Editing Adventure Mode: The Subspace Emissary

|image=[[File:Subspace Emissary Logo.jpg|250px]]

'''Adventure Mode: The Subspace Emissary''' ({{ja|亜空の使者|Akū no Shisha}}, ''Emissary of Subspace''), sometimes abbreviated as '''SSE''' or shortened to '''Subspace Emissary''', is a mode in ''[[Super Smash Bros. Brawl]]'' and the successor to ''[[Melee]]''{{'}}s [[Adventure Mode]]. It was hinted at with the [http://www.smashbros.com/wii/en_us/gamemode/modea/modea01.html This world...] [[DOJO|Dojo]] update on July 20th, 2007, and fully unveiled on August 3rd of the same year. This mode was succeeded by ''[[Super Smash Bros. Ultimate]]''{{'}}s. [[World of Light]].

On July 20th, [[Smash Bros. DOJO!!]] was updated with a collection of enigmatic images that depicted {{SSBB|Mario}} and {{SSBB|Kirby}} transforming from [[Trophy|trophies]] into fighters (akin to the introduction of ''Melee''). After Kirby's apparent defeat at the hands of Mario, he is changed back into a trophy, but Mario reverses the transformation and Mario and Kirby shake hands. However, the sky darkens soon after, and [[Meta Knight]]’s ship, the [[Halberd]], flies over the stadium, soon followed by the appearance of [[Primid|a mysterious character]]. The screenshots were accompanied by this description:

The post was placed under a mode referred to as "???" until August 3rd when it was changed to "Adventure Mode". On August 3rd, Smash Bros. DOJO!! was updated again. This time, more information was given. The mode was dubbed "The Subspace Emissary", and a multitude of screenshots were shown, as well as a cutscene related to the "This World…" update. In the cutscene, Mario and Kirby were seen shaking hands, as depicted in the screenshots, and after waving to the crowd, the Halberd appeared as it did in "This World…". The mysterious character from before was shown to be one of apparently many odd, robot-like creatures formed from some sort of shadowy matter. {{SSBB|Peach}} and {{SSBB|Zelda}} were seen watching from the sidelines but rushed down to the middle of the stadium to assist Mario and Kirby in fighting the mysterious army. After Peach and Zelda reach the stage and help destroy the [[Primid]]s, an entity from the sky called the [[Ancient Minister]] appears on the stage. The Ancient Minister drops a [[Subspace Bomb]] on the arena, then flies off. As Mario approaches the bomb, he is hit by a cannonball and is sent flying from the arena. [[Petey Piranha]] appears and captures Peach and Zelda in cages.  

The various screenshots in the update depicted a multitude of new enemies, as well as a few familiar ones, such as a [[Hammer Bro]], who was previously confirmed as an [[Assist Trophy]], and {{b|Bullet Bill|enemy}}s. There were also a new series of enemies that were introduced that are part of the Subspace army. Some enemies of the Subspace army appear to be helpful while other ones are dangerous.

Masahiro Sakurai has stated that substantial single-player content was a core priority during the development of ''Brawl''. An adventure on the scale of a stand alone video game was decided early in development. Shigeru Miyamoto has stated that Sakurai always wanted to make a mode like this for the series, but was advised to focus on the multiplayer aspects of previous games due to the relatively short development times of previous games and there already being no shortage of single-player games. The much longer development time allotted to ''Brawl'' allowed the mode to be made.<ref>[https://www.eurogamer.net/i-miyamotosakurai?page=2 Miyamoto and Sakurai on Nintendo Wii

E3: Smash Bros., Mario, more.]</ref> The initial plan was to outsource development of this mode to another studio, but no suitable contractor was available. In the end, the entire mode was developed internally by the main ''Brawl'' team. Only the cutscenes were created by a different studio.<ref>[https://www.youtube.com/watch?v=dXpFTHtlmCo&t Super Smash Bros. Brawl [Game Concepts]]</ref>

The Subspace Emissary mode is a side-scrolling adventure in the style of a platformer, inspired by the {{uv|Mario}} and {{uv|Kirby}} games. However, it retains all basic mechanics of the [[Super Smash Bros. (series)|''Super Smash Bros.'' series]], such as a [[damage meter]], [[stock]]s, and Smash-style attacks. It can also be classified as a beat 'em up; often stages will [[ambush|pause at specific points]] and force the player to defeat a set of enemies, which prevents one from simply running through everything.

The mode features a [[Adventure Map|world map]] where stages are selected; once a stage is selected, the difficulty can be chosen, and the character(s) will enter the stage. The selectable characters will change depending on the plot. Stages that have been completed already can be played again, with the one exception being a stage being consumed by a Subspace Bomb; if this happens, the player must complete the Subspace Emissary to be able to access the stage again.

The mode also has a two-player option, using one stock to join in. When using two players, the first player will have priority over the screen, making it possible for the second player to get run off the screen if the two players are not coordinated. However, the second player has the option to [[Space Jump|warp]] to the first player at any time (except in boss battles) by pressing the [[Start-Pause button|button that would normally pause the game]]. The first player must be present with stock left at all times; if the first player is defeated with no spare stock remaining, the game will end and offer a continue. If the second player is defeated, the first player can continue alone. In addition, only the first player can navigate through [[door]]s (though the second player can still utilize [[key]]s) and temporary switches. If the second player goes into a barrel cannon or minecart they will be teleported back to the player seconds later unless the first player goes in right after. The second player can also decide when barrel cannons shoot.

When playing a level for the first time, many cutscenes will pause just before gameplay begins, showing a view of all available characters. A message will display how many stock the level allows, and a cursor will appear that allows choosing which characters to play. The order characters are chosen in is the order they will appear: they will cycle through in that order until all stock is depleted. Playing through a level again, there will be a screen before the level allowing choosing between any available characters instead of cutscenes during the level. This can be both an advantage and a disadvantage: there is a wider character variety to choose from, but one cannot pick less characters than the number of stocks the stage has (meaning if a stage has four stocks, the player must choose four characters). Additionally, no mid-level cutscenes will play, including ones that would normally allow a re-pick of characters that replenishes stocks. While on many levels this makes little difference, it is very problematic on long stages like the second Subspace Bomb Factory, where a replay provides only a fraction of the stock originally given.

The physics of many (if not all) characters are also tweaked slightly. In general, characters run slower, fall faster, and jump better than in brawls. However, the [[midair jump]]s of a character that possesses more than one will be worse than normal. Move mechanics are not altered, although the differing jump heights, jump timing, and gravity will change how effective aerial attacks are. The most significant change is the removal of stamina from Pokémon Trainer's Pokémon, which allows one to use one Pokémon exclusively. Characters are also able to [[swimming|swim]] for significantly longer. Characters retain their standard physics in boss battles. Because Smash relies on KOs by being knocked off stage, in order for the platforming nature to be retained, the camera's reaction time in following a character decreases in proportion to the player's damage.  

[[Grab]]bing mechanics are also altered. Normal enemies cannot be held onto for any length of time; they will be thrown immediately after being grabbed, making it impossible to [[pummel]] them. This means that choosing which throw to use must be done with the Control Stick during the grab animation; inputting no direction will result in a forward throw (with the exception of {{SSBB|Donkey Kong}}, who cannot carry enemies, and instead will utilize his up-throw). Special moves that involve grabbing will fail to grab, like Yoshi and Kirby's standard special moves; such moves have extra Subspace Emissary-only hitboxes (for example, [[Egg Lay]] will deal 13% damage, while Pikmin will deal damage when [[Pikmin Throw|thrown]]). Bosses and large enemies cannot be grabbed; however, Big Primids can be grabbed effectively. None of these changes apply when facing an opposing Smasher due to playing like an actual Brawl, though Kirby will be unable to copy their abilities.

Like most other single-player modes, one can select different difficulty levels to play The Subspace Emissary. At the creation of a new game file, the player may select a "default" [[difficulty]] from Easy, Normal, Hard, Very Hard, and Intense. Stages normally use this default difficulty (which cannot be changed), although the difficulty of a stage can be altered before it is begun. The game keeps track of the hardest difficulty level at which each stage has been cleared, and when a stage is selected, it suggests a difficulty higher than the highest completion level.

As one selects higher difficulties, the game makes these adjustments:

*Enemy health goes up, sometimes considerably with bulky enemies like Greaps.

*Enemies' AI generally get smarter (such as attacking more often, or [[Bytan]]s duplicating nonstop).

*More (and sometimes deadlier) enemies appear during locked battles.

*Less favorable items appear, although an increased number of stronger healing items appear when enemies are defeated.

*[[Stock Ball]]s may get rarer (or, in the case of Very Hard and Intense, not exist, being replaced by recovery items instead).

*Certain features travel faster, giving the player less reaction time.  

**Auto-scrolling areas scroll faster.

**Moving walls, floors, and ceilings move faster, making characters more easily [[KO|crushed]].

*Wind speeds increase (including the wind from a [[Borboras]]), sometimes to nonsensical levels.

*More, higher quality, and rarer stickers appear.

*More coins are given at the end of each level.

When only one character is available in Co-op mode, P2 will control an alternate costume of that character. This happens in nine stages: Kirby (in the Midair Stadium vs Petey Piranha and the entirely of Subspace II),  Pit (in The Skyworld, before having Mario join), Lucas (in The Ruined Zoo when he runs from the statue), Marth (in The Battlefield Fortress, before joining Meta Knight and Ike), Zero Suit Samus (in The Research Facility before she joined Pikachu), Meta Knight/Lucario (in The Glacial Peak, only in the battle against the character P1 didn't choose), Snake (in the Battleship Halberd Interior, before he joined Meta Knight and Lucario) and King Dedede (in the Subspace I, only in the battle against Bowser). A ninth battle is at the beginning of the game, where Mario and Kirby duel. This also applies to Diddy Kong when replaying any stage after completing the Jungle before completing the Lake.

Due to these battles being against smashers or slightly modified versions of them, they are fought like regular brawls. Note that the player characters listed are only mandatory for the first playthrough and that other characters may be used if the level is replayed.

'''Note:''' When only one character is available to fight a boss or mini-boss in Co-op mode, the second player plays as a [[color change]] of that character. This is the only way to play as a character’s alternate costume outside of replaying a stage where a character is battled, selecting this character as any stock aside from the first and not losing enough stocks to spawn as the character before the player activates the battle, in which afterwards the player should lose enough stocks so that they spawn as this character. This only happens in four battles: Mario/Kirby vs the character not chosen by P1, Kirby against Petey Piranha, Meta Knight/Lucario against the character not chosen by P1, and King Dedede against Bowser.

*[[Porky Statue]] (The Ruined Zoo): it chases Lucas but it does not fight with him.

Some segments in levels, or all a level, has a battle with some enemies from Subspace. Unlike ambushes during sidescrolling segments, red dots on screen are used to indicate how many enemies are left to defeat.

''The Subspace Emissary'' contains gameplay elements similar to the sub-games of ''[[Kirby Super Star]]'' and other elements from ''Kirby'' games. This is likely intentional, given [[Masahiro Sakurai]]'s work on both games.

*The Halberd plays a very strong role in both games, and in both, it's destroyed and crashes in the ocean.

*The beginning of [[The Ruined Zoo]] (more specifically the boss battle against the [[Pig King Statue]] and [[Porky Minch]]) is similar to the Heavy Lobster battle in ''Revenge of Meta Knight'': The player is chased by the boss, who remains invincible for this duration and plows through anything in its path. Following the chase, the boss becomes vulnerable and attacks the player head-on.

*Both feature {{b|minecart|vehicle}}s and [[Slide Launcher|special devices]] that propel characters forwards. The latter's design and function comes directly from ''Kirby Super Star''. Additionally, the slide launchers puts characters in a shield position, just like in ''Kirby Super Star''. There are also bomb blocks which function identically to those from the ''Kirby'' series.

*The [[Space Jump]] is just like how P2 from ''Kirby Super Star'' comes back to P1.

*Bosses from the ''Kirby'' games, such as {{iw|wikirby|Dyna Blade}} and Marx, have similar moves to bosses in ''Brawl'', such as Ridley and Tabuu.

*[[Roader]]s are similar to ''Kirby'''s {{iw|wikirby|Wheelie}}s.

*The planet Floria in Milky Way Wishes has a similar concept to the [[Door#Day-changing doors|day-changing doors]], except that it has four rooms and they are based on seasons instead of day and night.

Despite characters using the same moves and using much of the same engine as in the other modes of ''Brawl'', the gameplay of the Subspace Emissary differs from that of ordinary [[Versus mode|brawls]]:

*The walking speed, running speed, and [[air speed]] of most characters has been normalized; slower characters move faster, while faster characters move slower. This is quite noticeable with Captain Falcon and Sonic's dashing.

*Player 2 will receive a significant walking speed, running speed and jump height increase as their distance from player 1 increases. This is presumably to prevent them from falling behind too much, but happens regardless of whether they run ahead or fall behind.

*All characters jump 2 frames faster, jump 18% higher, have slightly higher gravity, and have a 19% faster falling speed. As a result, vertical movement is in general faster, while some characters' recoveries (such as Jigglypuff and Pit) are indirectly [[nerf]]ed by the heavier physics.

**Peach's double jump has 40% more force; no other character has a change of more than 10%.

**Snake's double jump has 12% less force.

**Some special moves that grant temporary hovering, such as Diddy's [[Rocketbarrel Boost]], can't keep up with the increased gravity and so are also indirectly nerfed.

*During side-scrolling stages, the player cannot get [[Star KO]]'d - the player crashes into the top of the screen, leaving behind the colorful explosion. Players are only Star KO'd or Screen KO'd in ambushes, boss battles, and fights against Subspace clones.

*All characters can [[swim]] considerably longer.

*The [[Pokémon Change#Stamina|Stamina]] mechanic of the {{SSBB|Pokémon Trainer}}'s Pokémon is removed.

*Grab-only special moves such as [[Inhale]] and [[Egg Lay]] deal damage to enemies instead of grabbing.

*In addition to blocking most attacks, [[Mirror Shield]] can also now do damage.

While various characters in the ''Smash'' series have one-liners through [[taunts]], battle cries, and the like, the cutscenes of ''The Subspace Emissary'' have very little spoken dialogue. The vast majority of character interaction takes place through actions, gestures, and expressions, augmented by short grunts or exclamations. Some cutscenes feature moves that have battle cries where the character says the move's name, such as Ness and Lucas using their [[PK Thunder]] or Captain Falcon using his [[Falcon Punch]]. The only character who speaks in more than one scene is Pikachu, who only "speaks" via yelling its own name. In Jigglypuff's only scene, the crowd chants its name, making them the only non-playable character to say a line.

Only one character in all of The Subspace Emissary ever speaks in a full sentence; in [[Battleship Halberd Interior]], {{SSBB|Snake}} directly says to the player, "Kept you waiting, huh?" after revealing himself. This is a classic line from the ''Metal Gear'' series. In ''Brawl'', it references the extensive voicework in the ''Metal Gear Solid'' games, the frequent [[wikipedia:Fourth wall|breaking of the fourth wall]] in the series, and the fact that the player had seen a brief glimpse before already in a much earlier cutscene.

*The Subspace Emissary's camera is programmed to only be able to move through certain area, and will lock if the player goes outside these areas. However, if the player goes a sufficiently large distance above or below the stage's vertical origin, this restriction will inexplicably be bypassed. It's possible that this was programmed in as a failsafe, but this is never possible in normal gameplay, due to the game using a local blast zone system based on the camera's location, and the different behaviour of the upper blast zone. Thus, this phenomenon can only occur if the local blast zones are modified to extend much further out.

*While the mode effectively encourages players to use almost every character in the game, it is possible to complete The Subspace Emissary using as few as twelve characters, or barely one-third of the roster: {{SSBB|Kirby}}, {{SSBB|Pit}}, {{SSBB|Lucas}}, {{SSBB|Marth}}, {{SSBB|Zero Suit Samus}} (transforming from Samus by taunting whenever Samus must be chosen), {{SSBB|Snake}}, {{SSBB|Meta Knight}}, {{SSBB|King Dedede}}, {{SSBB|Diddy Kong}}, either {{SSBB|Link}} or {{SSBB|Yoshi}}, either {{SSBB|Olimar}} or {{SSBB|Captain Falcon}}, and one of either {{SSBB|Peach}}, {{SSBB|Zelda}} or {{SSBB|Sheik}}.

**Co-op mode adds {{SSBB|Mario}}, {{SSBB|Ness}}, {{SSBB|Donkey Kong}}, {{SSBB|Fox}}, Pokémon Trainer's {{SSBB|Squirtle}}, {{SSBB|Ice Climbers}} and {{SSBB|Pikachu}} alongside both pairs (instead of just one) of Link and Yoshi, Olimar and Captain Falcon, Peach and either Zelda or Sheik to the required list.

*Assuming the player rescues no other characters in either [[Subspace (Part I)|Subspace I]] or [[Subspace (Part II)|Subspace II]], it is possible to finish The Subspace Emissary with only 6 characters available in the player's roster: {{SSBB|Luigi}}, {{SSBB|Ness}}, {{SSBB|King Dedede}}, and {{SSBB|Bowser}} from Subspace I, {{SSBB|Kirby}} from Subspace II, and {{SSBB|Sonic}}, who appears at the end of the [[Great Maze]].

*[[Palutena]] is the only character in The Subspace Emissary who is neither a villain/enemy nor playable.

*As far as playable characters go, {{uv|Wario}}, {{uv|R.O.B.}}, and {{uv|Sonic}} are the only universes that do not have a song played at any time.

**In addition, {{uv|Star Fox}} (excluding the hidden room in The Ruins) and the universes mentioned above are the only universes that do not have a song played in normal gameplay.

*Outside of the boss characters, the ''Super Mario'' universe is the only represented franchise that uses some of its characters as regular enemies, those being Goomba, Koopa Troopa/Paratroopa, Bullet Bill, Hammer Bro, and Giant Goomba. All of the other enemies are original characters.

*{{SSBB|Mario}} and Kirby are playable in more levels than any other character, with a total of nine.

**Pit is playable in eight levels; Link, Yoshi, and Diddy Kong are playable in seven; Peach or Zelda, Lucas, Pokémon Trainer, Meta Knight, and Samus and Pikachu are playable in six (if one count all Pokémon Trainer's Pokémon ({{SSBB|Squirtle}} appears in all six levels, {{SSBB|Ivysaur}} appears in four levels, and {{SSBB|Charizard}} appears in three levels) and both of Samus' versions ({{SSBB|Zero Suit Samus}} appears in the first two levels, and Samus in the last five levels)), Zelda or Peach, {{SSBB|Donkey Kong}}, and {{SSBB|Fox}} are playable in five; {{SSBB|Lucario}} can be playable in four or five; Marth, {{SSBB|Ike}}, {{SSBB|Falco}}, Captain Falcon, Olimar, and Snake are playable in four; {{SSBB|Ness}}, {{SSBB|Ice Climbers}}, and {{SSBB|R.O.B.}} are playable in three; {{SSBB|Mr. Game & Watch}}, {{SSBB|Luigi}} and {{SSBB|King Dedede}} are playable in two; {{SSBB|Bowser}}, {{SSBB|Ganondorf}}, {{SSBB|Wario}}, and {{SSBB|Sonic}} are playable in one; and {{SSBB|Jigglypuff}}, {{SSBB|Toon Link}}, and {{SSBB|Wolf}} are absent until after completing The Subspace Emissary.

*The opening battle between Mario and Kirby in The Subspace Emissary may be a reference to the [[opening movie]] of ''[[Super Smash Bros.]]'', where the two face each other near the end of the movie.

**In addition, Mario's [[trophy]] coming to life in the first cutscene could be a reference to the beginning of ''[[Melee]]'''s opening movie.

*The Subspace Emissary is the only mode in the ''Smash Bros.'' series thus far that allows players to unlock characters without fighting and defeating them. ''Ultimate''{{'}}s [[World of Light]] bypasses the usual "Challenger Approaching" battle, but it still requires the player to fight the character that will be unlocked.

*The Subspace Emissary is mentioned several times in {{forwiiu}} in [[Palutena's Guidance]] during the conversation of Mario and [[Mr. Game & Watch]] and the North American English boxing alias for [[R.O.B.]] Also, some enemies from The Subspace Emissary return in {{for3ds}}'s [[Smash Run]] mode. The Subspace Emissary is also referenced in one of the riddles regarding Tabuu, located in the [[Mysterious Dimension]] sub-world of World of Light.

*The health bars for [[enemies]] (not including [[boss]]es) are compressed at the left hand side, so a length of health bar represents more health at the left of the bar than the right. This makes attacks appear to deal less damage the closer an enemy is to dying.

*While all characters use their in-game models during cutscenes, certain parts of characters such as loose clothing and hair have increased polygon counts in order for them to perform smoother. Examples of this are Marth's cape, Link's hair, and Lucas's shirt.
