Super Smash Bros. Ultimate

Super Smash Bros. Ultimate is a game in the Super Smash Bros. series for the Nintendo Switch. The game was announced through a teaser trailer in the March 2018 Nintendo Direct, and was released on December 7, 2018. The game features 103 base stages and 74 base playable characters (with six more characters and five more stages as downloadable content), making it the largest Super Smash Bros. game in terms of content in the series.

Super Smash Bros. Ultimate was made available for pre-order and pre-loading from the Nintendo eShop beginning November 1, 2018. The game takes up approximately 14.3 GB of the Nintendo Switch's memory.

Gameplay
Super Smash Bros. Ultimate retains the series' basic gameplay elements, with several new mechanics and changes. As with previous installments, the objective of the game is to launch opponents off the stage. Players build each other's damage percentage through attacks, and the higher the percentage, the farther they fly when they are hit. This time, the damage display is in decimal notation, adding a tenth to the number. Additionally, when an opponent is launched, their launch speed is the fastest at the start, unlike in previous games in the series. During 1-on-1 battles, all fighters' attacks deal 1.2x their regular damage, which is done to "increase gameplay speed." Additionally, characters can use any ground attack out of a run (e.g. standard attacks, tilt attacks, smash attacks), while any aerial attack can be used while climbing a ladder, officially known as a "ladder attack".

Three techniques are also introduced in Super Smash Bros. Ultimate: the Directional Air Dodge, Short-Hop Attack, and a new version of the Perfect Shield. The Directional Air Dodge, a technique carried over from Super Smash Bros. Melee, allows the player to dodge while moving at the direction they tilt, which can also be used for recovery. However, if a player dodges excessively—whether in the air or on the ground—they become more vulnerable to attacks, with less intangibility and lower dodge speed. The Short-Hop Attack is performed by pressing the attack and jump buttons at the same time, allowing the player to hop a short distance off the ground while performing an air attack; however, all short-hopped aerial attacks deal 0.85x their regular damage (excluding special moves, and certain states such as Peach and Daisy's Floating Jump attacks and the Super Leaf item). The Perfect Shield can be used to block attacks without depleting the user's shield. However, unlike in past installments, where it is activated by pressing the shield button before an attack connects, the Perfect Shield is instead performed by releasing the shield button just as an opponent's attack lands, nullifying the attack.

During a match, the fighter that is in the lead occasionally emits a glimmer of light. If a match enters Sudden Death, unlike in previous games where Bob-ombs begin to drop after a period of time, the screen slowly zooms in on the center of the stage, shrinking the field of view and stage boundary and thereby making it easier for fighters to be KO'd. The Sudden Death mode is visually accompanied by flames that intensify as the screen zooms in on the stage. Bob-ombs still drop on the stage if enough time passes and no one is KO'd.

As with Super Smash Bros. for Wii U, Super Smash Bros. Ultimate also supports Nintendo GameCube controllers.

Super Smash Bros. Ultimate is available in 11 different languages: Japanese, English, French, Spanish, German, Italian, Dutch, Russian, Simplified Chinese, Traditional Chinese, and Korean, all of which are fully voiced. However the Chinese versions use the Japanese voice set, and some of the specific names (characters, stages, items etc.) are also not translated and use their English names instead, probably due to copyright reasons (mostly for third-party games) or they were not intended to have official Chinese versions for the original games. The player can also change the dialect for the English, French, and Spanish languages by changing the "Region" setting in the System Settings for the console (though in the case of English, it only changes the names for certain characters, stages etc., such as Duck Hunt being called "Duck Hunt Duo" and the Find Mii stage into "StreetPass Quest").

Smash
Before starting a match, the player can create their own preset rules, such as the number of stocks and time limit, which they can quickly select at any time. In addition to Time and Stock modes, Stamina mode is now a standard mode alongside the aforementioned two, and no longer a part of Special Smash. Stocks can also be added to Stamina mode - and it can now be played online.

8-Player Smash also returns from Super Smash Bros. for Wii U, and can now be played on any stage from the start.

A new rule option added to Super Smash Bros. Ultimate is the Final Smash Meter, which appears below each fighter's damage meter and fills up as the player takes damage from opponent attacks, similar to Little Mac's Power Meter. Once it is full, the player can then use a Final Smash. These Final Smashes deal less damage and knockback than regular Final Smashes obtained from Smash Balls, and like them, only one can be used at a time.

Squad Strike
Squad Strike (Japanese: 団体戦 Dantaisen, Team Competition) is an elimination-style battle mode added to Super Smash Bros. Ultimate. The player can choose between 3-on-3 or 5-on-5 Squad Strikes, which can be carried out with one player on each side playing as three or five characters, or three or five players on each side each playing as one character. In a Squad Strike, both sides battle each other as the three or five characters consecutively in one battle. Characters can only be picked once per team, including amiibo fighters.

Tourney
Tourney returns from Super Smash Bros. Brawl, allowing up to 32 participants to compete. After selecting the number of total participants, number of CPU players and tourney type, the game automatically generates a tournament bracket. This mode is also compatible with amiibo fighters.

Special Smash
In a new Special Smash mode, Smashdown (Japanese: 全員バトル Zen'in Batoru, All-Members Battle), players enter a series of matches selecting a character for each one. After one match ends, however, the characters used in that match are no longer available for subsequent matches, forcing players to select a different character for the next one. Smashdown is the only mode which supports 8-Player Smash.

Classic
Classic mode returns from previous installments, returning to its original format last seen in Super Smash Bros. Brawl, in which the player fights multiple opponents in a linear series of matches to reach the end. This time, each fighter has a set series of opponents to face. Unlike Classic Mode's previous incarnations, the player is always given one stock, never being able to adjust the stock number before initiating the mode. When the player is KO'd, using a continue no longer causes the current match they are in to restart; instead, the match begins right where it left off, but the player starts with 0%. At the end of each path, the fighter has a specific boss they are required to fight.

Adventure
The Adventure mode in this game is called World of Light. It has a board game-like map, and elements and maps based off of various games have been shown; Warp Pipes and ! Switches are noticeable. Unlike the Subspace Emissary, which is very plot-heavy, World of Light is used to demonstrate the functionalities of spirits and spirit battles, and has a very loose plot to leave the player free to explore the light and dark realms of the Adventure mode. World of Light also has considerably fewer cutscenes than the Subspace Emissary, though most of them are silent, akin to Subspace Emissary's cutscenes; the lone exception being the introductory scene.

During the events of the Adventure mode, a monster called Galeem defeats all of the fighters except Kirby, imprisoning them in the eponymous World of Light, where they are cloned and their clones are possessed by spirits, which are the other victims of Galeem's attack. Once Kirby has freed Mario and more fighters and spirits in the Light Realm and defeated Galeem, a new monster named Dharkon appears, opening a path to the Dark Realm, forcing Galeem to retreat. When the remaining fighters and spirits are freed in the Dark Realm (as well as defeating Dharkon), Galeem appears to confront Dharkon, putting the player in a third realm: a mixture of the Light and Dark Realms.

Three endings exist in the Adventure Mode: two bad endings with Galeem or Dharkon respectively, and a true ending with both bosses. The first ending is achieved by defeating too many dark puppet fighters, thus forcing the player to fight Galeem; when Galeem is defeated, Dharkon destroys Galeem and his army, encroaching the universe in darkness. The second ending is achieved by defeating too many light puppet fighters, thus forcing the player to fight Dharkon; when Dharkon is defeated, Galeem unleashes another wave of light, essentially engulfing the universe in light again. The third ending is achieved by defeating an equal number of light and dark puppet fighters, making the player fight both Galeem and Dharkon simultaneously; when the player wins, the universe is restored to its original state, while all spirits fly back to their original worlds.

Training
Training mode lets players practice and experiment with characters' moves, items and the CPU as well as manipulate gameplay elements (such as game speed and damage), also returning from previous installments. The mode now features an exclusive numbered, grid-like stage, which allows the player to measure distances such as jump height and projectile range. In addition, it is now possible to toggle whether or not to show the trajectory at which the CPU would be launched from an attack at 50% damage in the form of a green curve, alongside the trajectory if they would be launched at 0% damage (a red curve) and 100% damage (a blue curve). Unlike Super Smash Bros. for Nintendo 3DS / Wii U, this mode is also compatible with amiibo fighters.

Playable characters
In addition to introducing new characters, Super Smash Bros. Ultimate features every previously playable character in the series. Counting Pokémon Trainer and his/her Pokémon as a single fighter and the three Mii Fighter types separately, a total of 74 fighters, including 7 Echo Fighters (certain characters, mainly newcomers, whose movesets are heavily derived from those of other characters, and are represented by an epsilon symbol "ε"), are playable in the Super Smash Bros. Ultimate base game. It has also been confirmed that 6 fighters will be released after launch as DLC. The number beside each playable character (excluding Echo Fighters) signifies the order in which they were announced to be playable in the Super Smash Bros. series; in the case of the unlockable characters from Super Smash Bros. Melee, their order is based on the number of Vs. matches required to unlock them in that game. The starting roster consists of the eight starting fighters from the original Super Smash Bros., as well as the ability to create a Mii to include them as starter characters; the rest of the roster needs to be unlocked.

Newcomers
Super Smash Bros. Ultimate features eleven base newcomers (five being Echo Fighters) and six downloadable characters. Five out of the six DLC characters can be purchased via the Fighters Pass or individually upon release. Piranha Plant, who was made available for free to players who redeemed Gold Points from the game and was made available for purchase on a later date, is not included in the Fighters Pass. Characters marked with an asterisk (*) are downloadable content.

 * Galeem
 * Dharkon

Stages
Unlike in previous installments, stages are selected before characters in Super Smash Bros. Ultimate. All stages can not only be played in their Final Destination form (known as Omega (Ω) form) as in Super Smash Bros. for Nintendo 3DS / Wii U, but also in a new Battlefield form, which adds three floating, pass-through platforms. Like the original Final Destination and Battlefield, in both forms for all stages, the stage is set on a large platform floating over an abyss, as opposed to a large pillar with walls leading down to the bottom as is the case with several Omega stages in the previous installments. The player is also given the option to turn off stage hazards.

A new feature added to Super Smash Bros. Ultimate is Stage Morph, which causes the stage on which players are currently fighting to transform into another stage in the middle of the match. The player can choose two stages for this function, and can also set the frequency at which they transform between each other.

There are 103 stages in the base game, all of which are available from the start. There are also five additional stages planned to be released as DLC. The following list is sorted by the original Super Smash Bros. games in which they first appear. Stages marked with an asterisk (*) are downloadable content.

Nintendo Labo VR
After downloading the version 3.1.0 update released on May 30, 2019, the Nintendo Labo's Toy-Con VR Goggles can be used in the "VR" mode (found in "Games & More"), which allows a single player to play regular matches against CPUs or spectate CPU-controlled matches in virtual reality. VR mode does not include the same rules and stages as Smash mode, as only Time matches of up to 10 minutes can be played, and only the CPU levels, launch rates, score/damage displays, and stage selection mode can be modified. Items also cannot be used.

The following 50 stages are available in VR:

The console features a design of the original eight Super Smash Bros. series characters on the front of the dock, as well as the Super Smash Bros. symbol printed across the Joy-Con. A Super Smash Bros. Ultimate-edition Nintendo GameCube Controller and the GameCube Controller Adapter previously released for Super Smash Bros. for Wii U also released on the same day.

Critical
Super Smash Bros. Ultimate has received widespread critical acclaim.

Sales
As of January 31, 2019, Super Smash Bros. Ultimate has sold 12.08 million units worldwide, making it the third best-selling first-party game on the Nintendo Switch.

Stages

 * Final Destination in the E3 demo was simply the Omega version of Battlefield, as the final design was not revealed at the time.

Character select screen and alternate costumes

 * Ridley has two alternate costumes based off of Meta Ridley, but they were not present in the demo, instead featuring black and white recolored Ridleys as placeholders.
 * In the demo, Villager's seventh and eighth alternate palette swaps had light skin like in the previous game, while in the final game, they have dark skin. Similarly, the Pokémon Trainer's seventh palette swap had light skin, but was changed to dark skin in the final game.
 * In the E3 demo, Sonic's fourth alternate costume used a pale blue shade of fur rather than white fur like in the previous game. This has since been fixed.
 * In the E3 demo of the game, Mario, Pikachu, Villager, and Link's portraits used their in-game models as opposed to the renders made for them in the game. This has since been fixed.
 * However, Link's hat in the Tunic of the Wild costume was pointed toward the top right, while in his official render, it goes behind his head and is pointed to the left.
 * In the demo, the Ice Climbers on the character select screen always showed Popo in the front. The final game would show Nana in the front for the 5th-8th alternate costumes.
 * Wario's buttons on his overalls in the E3 video were gold, as opposed to their usual white. However, in his default overalls artwork, they are white.
 * A pre-release image of Luigi in his Waluigi inspired costume has the "L" colored green. In the final game, it is colored purple, just like in Super Smash Bros. for Nintendo 3DS and Super Smash Bros. for Wii U.

Victory themes

 * Mario's victory theme used the full theme as with the previous games in the demo. In the final game, it is slightly abridged in the end.
 * Fire Emblem victory themes used the same tempo as the previous games in the demo. In the final game, it is sped up.
 * The Legend of Zelda characters, Pokémon characters and the Ice Climbers used their respective victory theme originating from Super Smash Bros. Brawl. In the final game, they each receive new victory themes which are shorter versions of the originals (the Legend of Zelda characters' uses a new arrangement altogether).
 * Ness used his standard victory theme from Super Smash Bros. Brawl and Super Smash Bros. for Nintendo 3DS / Wii U, while in the final game, he and Lucas receive a new one based off of the final two of the Eight Melodies from EarthBound.
 * In the demo, Corrin used the normal Fire Emblem victory theme with Marth and Ike, while in the final game, they have a unique victory theme, based off of "Lost in Thoughts All Alone" from Fire Emblem Fates.
 * Ridley's victory theme sounds different in the demo compared to the final game.

Gameplay

 * In Rosalina's character showcase video, her Final Smash Power Star took on the appearance of a Power Star just like in the previous game. However, in the actual game, the Final Smash now uses a Grand Star.
 * In Pikachu's character showcase video, Mr. Game & Watch could be seen in normal form when using his forward smash based off of Fire Attack. In the final game, he takes on the appearance of the characters from Fire Attack just like many of his other moves.
 * This had the unintended side effect of attracting criticism for its portrayal of a Native American stereotype (itself sourced from the original version of Fire Attack). Nintendo of America responded to the criticism by removing the feather via an update patch, similar to a previous change in its re-release in Game & Watch Gallery 4.
 * During Olimar's character showcase video, his Final Smash End of Day did not show visible Bulborbs even though the chomping sound effects and visuals could be heard and seen. This was fixed in the final game.
 * In the E3 demo, Ike did not speak during his victory poses.
 * In Roy's character showcase video, he is seen with a new dashing animation, but in the final build of the game, he reuses his old dashing animation from the previous game.
 * During Luigi's character showcase trailer, Dr. Mario's Super Sheet uses Mario's Cape animation, rather than the new animation specific to Dr. Mario.
 * When King K. Rool used his Final Smash Blast-O-Matic in the early builds of the game, the target(s) would take damage before the laser actually hit Donkey Kong Island. This was later fixed.
 * King K. Rool's Super Smash Blog entry on the official website refers to his down special move as "Stomach Attack." This would be changed to Gut Check in the final game.
 * In the E3 trailer, King Dedede's eyes are wide open when he crouches. In the final game, they are partially closed.

Other

 * On the Super Smash Bros. Ultimate Direct on August 8, 2018, the description of the Smash mode was "Battle with up to 8 players in regular battle!" In the final version of the game, it instead says, "Battle up to eight fighters." The image for Smash mode was also different, with Mario, Link, Samus and Bowser. The final version has Kirby, Bowser, Mario and Pit.
