Check out those movie posters!
Luigi's Mansion 3 was shown off on the Treehouse at Nintendo's E3 2019 show. While demonstrating a "movie theater" level, a few movie posters on the wall showcase some familiar references to other games worked on by Next Level Games.
- Mario from the 2005 GameCube title, Super Mario Strikers
- Mario and co. from the 2007 Wii title, Mario Strikers Charged
- The boxer from the Bronx, Little Mac, from the 2009 Wii title, Punch-Out!!
- Luigi and King Boo from the 2013 3DS title, Luigi's Mansion: Dark Moon
And we couldn't figure out the one on the far back left. It looks like a wolf or some creature, potentially a boss later in the game? Or maybe it's related to the 2016 3DS title, Metroid Prime: Federation Force? Let us know what you think it could be!
