A down attack in Super Smash Flash, called special attack within the How to Play section (not to be confused with an actual special attack), is an attack that is performed by pressing the attack button with putting the down key. The down attack is more or less an equivalent to the down special move found in the official Super Smash Bros. games as attacks within this range include close-ranged attacks that surround the character's frame, like Cloud's Materia orbs, or launching attacks that directly make the character travel a far fixed distance, the most out of all the other attacks, like Sonic's Spin Dash. Unlike the other attacks in the game, some down attacks cannot be held indefinitely with the attack button and attempting to do so will make the character to perform his/her/its standard attack instead afterwards. However, by finding and carry an item makes it still possible to hold these attacks indefinitely, as this is the only way that will allow to do it.
