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

Mario & Luigi: Bowser's Inside Story + Bowser Jr.'s Journey (known as Mario & Luigi RPG3 DX in Japan) is a game for the Nintendo 3DS, released in Japan on December 27, 2018, and set to be released in America on January 11, 2019, in Europe on January 25, 2019, and in Australia on January 26, 2019. It was announced in a Nintendo Direct on March 8, 2018. The game is an enhanced remake of the 2009 Nintendo DS game Mario & Luigi: Bowser's Inside Story. The remake also features another story where Bowser Jr. takes action on an adventure, similar to Minion Quest: The Search for Bowser, with two important differences shown so far: a slot for an additional First Officer who will have its own actions just like Bowser Jr. as well as formations for the troops. The game is the second enhanced remake of the Mario & Luigi series, the fourth game in the series to be released for the Nintendo 3DS, and the seventh game in the series overall.

The game is now amiibo compatible: scanning one will grant the player an item. According to the manual, the same amiibo can only be scanned once per day.
