Super Smash Bros. for Nintendo 3DS and Wii U

Super Smash Bros. for Nintendo 3DS and Wii U (大乱闘スマッシュブラザーズ ニンテンドー スイッチ, Great Fray Smash Brothers for Nintendo 3DS / Wii U) is a Nintendo 3DS and Wii U game. It was developed by Namco Bandai Games Inc. and Sora, and was published by Nintendo. Both games are officially considered the fourth and fifth installments in the Super Smash Bros. series

Characters

 * Main article: Characters

Both games feature identical character rosters. The roster contains a total of 58 characters, 34 of which return from Super Smash Bros. Brawl, 3 of which return after being cut in the transition from Super Smash Bros. Melee to Super Smash Bros. Brawl (Dr. Mario, Mewtwo, and Roy), and 19 of which are new to the series (21 if all three Mii Fighters are considered separate characters), making it the game with the most playable characters.

It should be noted, however, that four unlockable characters (Ness, Jigglypuff, Ganondorf, and Bowser Jr.) in the Nintendo 3DS version are starter characters in the Wii U version. This was a personal choice of Masahiro Sakurai, who opted with his team to make said characters starters as they were unlockable in the Nintendo 3DS to save players who already had this version to take extra time to unlock all, but still have fun unlocking hidden content.

amiibo
amiibo are part of a new system introduced in Super Smash Bros. for Nintendo 3DS and Wii U, that uses near field communication (NFC) through special figurines of the respective characters, that can be bought separately. Through this, players bring the characters to the game as FPs (Figure Players), which can level up and be customized, learning more as they improve and interact with the Human Player, Computer Player, and other Figure Players. amiibo level up and learn faster by;
 * Having it play on someonelse's Nintendo 3DS and/or Wii U system.


 * Losing in Stock Battles.


 * Playing against different fighters


 * Making it fight against other amiibo


 * Use the same fighter as the amiibo you're playing against.

Stages
The two games feature considerably different stage selections, which is one of the primary differences between the two games. The two versions share 12 stages. The Nintendo 3DS version features more stages based on handheld console games, while the Wii U version features more stages based on home console games. Several stages in both games, however, ignore this distinction.

In addition to new stages, several Past Stages, known now as "Familiar Stages", reappear in both versions of the game. Three Familiar Stages are shared between the two games, and all are DLC.

Also, all stages can also be played as Omega Stages, which changes them into flat platforms similar to Final Destination.

The Nintendo 3DS version features a total of 42 stages with 7 unlockable stages and 8 DLC stages, 30 of which are new and 12 of which are familiar. The Wii U version features a total of 55 stages with 6 unlockable stages and 9 DLC stages, consisting of 34 new stages and 21 familiar ones.

New Items
*The Hocotate Bomb (similar to Olimar's Final Smash) and the POW Block (once a stage hazard) return as items.

Pokémon
In order to increase the rate of rare Pokémon appearing in battle, there are now two types of Poké Balls: the traditional red and white Poké Ball, which summons any Pokémon, and the Master Ball, which summons only rare and legendary Pokémon. However, Goldeen may still be summoned from a Master Ball (possibly a prank).

Modes
Much like previous installations, Super Smash Bros. for Nintendo 3DS and Wii U have different modes. However, some are exclusive to each version of the game. Unlike the previous game is there also no official story mode.

Smash Mode and 8-Player Smash
Also known as "VS Mode", it is the traditional 4-player battle that can be done with either Human players, CPUs, and Figure Players. Additionally, the Wii U version has the exclusive 8-Player Smash, which allow, as the name suggests, up to 8 players to play simultaneously, however the range of maps is smaller, meaning not all stages can be played with 8 players.

Nintendo 3DS version
In the new, modified version of Classic Mode, players choose different paths as they progress through a "World Map" to fight against waiting CPU opponents.

Other than battling the usual fighters in one-on-one fights, there is also the possibility of fighting giant or metal fighters, team battles with CPU players both aiding and against the player, and matches where the player must defeat opponents one after another or in groups.

Players are able to alter their "Fighter Balance": a system where gold is spent to adjust the intensity level. The higher the intensity, the smarter opponents will be, and the greater a player's rewards will be when victorious. Among those rewards are gold, trophies and items for character customization.

Before the player starts a level, a roller appears and determines the player's rewards. Rewards in red are for customization, green ones are trophies, and yellow means gold.

Wii U version
In the Wii U version, the trophy of the player's character is put in an arena along with other characters' trophies. The player can move their trophy around the arena, and if it touches a group of trophies, it will be tossed into a battle with those characters (a faint image of the stage will be under the base of the trophies). After the fight, all the defeated characters' trophies will be launched out of the arena, and the remaining trophies will organize in new groups.

Along with normal and 8-player matches, intruders may appear randomly before matches, being either metal or giants characters. In team battles, instead of a random CPU companion, a partner is chosen from the fighters defeated in previous battles. There is also a rival that can be challenged anytime; the longer they aren't battled, more powerful they will be, but it will also give more rewards when defeated.

The Fighter Balance and Reward Roller are kept from the Nintendo 3DS version.

This is also the first Smash Bros. game where Classic Mode allows two-player mode.

Stadium Mode
A mode comprised of the Multi-Man Smash, the new Target Blast and the Home-run Contest.

The score for these games effect the player's Global Smash Power, by either increasing or decreasing it, making each time count.

In Multi-Man Smash the player fights against all three types of Miis, with randomly generated appearances. Like in Super Smash Bros. Brawl, it offers a two-player mode.

Target Blast is played similarly to Home-Run Contest. However, players will be presented with a giant bomb instead of the Sandbag, and must inflict it enough damage to create the biggest explosion possible by racking up points from obstacles and targets waiting to be destroyed. Much like in Home-Run Contest, there is a 10-second timer, and after it expires the bomb will explode. Getting a good score depends on launching the bomb to areas rich with targets, getting the timing of the explosion just right, and using the explosive blocks found around the stage to maximum effect. It also allows two players together, however in form of a versus battle: each player get its turn to launch the bomb, rather than both players racking up damage against the bomb simultaneously. The player with the most points wins.

Home-Run Contest now features a strong barrier in the arena, allowing players to rack up damage for longer time. Like in Smash Bros. Brawl, it allows two-player mode.

For Fun and For Glory
Online gameplay has been completely reworked, where players can choose between two new modes:
 * For Fun: stage select is random (Final Destination is excluded from this), all items available, Smash battles only (free for all up to 4 players), and only wins are recorded.
 * For Glory: stage select is restricted to Omega Stages (Final Destination-type variant of existing stages), no items available, 1-1 battles possible, and both wins and losses are recorded. Additionally, players can freely customize those rules when playing with friends.

Smash Run
An mode exclusive to the Nintendo 3DS, where up to four players (3 other CPU players or 3 other Human players) can compete in two separate instances: one where they collect power-ups in a large maze-like stage, and another one where they fight each other in a normal stage, using the power-ups each character has picked up to their advantage.

Smash Tour
An exclusive game mode for the Wii U, where up to four players can play a board game. Players can collect characters and power ups for a final fight, but it is possible to lose them through traps and secondary fights. There are three board sizes, and also different options for how many turns you take.

Special Orders
Another exclusive mode to the Wii U, it consist in series of random challenges that give various rewards when completed; either custom parts, trophies or gold. The mode is presented by Master Hand and Crazy Hand, each with its unique way to play. To play Crazy Orders you either need to earn a ticket or pay a fee.

Master Orders
Every time you enter this mode, 3 random-created challenges of varying difficulty and entry fee (Gold) to play will be presented to the player; every challenge with different battle rules, special powers for fighters and even physics laws like altered gravity. Each challenge can only be tried once, winning allows you to get the secret reward, if you fail you get nothing. After playing a challenge, a new set of 3 will appear.

Crazy Orders
It costs 5000 gold or a free pass to play this mode (free passes are gained by playing various modes, such as Classic and Smash Tour). In Crazy Orders, you have a 10-minute time to complete various challenges, similar to the ones in Master Orders, and 3 are presented in each "round", with your damage percent carried over in each round. You can stop at any time during this, bringing you against a Stamina fight with Crazy Hand. The more rounds you played, more powerful Crazy Hand will be at the end and it can even be accompanied by CPU characters. You will only get your rewards after beating Crazy Hand, if at any time you lose a challenge or run out of time, Crazy Orders will end and you'll only receive a small portion of your reward stash.

Gameplay changes

 * Nintendo released a Nintendo GameCube Controller Adapter that allows to connect up to four original Nintendo GameCube controllers to play Super Smash Bros. for Wii U. The Nintendo GameCube controller was also released as a special edition, with a more aesthetic design.
 * Holding the Right Control Stick (C-Stick on the Nintendo GameCubecontroller) now charges Smash Attacks.
 * This is the first Super Smash Bros. game that allows up to 8 players simultaneously in Versus Mode. Additionally, other modes also have 5 or more characters in battle, in form of CPUs.
 * The A.I (Artificial Intelligence) of CPU characters have been greatly improved, especially the Level 9 CPUs; they often perfect shield, dodge and read attacks, and even try to gimp, and Meteor Smash its opponents.
 * The speed of the game is a balance between Super Smash Bros. Brawl and Super Smash Bros. Melee. This is to appeal to both casual and hardcore gamers after the lukewarm response by hardcore gamers to the former's more "floaty" mechanics.
 * The game in general is remarkable for being the first Smash game in the series to receive patch notes for character balance and bug fixes.
 * The game now favors both casual and hardcore players, with the introduction of For Glory and For Fun online modes, as a way to please different types of players.
 * Hitstun has been increased, allowing characters to pull true combos again, however not as effective as in Super Smash Bros. Melee. The new game mechanics now increases the amount of time characters have to act out of hitstun when being launched, which is identified by the trail of smoke they produce when receiving strong knockback. This means it is no longer possible to cancel hitstun with command input like it was possible in Brawl.
 * Directional Influence was originally different at the release of Super Smash Bros. for Nintendo 3DS, where it was required to input a vector directly to the knockback's vector. This was dubbed "vectoring". However, in the patch Version 1.0.4 of the Nintendo 3DS version, DI now functions like it was in the other games.
 * Additionally, the SDI (Smash Directional Influence, also known as "Hitstun Shuffling") has been nerfed. The SDI multiplier of multi-hit attacks was drastically reduced, meaning those attacks are now much more difficult to escape via SDI than they were in the previous games (so in a sense, all multi-hit attacks have been buffed).
 * Characters with consecutive standard attacks, such as Fox's infinite kick, can now input a finishing move to end the combo, dealing knockback. Little Mac was the first character seen performing this, in his official reveal trailer.
 * Characters with wall cling, such as Lucario and Sheik, can use it for a near infinite amount of time consecutively; however each time they jump out and cling again, the time they can stay on the wall is cut by half. This timer is reset once the character lands on ground.
 * All characters move faster when carrying heavy items such as crates or barrels, almost as fast as Donkey Kong (who still is the fastest character when carrying heavy items).
 * Meteor Smashes now causes opponents to ground-bounce characters if the player hits them in the air back to the stage, similar to using a Meteor Smash attack against ground opponents. Victims can prevent from being bounced by teching once they hit the ground.
 * Additionally, very few characters have attacks that always Meteor Smashes; many now have sourspots that still deal high knockback, but don't send opponents downwards. Notable characters affected by this are Samus, Ness and Ganondorf, known for having very reliable Down Air Attacks that always inflicted Meteor Smash no matter how they hit.
 * On the other hand, Meteor Cancelling is no longer possible, meaning that all Meteor Smashes are essentially spikes, increasing their effectiveness.
 * Projectile game has been balanced to improve match-ups.
 * Fast shooting projectiles have been nerfed to prevent spamming; in general they now have more startup and ending lag, meaning they will take more time to be fired and have more delay between shots. They also inflict less hitstun. Notable examples are Falco's Lasers and Pit's Arrows.
 * Slower and heavy hitting projectiles, on the other hand, have been buffed to increase their effectiveness compared to their fast counterparts; in general they now deal more damage and hitstun, as well increased knockback scaling, meaning they can KO sooner. Charging projectiles now charge slightly faster, with faster startup and less ending lag. Notable examples are Samus' Charge Shot and Lucario's Aura Sphere.
 * Additionally, some projectiles are limited to only one on stage at time, meaning the player can't spam them; they can only be used again if they naturally disappear or collides with a character, platform or another projectile. Notable examples include King Dedede's Gordos.
 * Reflectors and absorbers are more powerful now, with improved hitboxes. Ness and Lucas' PSI Magnet have been improved with special windboxes that absorbs projectiles close enough, meaning the projectile doesn't need to clash exactly with the psychic-field in order to be absorbed.
 * Random Tripping has been removed. Forced tripping, however, remains, since the banana peel item is still present, as well as the individual character attacks that can cause tripping.
 * Gliding has been removed. This means Charizard, Meta Knight and Pit no longer have an additional means of recovery.
 * Swimming is excluded from the Nintendo 3DS version, but exists in the Wii U version.
 * Some attacks with wind effect (pushboxes) have increased pushing power depending on the opponents' current percentage.
 * Much like Sakurai stated in one of his Miiverse posts, the difference of size between small and large characters is more noticeable than in Brawl; characters such as Bowser, Donkey Kong and King Dedede are remarkably larger than they were previously compared to other smaller characters such as Mario and Fox.
 * In addition, heavy characters received a boost in both offense and defense to compensate their lack of speed and larger size, by adding more knockback to most of their moves as well super armor for attacks and even normally; Bowser, for example, can shrug off some weaker attacks without flinching even when not attacking.
 * Character transformations mid-match have been completely removed from the game; Zero Suit Samus and Sheik are now separate characters from Samus and Zelda, respectively. Charizard is now also a stand-alone character, as opposed to previously being one of Pokemon Trainer's Pokémon.
 * Tether Recovery can now be done from an even longer range than before, and better sweetspots the ledge. In addition, multiple characters can latch on the ledge, but the one that actually grabs hold is determined by the same rules as the standard ledge grab.
 * Ledge mechanics have been reworked to improve the balance and meta-game:
 * To prevent the infamous edgehogging tactics and greatly expand the edge-game, a new ledge mechanic has been introduced, where a character will be automatically "kicked" off of the edge if another character tries to grab it. This doesn't cause damage, and makes edge-hogging KOs no longer possible. Air time and damage percentage of a specific character now affect how much time he/she will be invincible while holding the ledge.
 * Planking is no longer possible, meaning players can no longer release and grab the ledge repeatedly to gain invincibility frames; after releasing the ledge, the player can't re-grab for a couple of frames afterwards. Also, re-grabbing the ledge multiple times won't give invincibility frames; there is now a cooldown for ledge invincibility, which resets once the player set his foot on the stage.
 * With this, an advanced tactic called "trumping" has become quite popular among experienced players, where a player intentionally grabs the ledge as soon the opponent does in order to kick him/her off; since this animation leaves the opponent briefly vulnerable, it is possible to the player to grab the ledge and jump off as soon the opponent is kicked and proceed to counter attack. Other use of trumping is to grab the ledge to force the opponent to grab it again, and then proceed to use an attack that hits low, exploiting the fact that ledge invincibility is lost by re-grabbing the ledge before touching the stage.
 * Sweetspotting the ledge is slightly more difficult than in Super Smash Bros. Brawl, but not as much as in Melee; it is required the correct spacing in order to latch on, though. However, most Up Specials now have improved ledge-sweetspotting, preventing characters from falling when the recovery move pushes them below the platform slightly. However, it is still possible to grab the ledge backwards.
 * In addition, pretty much all stages now have adjusted collision to prevent characters going under the stage when using recovery moves; doing to so will conveniently push the character upwards so they can grab the ledge safely.
 * Characters no longer have two different types of ledge attacks depending on their percentage.
 * Stale-Move Negation has been slightly tweaked and no longer affects items (including character-generated items, such as Link and Toon Link's Bombs), however it now affects Grab Aerials.
 * A mechanic has been implemented, called "Rage", by fans. It increases the player's knockback dealt when his/her character is at high percentages, functioning similar to Lucario's Aura mechanic, but much less powerful (however only affects the knockback, not the damage). Characters start gaining this effect from 50%, with a knockback bonus capping when reaching 150%. This "Rage Mode" is made more visible after 100%, as characters begin emitting steam and flashing red.
 * The effect of flashing and steam is also visually announce to the opponents and the player himself that the character is at his/her limit.
 * As shown in the April's 7th Super Smash Bros. Direct, the characters' Special Moves can be customized to give certain results, such as Pit's arrows performing a spin after being fired, Kirby freezing characters instead of swallowing them, or Mario's Fireball being much larger but slower or smaller but faster.
 * During Play Nintendo - Super Smash Bros. Roundtable with Masahiro Sakurai, it has been further explained how that mechanic will function: each character have 2 variations of their original Special Attacks, totalizing 12 different Special Moves, 3 for each direction. However, to maintain the game's balance, these customizations will not be available for Online Mode "With Anyone", and can also be turned off in the game's options for other Modes.
 * A new ranking system has been introduced, called Global Smash Power. Differentiating from the traditional leaderboards seen in other games and seen by Sakurai as a more "fair" than the current leaderboard system seen in most online games.
 * Assist items (Assist Trophy, Pokeball, Master Ball) now only appear one at a time in the Nintendo 3DS version. In the Wii U version multiple can appear at a time.
 * When running out of a platform or edge, characters do a smooth "hopping" that is followed by the normal falling animation. Also, if the characters takes no action before landing on another platform, they will immediately continue running once they hit the ground instead of the standard landing animation.
 * Though originally there were plans to include a single player story mode, Sakurai has since changed his mind. There is no story mode in this installment of the game.
 * However, short movies featuring newcomer characters introductions, like the ones introducing Villager, Wii Fit Trainer, and Mega Man, take the place of the originally planned story mode cutscenes. These scenes, however, are not present on the Nintendo 3DS.
 * Star KOs and Screen KOs are now random, meaning that a character KO'd over the upper blast line won't always have be of these animations; both of these KOs now have the same animation length, with Screen KO being significantly longer than in previous games. Additionally, they no longer occur near the end of a timed match or Sudden Death; being instead replaced by regular Blast KOs.
 * Almost all stages now have a "Final Destination version", which is a flat version of the respective stage, without any platforms or stage hazards. This is referred to as the stage's "Omega" version.
 * In addition, players can set "Random Ω" in the options to automatically fight always in Omega Stages rather than manually selecting them.
 * It is also possible to set specific stages on or off as Omega versions.
 * Multi-Man Mode no longer pits players against clone characters like in previous games, it's now the Fighting Mii Team where the player fights randomly generated Miis of all three classes.
 * The Stage Builder in this game lets you build your own land using the Gamepad Style, with far more options than in Brawl, allowing much more fluid terrain as opposed of the "blocky" ones in Brawl. It also lets you make ledges grabable, create pass-through platforms, and draw hazardous areas. Other features include launching barrels similar to the Donkey Kong games, and moving platforms whose distance and trajectory can be set by the player. Background screens are now animated, and players are able to build much larger stages than in Brawl.

Aesthetic changes

 * Visually, the game is more stylized and "colorful" than Brawl, with colors being more saturated, as well sound effects being more discreet but yet cartoonish.
 * While in Brawl characters had a more realistic style and textures, in this game they are more distinct from each and favor details to make them look closer to their original incarnations and franchises. For example, while Mario and Kirby retain their more cartoonish styles, Link and Samus are more realistic, while still maintaining the brighter palette and effects.
 * Most visual effects received a similar treatment to make them stand out more:
 * Most regular attacks now have special graphical effects with high saturation and enhanced motion blur to give them a more "aggressive" feel, as if they are "cutting through air".
 * This was also added so players can see and identify attacks more easily, which holds true for the Nintendo 3DS version, where the screen is smaller.
 * The "impact-launch" effect has been altered to a colored light trail indicating which player will receive the point should a KO occur. Additionally, a red/black lightning effect will appear when a character is hit by a strong attack and/or has a high damage percentage, to indicate the character will likely be KO'd. This, of course, doesn't guarantee a KO, specially if DI is applied.
 * Whenever a character KOs another, his/her frame will flash with an aura with the player's port color, to indicate who dealt the finishing move. Additionally, the smoke trail of hit characters will now emit a colored glow which also matches the attacker's color.
 * Attacks based on Magic and PSI energy are no longer electric based, now producing a distinct spark and sound when they hit.
 * All characters are much more expressive now, with different animations on their faces even for specific attacks. Notable characters with high variety of expressions include King Dedede and Wario.
 * Some characters now display visual battle damage, a mechanic meant to be included in Brawl. Some of these include cracks on Meta Knight's mask and a bandage on Little Mac's face.
 * When a character is selected, one of his/her eyes will emit a small shine. The same will happen in match when characters with charging attacks (such as DK's Giant Punch and Samus' Charge Shot) to indicate they are at full charge.
 * Some animations have been adjusted to make various fighters face the screen more; characters in their idle pose no longer have their back turned to the screen. Additionally, the leg and arm positions of some characters are mirrored when facing left or right.
 * Damage percentage now starts changing colors earlier, going from yellow to red as damage rises. At around 30% to 50% the color is on shades of yellow, changing to orange around 60% to 80%, and finally becoming red over 90%. At percentages above 120%, the red becomes very dark. This applies to both versions.
 * When fast-falling, a small flash of light will blink next to the character's head to indicate that he/she is entering the fast-falling animation.
 * In Team Battle, it is now possible to choose any color for the characters, and their team affiliation will be marked by the respective color outlining them. This feature is available for both versions of the game.
 * Revival platforms now turn from yellow to red to warn the players how much time they have before their fighter falls.
 * Items have received more treatment in their textures to make them stand out more on the battlefield. Notable examples are the Home-Run Bat and the Beam Sword.
 * Certain items now have white triangle markers to make them stand out more, much like in the original Super Smash Bros.
 * Also, Assist Trophies and Pokémon from a Pokéball will also have a marker above them, in order to indicate which player activated them.
 * On the Victory Screen, after the character's fanfare finishes playing, a remix of the character selection screen theme from Super Smash Bros. will play.
 * Sound effects are now more distinct, with characters having more unique sounds associated with their franchises. Kirby's Inhale, for example, now has a sound more similar to its original sound from his games. This is specially noticeable for more "old school" characters such as Mega Man, Pac-Man and Ryu.
 * The "My Music" menu can also be accessed in the Stage Select screen.
 * Rankings and Records no longer display individual character statistics for player names, such as which character was mostly played by a specific player, or the amount of KOs players have.
 * It is no longer possible to tilt the screen while navigating through the menus using the Right Control Stick or C-Stick.
 * In the 3DS version, players highlight their characters by tapping on his/her character's icon at the bottom screen. This will set a marker on that character on the top screen, in order to more easily follow their movements.

Advanced Techniques
Some advanced techniques listed as "glitches" have been fixed in Patch 1.0.4. The advanced techniques are as it follows: The following techniques were avaliable at the launch of the Nintendo 3DS version, but were fixed in patch Version 1.0.4, and the release of the Wii U version removed them entirely.
 * Jump Cancel Throw: also possible in Brawl, this technique is still present in the 3DS/Wii U versions. Most notable when used with Mega Man and his Metal Blades.
 * Table Flipping: Mr. Game & Watch's Down tilt has pushboxes that when used at the right timing can deflect projectiles. Most notable when used against Pac-Man's Lazy Fruits. It can also be used against opponents recovering.
 * Perfect Pivoting: considered the "wavedash of 3DS/Wii U", it allows players to slide along the ground by canceling the dash through inputing the opposite direction.
 * Edge Pivot Dash: also known as "Edge Sliding", it consists in the character sliding while doing their Normal Atack or Down Smash Attack. This can be done in fall-through platforms and in the edges of the stage.
 * Reverse Aerial Rush: also known as TACing, this technique originated from Brawl, where players could attack with a Back Air Attack while running forward.
 * Turnaround Cancel: also known as TACing, it is performed during the turning animation of a dash, where it is possible to cancel it into a Forward Tilt, similar to the Reverse Aerial Rush technique, but on ground.
 * Roll Cancel: it consists of canceling the Forward Dodge Roll into a Dash Grab. It works most notably with Little Mac, who has the fastest roll in the game.
 * Instant Bomb Dropping: a technique performed by Link and Toon Link (though it works better with Link due his higher falling speed). By pressing the assigned button for Grabbing during a short hop, but before touching the ground, Link and Toon Link can drop their bombs in mid air and re-catch them while performing aerial attacks, without letting the bombs touch the ground.
 * Bomb Faking: a variation of the above technique, but performed by jumping backwards while dropping the bomb with the Grab Button and re-grab with Grab Aerial again, in order to trick rushing opponents.
 * The Wheo Catch: in this technique, instead of dropping the bomb in short-hops, Link and Toon Link perform a full double jump, and fast fall while throwing the bomb down, and re-grabbing before it touches the ground.
 * Dash Cancelled Up Smash: also known as DACUS, this technique originated from Brawl, where players could cancel their Dash Attack into an Up Smash.
 * Toss Canceling: it allows the characters Link, Toon Link and Peach to cancel their landing lag by tossing their special itens (Link and Toon Link's Bombs and Peach's Vegetables).
 * Wectoring: by using the vectoring mechanic, Wario had a bug that allowed players to change, redirect and manipulate his knockback, greatly improving his recovery.

Patch Updates
Patch Update is a feature added to both versions of the game, in order to fix in-game bugs and provide character balance.

Smash Bros. Fighter Ballot
During the Nintendo Direct held at April 1st, a new feature called Smash Bros. Fighter Ballot, was introduced to the official Smash Bros. site. It allowed fans to request character for Super Smash Bros. for Nintendo 3DS/Wii U through a small form. The deadline for requesting a character was October 3rd, 2015.
