Mario & Luigi: Dream Team, known in Europe and Australia as Mario & Luigi: Dream Team Bros., is a role-playing video game developed by AlphaDream for the Nintendo 3DS. Revealed on Nintendo Direct on February 14, 2013, it is the fourth entry in the Mario & Luigi series of Mario role-playing games. The game was released in Europe on July 12, 2013, in Australia on July 13, 2013, in Japan on July 18, 2013, and in North America on August 11, 2013. In the United States, a download code for the game was included with a silver Mario & Luigi-themed Nintendo 3DS XL. The game was one of many Luigi-themed games released during Nintendo's "Year of Luigi" from March 2013 to March 2014, to celebrate the thirtieth anniversary since his original appearance in Mario Bros. in 1983. As a result, Luigi has a larger role in the game than he did in previous installments of the franchise.
