Super Attack

An Advanced Command is an upgraded Bros. Attack in Mario & Luigi: Superstar Saga. Advanced Commands are different from the regular Bros. Attacks. They can change the effects of the attack. To unlock an Advanced Command for each Bros. Attack, Mario or Luigi must successfully execute a said move a number of times, as shown below:

Mario's Advanced Commands
