Game Overview

Mario & Luigi RPG 3 is one of those weird, hilarious RPGs where you’re literally inside Bowser’s body—like, plumbing his guts, fighting bacteria as enemies, and even controlling his massive shell from the outside. The usual Mario RPG charm is here: timing-based attacks, goofy dialogue, and Luigi being… well, Luigi. But the twist this time? You’re juggling two perspectives—Mario and Luigi dodging white blood cells inside Bowser, while Bowser himself stomps around outside causing chaos. It’s as ridiculous as it sounds, and I mean that in the best way.

The combat’s still all about nailing those button presses for extra damage, but now you’ve got Bowser’s screen-clearing fire breath to play with too. And yeah, the puzzles get surprisingly creative when half the game takes place in an oversized turtle’s digestive system. Just don’t think too hard about the logistics.

If you liked the previous Mario & Luigi games, this one’s a no-brainer—it’s the same humor and tight gameplay, just with more bodily fluids.
