from his body. Nintendo did note that Luigi was "okay" after the deadly encounter.
I don't know if that has any bearing at all on the upcoming game or if it was just to build hype, but during the upcoming Nintendo Direct(s) I'm sure we'll find out more about the story behind Luigi's latest adventure for the Nintendo Switch.
