Mario & Luigi: Bowser's Inside Story + Bowser Jr.'s Journey

About

Mario & Luigi: Bowser's Inside Story + Bowser Jr.'s Journey is a 2018 role-playing game developed by AlphaDream for the Nintendo 3DS, serving as an enhanced remake of the original Nintendo DS title. The core story follows Mario and Luigi, who become trapped inside Bowser's body and must navigate its interior while Bowser himself acts in the outside world, creating a dual-layered adventure that shifts between the brothers' microscopic exploits and Bowser's larger conflicts. Combat is turn-based and incorporates timed button inputs to improve attacks and dodge enemy moves. Alongside the main campaign, the remake introduces Bowser Jr.'s Journey, a separate side story in which Bowser's son assembles an army, arranges troops into battle formations, and deploys a variety of moves to support allies — adding a distinct strategic layer to the overall package.
