"Special Move Combo's"
Something that my friend and Mr. Sakurai spoke about directly is a new mechanic added in to increase the strategy of play. Using certain combo's can have a character use different, much more powerful attacks that are not normally available. All characters have these attacks, though the mechanics are altered from character to character. 2 specific examples were given of these attacks, and all of these are used using combo's with standard moves:
Little Mac - Little Mac has a potent air Special Move Combo, which is accessed by using the following attacks in this order while in the air, it should be noted that for all of these, every attack must land for the special combo to activate, " Standard Neutral, Standard Up, Air Dodge, Standard Down" If this combo is successful, then rather than Little Mac's typical Standard Down, he will use a powerful meteor move, which will send the victim flying down, as well as propelling Little Mac up, potentially saving his life.
Mii Fighter (Gunner) - Mii Fighter Gunner has a powerful attack using these combo's, and it can be used by executing the following combo, "(The first 2 of these are in the air) Standard Combo, Standard Combo, (Lands on the stage) Down Tilt, Up Combo" Should this be executed correctly, then Mii Fighter would launch his/her opponent up, then let lose a devastating laser from their Plasma arm (This laser is described as a "Smaller, Vertical, Red version of Samus's Zero Laser" Sakurai noted that this attack is capable of KOing a Small character at 50%, a Medium Character at 70% and the Heaviest Character at 100%
