During Nintendo’s Super Smash Bros. Ultimate Direct last week, we saw Luigi kick the bucket, and now fans are speculating that it ties in to the game’s unannounced single-player campaign.
Luigi’s untimely death played out before our very eyes in the last week, but Nintendo has assured fans that the plumber is alive and well, despite his soul being cleaved from his body by the spectre of Castlevania’s Death. But Luigi’s apparent demise has led fans to believe the game’s unannounced single-player mode will see players rescue characters who have had their souls taken.
