Gameplay Changes


 * The general launch rate has been slightly decreased.
 * The Rage mechanic has been removed.
 * The Balloon Knockback mechanic has been removed.
 * The 1-1 damage mechanic has been removed.
 * Tethers can now be angled.
 * Pummels are faster, and it is easier to perform one or two pummels than a throw without the opponent escaping from the grab.
 * All fighters that can crawl can also pseudo-crawl.
 * There is a brand new mechanic called Edgeshifting. By pressing the Shield button when you are on a ledge, you can perform a directional air dodge off of the ledge.
 * There is another brand new mechanic called Dropping. By pressing the Y button when on the ground, the fighter will fall face-first onto the ground, without taking any damage. This allows for your fighter to perform their wake-up attack at any point without needing to get hit first. When you press Y in the air, it is simply another button for air dodging.

Mode Specific

 * In addition to Random Stage Switch (which is no longer unlockable) there is also Random Fighter Switch.
 * Sudden Death now has two variants, one being the variant from Ultimate, the other being the variant from previous games, the only difference being in the latter, damage is 999% instead of 300%. You can select which variant will appear in Rules.
 * Special Smash is removed. All options that were available in Special Smash can be found in Regular Smash under Rules.
 * In Options, you can choose whether Fighter Selection or Stage Selection comes first.
 * The option to turn off stage hazards has been removed.

Other

 * The amount of stages is the same as the amount of fighters. Every fighter has a corresponding stage. The only expections are Battlefield and Final Destination, which stand on their own.
 * All characters now have 16 different costumes as opposed to 8.
