Mario & Luigi: Solid Gold is an RPG game released for the Nintendo Switch in 2025. It is the eighth instalment in the Mario & Luigi series and the sixth original game in the series. It is the first to be developed by Good-Feel and Sandstorm Interactive, who both took over after AlphaDream went defunct in 2019. The game's plot revolves around Mario and Luigi working together with inanimate sculptures of themselves made of gold and silver respectively in order to face off against Midbus and the Shroobs, who have broken out of Bowser's freezer.

==Story==
==Gameplay==
The gameplay of Mario & Luigi: Solid Gold stays functionally similar to previous titles in the series, more so taking inspiration from the previous game Mario & Luigi: Paper Jam. Maintaining traditional features in the series, such as the enemy attack avoiding/counter attack techniques in battles and the usage of different maneuvers to solve puzzles in the overworld. With the addition of Gold Mario and Silver Luigi, players control Mario (A), Luigi (B), Gold Mario (X) and Silver Luigi (Y) in a square, with both sets of brothers walking side by side. In terms of techniques, both sets of brothers posses their own actions, which can be combined when solving certain puzzles in the overworld, similar to Mario & Luigi: Partners in Time. 
=== Battle System ===
When starting a fight, one of the brothers must touch an enemy or perform a first strike by jumping on the enemy's head or hitting it on the head with a hammer. In battle, players control all four characters in the field as them and the enemies take turns attacking each other. Similar to Paper Mario in Mario & Luigi: Paper Jam, Gold Mario and Silver Luigi fight alongside Mario and Luigi in the field, standing apart each other behind them, with all four characters forming a circle in the field. Ability wise, Gold Mario and Silver Luigi aren't too different from Mario and Luigi when it comes to dodging enemies and attacking them, however notable but minor differences between both sets of brothers include Gold Mario and Silver Luigi having higher POW stats and being able to cause small coin explosions when performing attacks, with coins from the explosions landing on the enemies. 
Bros. Attacks use all four of the characters when they are in the field together. In certain parts of the game when the two sets of brothers are separated from each other, they don't need a specific number of brothers to be used, however all four brothers would normally be needed to make the attacks very powerful, or to use special commands that deal more damage when using the attacks.
Battle Cards from Mario & Luigi: Paper Jam return and they apply to the newest feature to the battle system. The Coin Meter. Every time one of the brothers performs their attack, whatever rating they get from performing it will add an amount of coins to a meter displayed on the top lefthand corner of the screen, the number of coins added range from 100 to 500, OK giving 100, Good giving 200, Great giving 300, Excellent giving 400 and Amazing giving 500. The coins added to the meter can be used to buy a Battle Card in the fight. Battle Cards themselves cost 10,000 to 80,000 coins to buy in a fight and when the player buys a card, the card's effect is initiated, which affects the fight in certain ways, such as increasing the brothers' HP and other stats or damaging the enemies in the field. 
Levelling Up works like it did in the first four games, where the player can add an additional number to one of the six stats the brothers' have. After reaching a rank when levelling up, 2,000 coins are added to the Coin Meter.

== Items ==
== Bros. Attacks ==
Bros. Attacks are special methods of attacking enemies in battle. They use special items in order to help the four brothers damage the enemies. When the four brothers are together in the field, all of them work together in performing these attacks, however when they are split up in their respective pairs in different parts of the game's story, they still perform these attacks despite the lack of input from the other pair. Bros. Attacks are unlocked in the overworld when the brothers find a Red Block with the letter B on it.
