StreetPass Mii Plaza

StreetPass Mii Plaza is a pre-installed application on the Nintendo 3DS developed by Nintendo that relies heavily on StreetPass connectivity to play its games. It allows players to create a profile using any Mii that they have made in the Mii Maker, which will be sent to other users via StreetPass when connected, and used to play games. Two games (three after the December 2011 update and seven after the June 2013 update) which utilize the player's Mii can be played in the Plaza: Puzzle Swap, Find Mii, Mii Force, Flower Town, Warrior's Way and Monster Manor. The game's only unlockables are Nintendo-themed accessories which can be used to dress up the player's Mii, and three dimensional scenes featuring recent Nintendo games or events.

Features
StreetPass Mii Plaza allows the creation of a profile that players can customize with their personal information, which is sent to other users upon connecting via StreetPass. This information includes a Mii, which is used as a player character while in the Plaza, a greeting, a birthday, the 3DS' registered location and minor details such as a favorite hobby or dream. Players can choose to make some of this information private if they wish, and can change the information in the Settings sub-menu at any time. As long as the player has the wireless communications switch turned on, StreetPass enabled, and the system closed, the data is transferred between any wireless-enabled 3DS system within range. A notification light on the 3DS turns green to indicate when another 3DS has been detected, even when the software is closed.

StreetPass Plaza is the location where the player's Mii resides. The Plaza is lush with green lawn and small plants, and features a yellow arch adorned with a grass root as its front entrance. Initially it begins empty and the music begins quiet, but as additional Miis are invited into the plaza via StreetPass and online games such as Mario Kart 7 or Mario Tennis Open, the plaza grows, and the music becomes more dynamic. Upon opening the software after a connection has been made, the front gate of the Plaza is shown with the player's Mii greeting any new Miis that have been encountered while the system was closed, before inviting each to take residence in the plaza and play Find Mii and Puzzle Swap with them, as well as any additional games that they have purchased.

The player is given the option of playing two games (three games after the December 2011 update and seven games after the June 2013 update) to unlock accessories and 3D images related to various Nintendo series, by using either Miis obtained by StreetPass or Play Coins. After the December 2011 update, additional features were introduced, including a slideshow for completed Puzzle Swap panels, a world map which shows locations that differ to the player's, an achievements list, and a music player for listening to the application's various tracks. After the summer 2013 update, a Shop menu was added, where four more StreetPass games can be purchased. The touch screen was also updated to allow for quick access to each of these games, as well as Find Mii and Puzzle Swap. Other features such as an Exchange Booth for unlocking outfits and a Check for Updates tool were also introduced.

Puzzle Swap
Puzzle Swap features various different puzzles that the player can complete. Players are given one piece to start off with, and more can be obtained by StreetPassing with other people. After StreetPassing with someone, the player is then entitled to take a puzzle piece from them (and vice versa) and add it to their collection. If another player does not have any new pieces, nothing is gained. Players can also spend two Play Coins to buy a random puzzle piece to any incomplete puzzle they have. However, the puzzle piece may be a copy of any earlier acquired pieces, and will be of no use. Once a puzzle is completed, a three-dimensional image of the puzzle can then be viewed.

While the initial puzzles consisted of fifteen pieces, the December 2011 update included several puzzles with either twenty-four or forty pieces, as well as the ability to receive new puzzles through SpotPass. Additionally, the four center-most pieces in the twenty-four piece puzzles and the eight center most pieces in the forty piece puzzles are pink. These pink pieces cannot be purchased with Play Coins, and can only be obtained by StreetPassing other people who have obtained them.

 * Super Mario Galaxy 2 (15 pieces)
 * New Super Mario Bros. Wii (15 pieces)

Find Mii
In Find Mii (called StreetPass Quest outside of North America), Miis are utilized to fight their way through several enemy-filled rooms to free the player's Mii from imprisonment. Mario-themed accessories such as character caps can be obtained and later be used to dress up the Miis. When another 3DS is detected, its profile Mii will join in on the game. Players can also hire a wandering hero for two Play Coins, with a limit of up to ten in a single party. However, these heroes are usually very weak (Level 1 or 2) and take the appearance of a dog or a cat depending on the players' preference for cats or dogs which can be adjusted in the Settings menu.

A sequel to Find Mii, known as Find Mii II (StreetPass Quest II outside of North America) was made available in the December 2011 system update. It is similar to the original, but features tougher challenges. It can only be played once the first Find Mii game has been cleared two times.

Enemies
In Find Mii and Find Mii II, the player has to fight through several enemies in order to save their Mii. The following are the lists of enemies encountered during the quests:

Find Mii

 * Ghost: The yellow ghost which is also the main ghost, easy to defeat. 7 HP (10 in Find Mii II)
 * Blue Ghost: A blue version of the main ghost with a curl near its head. Due to having more HP, they are harder to defeat. In addition, Blue Ghosts are impervious to blue magic while being weak to red magic. 25 HP
 * Blood Ghost: A bigger red version of a normal ghost with a more menacing look and higher health. Blood Ghosts are invulnerable to red magic while being weak to blue magic. 50 HP
 * Armored Ghost: A suit of armor with eyes inside the helmet, these ghosts are like normal ghosts, albeit with more health and that they reduce sword damage by one, meaning only level two heroes and up can deal damage with their swords, unless level 1 heroes were to get critical hits. 10 HP (20 in Find Mii II)
 * Armored Demon: A bigger blue version of Armored Ghosts. Like Armored Ghosts, they take one less damage from sword attacks. 20 HP (40 in Find Mii II)
 * Armored Fiend: The final normal ghost and the penultimate boss of the game only encountered at the top of Mirage Tower. This ghost guards the player's Mii and must be defeated, like every other armored ghost. It shares the same traits of the Armored Ghost and Armored Demon. 60 HP
 * Ultimate Ghost: The final boss of the game encountered after defeating the Armored Fiend, this purple ghost takes several hits to actually defeat, but teams of different ranked warriors will defeat the ghost. It is also the second boss of the last stage in Find Mii II. 145 HP (150 on second encounter and in Find Mii II)

Find Mii II

 * Yellow Slime: An enemy that is similar to the Ghost, albeit with a slightly higher evasive rate. Yellow Slimes are weak to yellow magic, a trait shared with most other slimes. 10 HP
 * Blue Slime: A slime that is capable of using Healing Magic. Just like Yellow Slimes, Blue Slimes have a slightly higher evasion rate compared to most enemies. Blue Slimes are weak to yellow magic, as with most other slimes. 25 HP
 * Green Slime: A slime that possesses the highest evasion rate in the whole game, but also the lowest HP of all enemies encountered in the game. Unlike most slimes, it is not weak to yellow magic and is immune to red, blue and purple magic. However, it can be frozen or put to sleep with either light blue or light green magic. This helps lower its evasion rate. 3 HP
 * Pink Slime: A slime that uses Growth Magic every time it takes damage. If it grows four times (to where it will become the size of the player's screen), it will end the player's session, and all the heroes will flee. 50 HP
 * Reaper Cadet: An enemy that is capable of spewing curse gas, which might make a hero lose their turn to use their sword or magic while fighting. Just like with armored enemies, Reaper Cadets take one less damage from sword attacks. However, they also take one less damage from magic attacks. Reaper Cadets are weak to white magic. 30 HP
 * Reaper Captain: A reaper that has the ability to spew barrier gas, which nullifies the ability for heroes to use magic. Just like with the Reaper Cadet, the Reaper Captain will take one less damage from sword and magic attacks. Reaper Captains are weak to white magic, as with other reapers. 45 HP
 * Reaper Commander: A reaper that, like Cadets, will spew curse gas, which makes it so that heroes may lose their turn while fighting. Like other reapers, the Commander takes one less damage from sword and magic attacks. Just like Blue Slimes and Roaming Mummies, Reaper Commanders have the capability of using Healing Magic. 60 HP
 * Reaper General: A reaper that will, like Cadets and Commanders, spew curse gas. Unlike other reapers, the Reaper General takes two less damage from sword and magic attacks instead of one. In addition, the Reaper General can use revival magic, which (hence the name) will revive his defeated allies. 75 HP
 * Granite Golem: An enemy that takes two less damage from sword attacks. 25 HP
 * Iron Golem: A stronger variation of the Grantite Golem that guards the princess in the normal quest, while two of them appear in the flaming rooms in the secret quest. 45 HP
 * Golden Golem: The second strongest golem that heroes fight. Just like other golems, it takes two less damage from sword attacks. However, unlike other golems, the Golden Golem is weak to black magic. However, not only does black magic deal major damage to the Golden Golem, but it also cancels their defense. 80 HP
 * Diamond Golem: The strongest golem encountered. It guards the princess in the Secret Quest. After each turn, it will use Fortifying Magic to increase its defense further. Like the Golden Golem, the Diamond Golem is weak to black magic, and just like the Golden Golem, black magic will also negate its defense, though it will still use Fortifying Magic. 85 HP
 * Shambling/Wandering Mummy: An enemy that has the ability to scare the first hero in line when first encountered by ambushing them. Shambling Mummies are weak to red magic, a trait shared by all other mummies. 15 HP
 * Roaming Mummy: A mummy that resembles a larger, blue version of the Shambling Mummy. Just like the Blue Slime, it is able to use Healing Magic. It will attempt to scare the first hero in line when encountered. Like other mummies, it is weak to red magic. 30 HP
 * Marauding Mummy: A mummy with red bandages and spikes on its head. It has the same trait with other mummies. It is usually encountered with Roaming Mummies. Like other mummies, it is weak to red magic. 45 HP
 * Rampaging Mummy: The strongest mummy encountered. Unlike other mummies, it will always scare the first hero in line. Being a mummy, it is weak to red magic. 60 HP
 * Armored Archfiend: A massive Armored Ghost, teamed heroes can take him out easily. It uses Fortifying Magic to increase its defenses. 60 HP
 * Dark Lord: The final boss of the game and the true leader of the monsters. Just like the Ultimate Ghost, he spews Level-Down Gas, which weakens heroes by one level (level 1 heroes are unaffected). In addition, the Dark Lord is invulnerable to purple, light blue, and light green magic. 200 HP

Magic
In Find Mii and Find Mii II, each hero has a different magic spell. The magic's effect depends on the hero's shirt colour. In Find Mii II, Combo Magic can be used with heroes of the same shirt color. Certain enemies will also use magic for defence. Magic can also be used to remove hazards before entering a room. This is a list of all magic performed in the game.
 * Red: A flame-based attack that hits all enemies in a room. It is especially effective against Blue ghosts and mummies, and is resisted by Blood ghosts. When used as combo magic, the attack is stronger and can be used to thaw a frozen room.
 * Blue: An attack that douses the enemy in water. It is especially effective against Blood ghosts and resisted by Blue ghosts. When used as combo magic, the attack is more powerful and can be used to cool a fiery room.
 * Light Blue: An ice based attack that freezes all enemies in a room. Frozen enemies cannot move and have their evasive rate lowered significantly. Heroes may attack a frozen enemy consecutive times until it thaws. Combo magic increases the time enemies take to thaw out.
 * Green: Doubles the level of the next hero in line (Maximum level: 7). When used as combo magic it maximises the level of the next hero in line.
 * Light Green: Puts all enemies to sleep. Similar to the effects of Light Blue Magic, sleeping enemies cannot move and heroes may attack until the effect wears off. Like Light Blue Magic, when used as a combo it increases the time enemies take to wake up.
 * Purple: Poisons all enemies in a room. Poisoned enemies lose 1 HP after the end of each turn. When used as combo magic, enemies lose 2 HP at the end of each turn.
 * Yellow: A room effect that whirls up a sandstorm. This decreases the accuracy of all heroes; however it may give them an extra chance to attack if the enemy rubs its eyes. When used as combo Magic a stronger sandstorm can be summoned and can be used to dispel poisonous gas in a room (such as the room found before the castle).
 * Orange: A room effect that invigorates all heroes. Each hero attacks 4 times instead of 3 while the spell is in effect. Combo magic gives each hero 5 attacks instead of 3.
 * Pink: A room effect that makes heroes feel daring. This greatly decreases the accuracy of all heroes, however all hits become critical hits while the spell is in effect. When used as combo magic, accuracy is still lost, albeit not as much as when solo is used.
 * Brown: Summons a bunny to fight. The bunny's level will be less than or equal to the level of the hero who summoned it. When used as combo magic, the bunny's level will be equal to the team's combined level (Maximum level: 7).
 * White: Used to light up a dark room. Reapers take double damage while the room is bright.
 * Black: Darkens a dazzling room. Sparkling golems take double damage while the room is darkened.

Enemy magic
In Find Mii II, some enemies use exclusive magic to defend themselves. Magic can be removed by a Bottled Barrier.
 * Mirage Magic: Used only by Blue Ghosts in Find Mii II. Creates an illusion to evade attacks. The illusion is still affected by magic, and is broken with one sword hit. However, the hero leaves if it hits an illusion.
 * Healing Magic: Used by Blue Slimes, Roaming Mummies, Reaper Commanders. It heals another enemy's HP.
 * Magical Armor: Used by Armored Ghosts. Whenever a hero targets an Armored Ghost's ally, it will use its magical armor to take the hit and make it become the hero's target.
 * Growth Magic: Used by Pink Slimes. Each time it takes damage, it uses it to grow bigger. After growing four times, it will fill the entire screen, and every hero will flee.
 * Fortifying Magic: Used by Diamond Golems and the Armored Archfiend to increase defense.
 * Reviving Magic: Only used by the Reaper General. It completely revives a fallen enemy.

Potions
Also exclusive to Find Mii II, potions can be bought in exchange for Play Coins.
 * Vial of Valour (8 Play Coins): Calls back any heroes who had failed to defeat the monster.
 * Power Potion (20 Play Coins): Boosts the level of the next heroes in line, similar to green magic.
 * Dispelling Draft (2 Play Coins): Blows away gas spewed by enemies.
 * Bottled Barrier (2 Play Coins): Nullifies enemy magic.

Paid Games (DLC)
The option to purchase 4 additional StreetPass games becomes available after updating the software. These games can be purchased individually, or all at once for a discount. StreetPassing players who have also purchased one of these titles allows for additional, individualized bonuses to be obtained within the games they share.

Mii Force
Mii Force (known as StreetPass Squad in PAL regions) is the first of the four games that was added to StreetPass Mii Plaza in 2013. The goal is to save the StreetPass Galaxy from the Goldbone Gang. As the user gets more StreetPass Tags, the more weapons the user can use to get rid of the Goldbone Gang. When the user gets hit then one of the helpers will leave. Each level ends with a boss.

Flower Town
Flower Town (known as StreetPass Garden in PAL regions) is the second of the four games that was added to StreetPass Mii Plaza in 2013. The goal is to grow 80 different species of flowers. Each Mii that visits the player's garden, either makes the current flower grow or pollinates one of its seeds. The player can decorate their garden with flowers and accessories. Players are also able to change the pots that their plants are in. Some Mario-themed pots are the Green Pipe, Yellow Pipe, and Brick Planter. The Mega Mushroom Flower resembles a Super Mushroom, and the Bite Weed is similar to a Piranha Plant.

Warrior's Way
Warrior's Way (known as StreetPass Battle in PAL regions) is the third of the four games that was added to StreetPass Mii Plaza in 2013. The goal is to take over the world with an army. To get soldiers, the player must get a StreetPass Tag which grants soldiers that equal that person's plaza population. Another way to get soldiers is to win a battle. If a battle is lost, some of the player's soldiers will depart. The player can also fight with the people who joined via StreetPass Tags if they have already owned Warrior's Way.

Monster Manor
Monster Manor (known as StreetPass Mansion in PAL regions) is the last of the four games that was added to StreetPass Mii Plaza in 2013. The goal is to solve a mystery in the mansion with the help of people the player meets via StreetPass Tags. Each plaza visitor will give a piece of a hallway in their color. If the player combines a piece of a hallway with the corresponding color to another, the pieces will become a room which may contain treasure chests. The player must also engage in a duel with monsters to progress using various weapons obtained from chests as well. The player must find a staircase to progress further in the game.

Outfits
During the Find Mii games, the Miis can find treasure chests that contain Hats. Hats can be worn by the captive Mii in a decorative way, some hats can only be collected by replaying the game. There are also Outfits and various other hats collected by spending tickets to buy them in the Exchange Booth.

Exchange Booth
The Exchange Booth is where the player exchange tickets obtained from the June 2013 games for outfits. It is unlocked upon purchasing of one of the paid StreetPass games.
