How to SWD
Super Wavedash, abbreviated as "SWD," is a very complicated maneuver and takes a lot of practice to pull off. In order to do this, drop a bomb, and as you're hitting the ground, immediately hit the opposite direction you want to go on the 41st frame, then hit the direction you want to go on the 42nd frame. This will result in Samus sliding across the level, as if in a wavedash, but she will go much farther.
