'''''New Super Luigi U''''' (stylized as '''''New Super Luigi <s>Bros.</s> U''''') is an expansion game for ''[[New Super Mario Bros. U]]'', released as part of the [[Year of Luigi]], celebrating the thirtieth anniversary of Luigi's initial debut. It features [[Luigi]] as the main player, with [[Yellow Toad and Blue Toad|Yellow Toad]], [[Yellow Toad and Blue Toad|Blue Toad]], and notably, [[Nabbit]] (who replaces [[Mario]] from the original game) playable in multiplayer mode.<ref name="Nintendo Direct"></ref> Although it refers to him, the game does not feature Mario himself at all.
The title was first released on the [[Nintendo eShop]] on [[Wii U]] for region price as downloadable content for ''New Super Mario Bros. U''; the game must be updated to version 1.3.0 before ''New Super Luigi U'' can be accessed in-game, and requires 731.4 MB of memory to be installed. Once downloaded, the prompt to access the Nintendo eShop to download the expansion is replaced with a prompt to go to the main menu for ''New Super Luigi U''. Support for the Wii U Pro Controller is also included in addition to {{button|wii|Wiimote}} and the {{button|wiiu|GamePad}} controls in ''New Super Mario Bros. U''. The game was later released at retail as a standalone game for region price, not requiring ''New Super Mario Bros. U'' to play. Both games were later released in a compilation known as ''[[New Super Mario Bros. U + New Super Luigi U]]'', initially included exclusively in the Mario & Luigi Wii U Deluxe Set bundle, but later released as a standalone [[Nintendo Selects]] disc at a price cheaper than either game individually (the precise price is dependent on the region). This game was also included in ''[[New Super Mario Bros. U Deluxe]]'' for the [[Nintendo Switch]]. The DLC was later removed from the Wii U eShop due to its discontinuation on March 27, 2023, making it no longer possible for players to purchase it. However, players who purchased the DLC before this date can still play it as long as it is on their Wii U device.
==Gameplay==
[[File:NSMBU and NSLU Physics Comparison.jpg|thumb|left|upright=1.1|Comparison of the jump physics in both games.]]
The gameplay is largely similar to its base game, except that the playable characters retain Luigi's higher jump and lower traction from ''[[Super Mario Bros.: The Lost Levels]]''. The game has been designed to be more difficult, with each stage starting at only 100 seconds; due to this, however, the courses have also been made shorter than normal while also being packed with enemies and obstacles. While the levels have all been altered from the base game, the world map itself has not been. Elements like [[List of items|item]]s, [[List of power-ups|power-up]]s, [[Star Coin]]s, [[Toad House]]s, [[Enemy Course]]s, and bosses are retained as such.

The multiplayer of ''New Super Luigi U'' is also retained from ''New Super Mario Bros. U''. However, because Mario is not featured in this game, [[Nabbit]] is instead used as the fourth playable character. As Nabbit, the player cannot take damage from enemies, but cannot use most power-ups, Yoshis, or hold items. Any power-ups Nabbit collects but cannot use are converted to [[Extra life|1-Up]]s at the end of each stage. Only eight 1-Ups can be earned per course through this method.<ref name="NabbitManual">{{cite|title=''New Super Luigi U'' Wii U electronic manual|language=en-us|format=PDF|date=2013|page=12|publisher=nintendo.com|accessdate=March 7th, 2025|url=https://csassets.nintendo.com/noaext/image/private/t_KA_PDF/manual-WiiU-New_Super_Luigi_U?_a=DATC1RAAZAA0}}</ref> 

Players can earn power-ups from Toad depending on the time left upon completion of the level. At 088, a [[Super Star]] is given; at 077, a [[Super Acorn]]; at 066, a [[Mini Mushroom]]; 055, an [[Ice Flower]]; 044, a [[Fire Flower]]; and 033, 022, and 011 a [[1-Up Mushroom]].

==Changes==
[[File:NSLU Mario Block Sprite.png|frame|A [[Luigi Block]]]]
[[File:NSLU Single Player Gameplay.png|thumb|left|upright=1.2|The game features changed design and assets]]
The world map itself is unchanged from ''[[New Super Mario Bros. U]]'', but the levels have received a drastic makeover. As mentioned above, playable characters and their abilities have changed. The [[Time Limit|timer]] for each level is also set to start from 100 seconds and a 100-seconds time bonus is added to the timer after going to the boss door in the [[tower]]s and [[castle]]s (150 seconds in [[All Aboard!]] and 250 seconds in [[The Final Battle (New Super Luigi U)|The Final Battle]]). Items in [[Toad House|Red Toad House]]s may vary as well. For example, a [[1-Up Mushroom]] is in place of a [[Super Mushroom]]. Similarly, [[Enemy Course]]s contain only [[Mini Mushroom]]s and [[Propeller Mushroom]]s, as opposed to only [[Super Star]]s. Some enemies such as [[Grrrol]]s and [[Sumo Bro]]s. may appear earlier than their equivalent levels in ''New Super Mario Bros. U'', while some others such as [[Rocky Wrench]]es and [[Amp]]s are completely absent from the game. There are no [[Checkpoint Flag]]s in any of this game's levels. Many elements of the game are colored green to emphasize Luigi, and all of the levels have a [[List of Luigi sightings in New Super Luigi U|hidden Luigi]] in a wall or platform ([[Flying Squirrel Ovation]] has two).

[[File:NSLU Flying Squirrel Ovation Luigi Sighting 2.jpg|thumb|upright=1.4|A Mii being used in Flying Squirrel Ovation]]
After the game is completed, a [[Luigi Block]] appears at the beginning of each level. This allows the player to switch to the original game's physics, with lower [[jump]]s and better traction. [[Nabbit]] is not affected by the block. Nabbit is also playable in single player mode if the player holds down {{button|wiiu|ZL}}/{{button|wiiu|ZR}} on the {{button|wiiu|GamePad}}/[[File:Wii U Pro Controller White.png|18px|link=Wii U#Pro Controller]] or {{button|wii|B}} on the {{button|wii|Wiimote}} while selecting a level. If the same trick is done on the Flying Squirrel Ovation level in [[Superstar Road#New Super Luigi U|Superstar Road]], the player's [[Mii]] is played as instead of Nabbit.

==Worlds== 
{{NSMBU map}}
There are 82 new courses replacing the original courses from ''New Super Mario Bros. U'' with different level names, while the world names are retained.

By the time the player reaches the castle grounds, it has been transformed into a lava-based area. Princess Peach's castle remains mostly unchanged on the outside but on the inside it is similar to [[Bowser's Castle]] from the previous installments. This world must be completed to beat the game.

|-
|[[File:NSMBU Luigi Jumping Artwork.png|100x100px]]<br>[[Luigi]]
|The game's protagonist. Luigi is flung from [[Peach's Castle]] by [[Bowser]] when sieges the castle. Unlike ''New Super Mario Bros. U'', Luigi [[scuttle]]s his legs when he jumps and has poor traction on the ground, similar to his appearance in some prior games. Unlike the prior game, [[Mario|his brother]] is not in this game.
|-
|[[File:NSMBU Artwork Yellow Toad and Blue Toad.png|100x100px]]<br>[[Yellow Toad and Blue Toad]]
|These Toads were having tea at Peach's Castle with Luigi when they were tossed. They have all the same moves and physiques as Luigi, and are only available to play as in multiplayer.
|-
|[[File:NabbitNSMBU.png|100x100px]]<br>[[Nabbit]]
|A masked [[rabbit]]-like thief. When the player is controlling Luigi in Story Mode, Nabbit appears in certain levels with stolen items and they are given to him when caught. If the player presses {{button|wii|CCZL}} on a [[Wii U]] controller or {{button|wii|B}} on a [[Wii#Wii Remote|Wii Remote]] while selecting a level, they play as Nabbit instead. In multiplayer, he is one of the four playable characters. Unlike Luigi and the Toads, he cannot use most power-ups, ride Yoshi, carry items, and carry other players. Further, other players cannot carry Nabbit. However, Nabbit is nearly invincible. He can walk through enemies and across spikes, though he receives knockback when he makes contact with tough enemies or bosses. He loses a life only when he falls down [[pit]]s or environmental hazards like [[lava]]. He can use [[Super Star]]s. Up to eight non-Super Star power-ups he collects become 1-Ups at the end of each course.<ref name="NabbitManual"/>
|-
|[[File:NSMBU Artwork Mii (Green).png|100x100px]]<br>[[Mii]]
|If the player attempts to play as Nabbit in Story Mode while selecting [[Flying Squirrel Ovation]], they appear as a green-clad Mii instead. This is likely because the [[Flying Squirrel Mario|Flying Squirrel form]] is required to complete this level, which is unavailable to Nabbit.
|}

===Yoshis===
The game features three differently-colored Baby Yoshis, each one with a special ability. They differ from the adult Yoshi in terms of gameplay. Being babies, they cannot be ridden, so characters must carry them throughout the levels. Baby Yoshis instantly eat almost any enemy that is in front of them. Unlike ''Super Mario World'', Baby Yoshis cannot mature into adults after eating enemies, instead remaining infants. Two types of Baby Yoshis found on the world map can be taken into any course, with the exception of [[fortress|towers]], [[airship]]s, and [[castle]]s.

|[[File:Yoshi FS.png|100x100px]]<br>[[Yoshi]]
|A dinosaur-like creature with a long tongue that can be ridden. Yoshi has a meter that tracks how many [[Fruit (Yoshi food)|fruits]] he eats. Eating five makes him lay an egg containing an item. Unlike Baby Balloon Yoshis and Baby Bubble Yoshis, Yoshi cannot be taken to other levels, instead waving goodbye to the player character once they reach the [[Goal Pole]]. In multiplayer, the number of Yoshis that appear in a level equals the number of player characters.

|[[File:NSMBU Iggy Artwork.png|100x100px]]<br>[[Iggy]]
|Iggy Koopa is fought in Soda Jungle and uses the four [[Warp Pipe]]s to run around the room and on the ceiling to make it trickier for the player to stomp on him as he uses his Magic Wand to shoot three spells, with some being his usual green flame, and the other being red skeleton orbs that generate [[Magmaargh]]s when they land in the lava below. When Iggy is stomped on, he will dash around the room in his shell using the pipes on the walls, which will switch him to the other side of the room. Unlike the other Koopalings where they spin in their shells and change directions at the edges or walls of the room, Iggy can actually change directions anywhere around the room during his duration in his shell.

Occasionally, he shoots [[Bull's-Eye Bill|Missile Bill]]s. He can also jump high in the air and ground pound the floor or platform, which makes him fire Bullet Bills on both sides of his blaster. The ground pound can also make the floating platforms appear after he comes out of his shell.

|[[File:LudwigNSMBU.png|100x100px]]<br>[[Ludwig]]
|Ludwig von Koopa is fought in Meringue Clouds and levitates in the air while making two clones of himself, and all three Ludwigs will blast spells at Luigi before dropping onto the ground. If one of the clones is jumped on, it will simply disappear. There are four ways to find out which is the real one. The one that is the real one fires three spells, while the clones fire two. The clones keep their eyes half-open, and tend to assume the real Ludwig's pre-battle idle pose while not levitating. The real Ludwig will also drop to the ground last, after the clones, as well as laugh while dropping. Finally, Luigi always looks at the real Ludwig if he can see him directly, just as he does with the other bosses. When the fight starts off, after shooting their spells, the clones disappear before landing. After the first stomp, the clones do not disappear. After the second stomp, not only do all three Ludwigs shoot faster, but swap positions, though the real Ludwig still shoots three spells.

|Bowser Jr. is fought on [[airship]]s. In Soda Jungle, Bowser Jr. uses his [[Junior Clown Car]] as a submarine, in which the player character must guide the Targeting Teds that Bowser Jr. shoots into his submarine. With every hit, he summons three Torpedo Teds from the left and right or from the ceiling and the floor. In Meringue Clouds, Bowser Jr.'s boss battle involves him in his Clown Car equipped with boxing gloves, which he uses to destroy the blocks the player is standing on. Bowser Jr. periodically throws Bob-ombs, which the player can use against him. However, in [[Peach's Castle (world)|Peach's Castle]], he cannot be defeated.

|[[The Final Battle (New Super Luigi U)|The Final Battle]]
|-
|[[File:BowserNSMBU.png|100x100px]]<br>[[Bowser]]
|Bowser is fought inside |Peach's Castle. The first part of his battle is similar to ''[[Super Mario Bros.]]'', where the player has to get to the other side and press the switch; alternatively, shooting several spellsalso works. This causes the axe to fall and make the bridge collapse, making Bowser fall. The gate then opens and Luigi moves on. When Luigi reaches the top of the castle, Peach is being held up in the tower. After this, Bowser Jr. shows up in his Junior Clown Car, and Bowser hops on top of the castle while he is huge. Bowser Jr. also fights the player. In order to defeat them, the player must jump on Bowser Jr., causing him to fall out of his Junior Clown Car. This allows the player to jump in and hover over Bowser to harm him. Like the Koopalings, he curls into his shell and spins around when hit. He is defeated after being hit three times by the Clown Car.

==Development==
During the development process of both ''New Super Mario Bros. U'' and ''New Super Mario Bros. 2'', the developers began to think of ideas for downloadable content for the two games. Both teams thought of expanding the secondary modes, ''New Super Mario Bros. 2'' being [[Coin Rush]], and ''New Super Mario Bros. U'' expanding on Boost Rush; in the end it was decided that ''2'' would be the game to receive content first, since it was being released first. However, during the development of the Coin Rush courses the team decided to scrap the idea of additional Boost Rush course packs and began to think of other ideas. The team then began experimenting with the idea of shorter but more difficult courses to replace the ones in the original game.<ref>[http://iwataasks.nintendo.com/interviews/#/wiiu/new-super-luigi-u/0/0 Iwata Asks : New Super Luigi U : Overtaken by New Super Mario Bros. 2]</ref>

Originally, the downloadable content was being made with Mario in mind. However, when the Year of Luigi came up during a meeting, it was decided that Luigi would be the focus instead.<ref>[http://iwataasks.nintendo.com/interviews/#/wiiu/new-super-luigi-u/0/1 Iwata Asks : New Super Luigi U : In on the Action]</ref> When it was decided to make Luigi the main character, the developers also decided that Mario would be kept out of the game. When deciding on a new fourth playable character, the original idea was to use three Toads, but when testing this it was deemed too confusing; the idea to use Nabbit as the fourth character then came up, reusing his ability to pass by enemies; around that time, the team had also been talking about adding something for beginners, and the idea to use Nabbit was kept.<ref>[http://iwataasks.nintendo.com/interviews/#/wiiu/new-super-luigi-u/0/2 Iwata Asks : New Super Luigi U : Nabbit Solves Multiple Issues at Once]</ref>

==Reception==
''New Super Luigi U'' was mostly received positively by critics. The game holds a 77 average on Metacritic based on 59 reviews<ref>[http://www.metacritic.com/game/wii-u/new-super-luigi-u]</ref>, and a 75.92% on GameRankings based on 36 reviews<ref>[http://www.gamerankings.com/wii-u/704055-new-super-luigi-u/index.html]</ref>. GameSpot's Peter Brown gave it an 8.5/10, stating, "Though the world map, themes, power-ups, and visual assets are 'old,' Luigi's physics and the level design at large rise to the top."<ref>[http://www.gamespot.com/reviews/new-super-luigi-u-review/1900-6410778/]</ref> Chris Carter of Destructoid gave the game an 8/10. He praises the game's design, stating that, "There are a lot of new concepts and designs this time around, and even if a large portion of them are re-used assets, they're remixed in a way that makes its own mark on the franchise."<ref>[http://www.destructoid.com/review-new-super-luigi-u-256692.phtml]</ref> Vince Ingenito of IGN gave the downloadable content a 7.3/10, citing that, "Its smaller levels, restrictive time limit, and floaty physics work well as a challenge mode add-on to an already terrific game," but criticizing that it, "[it] still feels more like an addendum to NSMBU [...] rather than something that stands out on its own."<ref>[http://www.ign.com/articles/2013/06/27/new-super-luigi-u-review]</ref>

Conversely, Chris Shilling of Eurogamer gave the content a 6/10, criticizing that, "It's not a bad game by any stretch of the imagination: the level design is still a cut above so many of Nintendo's peers. But by the series' consistently high standards, it qualifies as a disappointment."<ref>[http://www.eurogamer.net/articles/2013-06-24-new-super-luigi-u-review]</ref>. Edge also gave the game a 6, criticizing the game's stages by saying, "the quality of the level design is mixed: some stages feel claustrophobic yet others are surprisingly baggy, and few are considerate enough to accommodate four players." The writer goes on to say that, "At its best, New Super Luigi U is an exhilarating test of skill," but also criticizes the game by saying that, "on occasion it dangerously approximates a fan-made ROM hack," in the end saying that, "Some will undoubtedly find its challenge inviting, but others will rightly expect more ingenuity from Nintendo than this."<ref>[http://www.edge-online.com/review/new-super-luigi-u-review/]</ref> GamesRadar writer Henry Gilbert, giving the game 3/5 stars, also says that, "If you’re ready for the heightened difficulty of solo play in New Super Luigi U, then you’ll find it rewarding. Otherwise, it’s a taxing platformer that’s only made more rage-inducing in multiplayer."<ref>[http://www.gamesradar.com/new-super-luigi-u-review/]</ref>

|align="left"|"''If you loved New Super Mario Bros. U., getting Luigi U is a no-brainer, as it features a collection of superior levels and an interesting re-work of Luigi as a character. If you weren't crazy about the game however, you may want to wait a bit. For those of you who have some patience, the game is launching later on in July and August (EU and US respectively) as a full standalone retail disc for $10 more that will not require the core game.''"

|6/10
|align="left"|"''What's most surprising about New Super Luigi U is that Nintendo has already proven it can transform a game through DLC. New Super Mario Bros. 2's downloadable challenge packs made a slightly lacklustre Mario game that much better, offering smart, creative twists on existing ideas. This, by comparison, just feels like an expansion pack, offering shorter, harder levels and nothing else. It's not a bad game by any stretch of the imagination: the level design is still a cut above so many of Nintendo's peers. But by the series' consistently high standards, it qualifies as a disappointment.''"

|7.3/10
|align="left"|"''New Super Luigi U is the chance the taller brother has waited for since being relegated to “player 2” status so many years ago. Its smaller levels, restrictive time limit, and floaty physics work well as a challenge mode add-on to an already terrific game. But as fun as it often is, this still feels more like an addendum to NSMBU – a remix, rather than something new that stands on its own.''"

|8.5/10
|align="left"|"''Nintendo has done a good job of creating a "new" experience out of old rags. You're still on a quest to rescue Princess Peach, and the same old Mario mechanics persist, but the challenges along the way feel different. Never have levels been this short, nor the emphasis on perfection so explicit, and these elements work in New Super Luigi U's favor. You don't need to be an expert player to save the princess, but there's room for advanced play in speed-running levels, collecting star coins, and, ultimately, tackling the legendary Rainbow Road. It can be a challenging game if you elect it to be, but it's accessible to a wide range of skill levels. The story is a compulsory component devoid of originality--unless Mario's not only missing but actually dead--and the lack of new power-ups or themes is disappointing, but underneath it all is a positively twisted take on the Mario Bros. formula, and it's an excellent add-on to New Super Mario Bros U.''"

|8/10
|align="left"|"''New Super Luigi U is a terrific title for capable platform gamers, with intense and exciting bursts of momentum to put those thumbs to the test. What that does do, however, is make multiplayer even more awkward than before, and possibly puts the title beyond the reach of less experienced gamers, even with the indestructible Nabbit. The sense of the old is thankfully tempered by a fresh feel and clever level design, however, and even if the adventure won't last long for those without completionist instincts, it's fun while it lasts.''"

*''[[New Super Mario Bros. Wii]]'': [[Frozen Fuzzies]]'s gimmick of having to ride [[Big Fuzzy|Big Fuzzies]] frozen using the [[Penguin Suit]] is based on the setup needed to collect the third [[Star Coin]] in [[World 9-5 (New Super Mario Bros. Wii)|World 9-5]].
*''[[Luigi's Mansion: Dark Moon]]'': The Luigi sighting in [[Vanishing Ghost House]] is based on Luigi and [[King Boo]]'s artwork from this game.

*[[Super Mario Maker (disambiguation)|''Super Mario Maker'' series]]: The main terrain of the [[Waddlewing Warning!]] and [[Piranha Gardens]] levels appears as one of alternate designs for semisolid platforms in ''New Super Mario Bros. U''-style ground levels. In ''[[Super Mario Maker 2]]'', the snowmen from some of [[Frosted Glacier]]'s levels, albeit much smaller, appear as a cosmetic feature in ''New Super Mario Bros. U''-style snow levels. Additionally, one of alternate designs for semisolid platforms in the forest levels, similarly to the ground theme, is based on the main terrain of the levels [[Sumo Bro Bridge]] and [[Wiggler Floodlands]].

*Even though [[Nabbit]] helps Luigi in multiplayer mode, Nabbit still steals items from the [[Toad House]]s, and the players will have to catch him. It will not work when Nabbit is playing in Co-op mode, and in single-player mode if the player does the trick to play as Nabbit in the level where Nabbit went, the player will still continue playing as Luigi.
*An in-game time unit in ''New Super Luigi U'' is 1 second, while in ''[[New Super Mario Bros. U]]'', an in-game time unit lasts only 0.75 seconds.
*''New Super Luigi U'' is the only game in which Luigi appears, but [[Mario]] does not. However, Mario is referenced in the game in three ways; in the intro, in which [[Mario Cap|his hat]] is on the table, in the level [[Broozers and Barrels]], which features a Mario-based snowman at the beginning, and on the [[Luigi Block]], which has Mario's [[emblem]] on it.  
*US and Canada Club Nintendo members who purchased ''New Super Luigi U'' from the Nintendo eShop by August 1, 2013 and completed the surveys within four weeks after downloading could receive double the amount of coins (for a total of 40 coins) compared to the original amount (20 coins).
