Being one of Luigi's most effective attacks it comes highly recommended. Luigi's smash uppercut (Up+A), for instance delivers a more powerful blow. The moves that Luigi does share with Mario are balanced differently. His third uppercut jump goes straight up, so if you're facing the wrong direction or too far off the ledge you'll fall into the oblivion.
This is due to the fact that he can jump higher than his brother and also tends to slip and slide a little more - so be careful around the edges.
When you first take hold of Luigi, you'll notice that controlling him just feels different than controlling Mario.
However, if you take enough time to explore his move list you'll quickly find he has several differences and a few tricks up his sleeve too. Gameplay Tips As one of the Super Mario Bros., one would assume Luigi to be a clone of his brother Mario.
