|Fire a LOOUUUD sonic wave. Catch it to get a LOOUUDEER wave.|
The Noise Crush is a sound wave that travels horizontally, with the ability to deal damage to enemies that are hit. An uncharged Noise Crush can bounce off walls, and if it is touched by the player, the projectile is despawned to allow the player to charge it and drop a stronger sound wave that passes through walls. The charging does not need to keep any button pressed, and shooting the stronger Noise Crush needs the player to press fire. Shooting the charged Noise Crush does not waste any weapon energy. If the uncharged projectile does not despawn by its eighth bounce off a wall, it will lose collision with tilesets and level objects and travel off-screen.
The Noise Crush will despawn if it travels off screen. If a uncharged Noise Crush defeats an enemy, the projectile will despawn, but if a charged Noise Crush defeats an enemy, it will not despawn. In the source material, the large Noise Crush was despawned upon contact of enemies.
- The player's Noise Crush projectile is coloured purple, while Shade Man's Noise Crush projectile is coloured green. In Mega Man: The Power Battle, the player's Noise Crush is green.
- Much like in Mega Man 7, if the player quickly moves into their Noise Crush projectile right after firing it, they can quickly power up the weapon, without waiting for the Noise Crush projectile to bounce off a wall and return to the player. This is especially useful in instances where there are no walls to bounce the projectile off of.
