'''2-Player Battle''' ({{j|２Ｐバトル|Tsū Pi Batoru|2P Battle}}) is a game mode in ''[[Pikmin 2]]''. It involves, as the name implies, two players, who control [[Captain Olimar]] and [[Louie]], with a party of up to 50 [[Red Pikmin]] or [[Blue Pikmin]], respectively. Each player can start the match with a multiple of 5 [[Pikmin family|Pikmin]] between 5 and 50, and cannot exceed 50 total Pikmin on the battlefield at any time. 2-Player Battle mode takes place in underground areas, their layouts [[Randomness|random]]ly picked from a list. Each player has a related [[Onion]], near which a similarly-colored marble lies at the start of the game. There are four [[#Ways to win|ways to win]] and ten differently-themed areas to play on, ranging in difficulty. A number of [[Pellet Posy|Pellet Posies]] will spawn next to both Onions on all maps, and a group of [[Female Sheargrub]]s will spawn nearby on a select few maps, allowing both players to bolster their numbers.

Returning a [[Cupid's Grenade|cherry]] to an Onion will allow a spin of the [[#Roulette wheel|roulette wheel]]. To make things even, [[Blue Pikmin]] are given the strength of [[Red Pikmin]], and bodies of water are absent. However, both types are still immune to their respective elements. If a Pikmin dies from an attack caused by the other team's Pikmin, it will be transformed into a seed, which is expelled from the Onion after a small delay. Regardless, if said Pikmin is the last one alive, a [[Pikmin extinction]] will still occur. [[Ultra-bitter spray]]s, when used against the opponent's Pikmin, will burrow them, and revert them to [[Maturity|leaf state]]. However, they'll pop out of the ground automatically after 10 seconds. Other combat details can be found [[Combat#Player opponents|here]].

On all maps, unearthing a [[Crystallized Telekinesis|yellow marble]] with occasionally spawn 1-5 [[Shearwig]]s where the marble is unearthed. Note that this chance is based off how many yellow marbles have been collected and the proximity of any uncollected yellow marbles, where equal players will have a 20% chance to spawn 1-3 Shearwigs, a player at an advantage will have at most an 80% chance to spawn 3-5 Shearwigs, and a player at a disadvantage will have at least a 1% chance to spawn 1-3 Shearwigs. The player which is determined to be unearthing a marble is decided by whose Pikmin makes up a majority on the marble.

Unlike other [[loading]] screens in the game, 2-Player Battle stage loading screens will contain a [[Loading#Tip|random tip]].

== Ways to win ==
There are four ways to score a victory over the opponent:
* Taking 4 yellow [[Crystallized Telekinesis|yellow marbles]] to the Onion. Note that there are only 7 in total, making it so that only one player can do so.
* Taking the opponent's marble to the Onion. Note that Pikmin cannot carry their own marble.
* The opponent suffers a [[Pikmin extinction]]. Note that this can happen from [[Combat#Player opponents|Pikmin in-fighting]], but because Pikmin that die this way respawn at the Onion after a delay, the extinction needs to happen during this delay in order for the player's count to reach 0.
* The opponent's leader is down.

== Arenas ==
The players can choose one of ten maps. Every level uses [[Music in Pikmin 2#Battle theme|the same music]]. Unlike the [[cave]]s in story mode, these are not generated randomly, with the exception of the [[Dim Labyrinth]] and rarely [[Brawl Yard]]. Instead, one of three (two for the [[Carpet Plain]]) fixed layouts is chosen.

== Items ==
The roulette wheel can be accessed when a player finds a cherry and a Pikmin successfully returns it to the Onion. Cherries in this mode spawn [[Randomness|random]]ly, and only one Pikmin is needed to carry one. When the roulette finishes spinning (automatically), it'll randomly land on an item, which the player can use at any moment by pressing {{button|gc|y|wii|-|switch|y}}.

If more cherries are collected before the player uses the current item, they'll be added to a queue, represented on the top-right corner with red dots, for a maximum of 5 items waiting to be used. Pressing {{button|gc|y|wii|-|switch|y}} will use the item and instantly make the roulette spin for the next one. The spinning takes around three seconds, which stops the player from using an item right after another.

The player will have access to 12 different items that benefit them, disadvantage the opponent or both, listed below, and sorted by the order in which they're placed on the roulette:
{|class="wikitable"
!Icon !! Power !! Description
|-
|[[File:Roulette Wheel 5.png]] || +5 Sprouts || Grants the player five Pikmin sprouts, if they have less than 50.
|-
|[[File:Roulette Wheel 10.png]] || +10 Sprouts || Just like the previous, but ten sprouts.
|-
|[[File:Roulette Wheel flower.png]] || Flower || Makes all of the player's Pikmin that are not planted in the ground [[Maturity|bloom]] into flowers.
|-
|[[File:Roulette Wheel ghost.png]] || Ghost || Makes the player's leader and Pikmin become invisible to the opponent for a limited amount of time. The opponent can still see the dust from the player's footsteps, the leader's whistle, and, if their Pikmin are affected by the ultra-spicy spray, the glowing circles on their heads. Additionally, the opponent's Pikmin can still see everything, and the leader and Pikmin are fully visible on the collecting player's portion of the screen.
|-
|[[File:Roulette Wheel ultra-bitter spray.png]] || [[Ultra-bitter spray]] || Grants one dose of ultra-bitter spray.
|-
|[[File:Roulette Wheel ultra-spicy spray.png]] || [[Ultra-spicy spray]] || Grants one dose of ultra-spicy spray.
|-
|[[File:Roulette Wheel marble.png]] || [[Crystallized Emotions Series|Marble]] return || Makes the player's marble, if above ground, bounce all the way back to the Onion, regardless of distance. Any opposing Pikmin carrying the marble will be knocked down.
|-
|[[File:Roulette Wheel Withering Blowhog.png]] || [[Withering Blowhog]] || Makes a Withering Blowhog appear near the opponent's Onion.
|-
|[[File:Roulette Wheel Swooping Snitchbug.png]] || [[Swooping Snitchbug]] || Makes a Swooping Snitchbug appear near the opponent's Onion.
|-
|[[File:Roulette Wheel boulder.png]] || [[Hazard#Boulders|Boulders]] || Makes several boulders drop near the opponent.
|-

|-
|[[File:Roulette Wheel Blowhogs.png]] || [[Fiery Blowhog|Fiery]]/[[Watery Blowhog]] || Makes a Blowhog appear near the opponent's Onion. If the opponent is [[Louie]], a Fiery Blowhog will appear. If the opponent is [[Olimar]], a Watery Blowhog appears instead.
|}

Enemies created upon a spin of the Roulette Wheel disappear completely on defeat, meaning their bodies cannot be returned to either Onion. They automatically die after 50 seconds have passed.

== Strategies ==
[[File:Pm2 2playermodes.png|thumb|Head to head two player action.]]
{{guide}}
These are basic strategies. The strategies' nature allows them to be combined and expanded upon freely, to maximize their efficiency.

=== Wasting the opponent's sprays ===
Sprays are an essential part of battle mode, as they can turn the tides in a Pikmin vs. Pikmin situation easily. Using a small squad, attacking the enemy might get the other player to use sprays prematurely. This can be repeated with the rest of the Pikmin. Another strategy is to send small forces to attack your opponent repeatedly, this should drain their spice deposits. Afterwards, rush the opponent with all of your troops. Bitter spray their Pikmin, then spicy spray yours. Afterwards steal their marble with a few Pikmin. Escort the marble with about 1/4 of your troops, and have the rest engage with your opponent's troops, allowing you to distract your enemy. This is very effective at War Path.

=== Collecting marbles ===
With a small squad, the player can run to the opponent's base and steal the marble, assuming the other player is not there with a larger squad. Should the other player come to defend the marble, running up to them with the rest of the Pikmin can distract the enemy Pikmin from getting to the marble that is being carried away. Creatures can also be led to the enemy base as means of distraction or to kill [[idle]] Pikmin.

For yellow marbles, if the other player is likely to stop marbles from being brought back, it is advisable to collect ones that are on opposite side of each other, as it will force the other player to decide between them.

=== Guard Pikmin ===
Leave about 3-5 Pikmin at your marble to act as an alert system. When your numbers start to change, get back to base. They can also be left in crucial bottleneck passages.

=== Cherry siege ===
This one often requires a bit of luck as it relies almost entirely on random generation. The cherries that allow you to use a roulette spin will oftentimes drop steadily in the same area of the arena over time (usually in one of the alcoves.) Take note of where cherries seem to drop more during the match, then keep Pikmin in that area to quickly transport them back to the Onion. You can actually hold up to five spins at a time. Use the spins strategically or all at once in hopes that you'll drop lots of enemies and obstacles to keep your opponent busy. Large-scale distractions like this can help you steal marbles without them noticing or even a [[Pikmin extinction]] if your opponent is careless enough.

=== Pikmin rush ===
Focus on increasing your army above everything else. If you're faster than your opponent, you can gather quite a number advantage. Then, go for the enemy with almost all your Pikmin. You can even let one or two Pikmin carry the opponent's marble while they're busy with the battle.

=== Attack the leader ===
Have your Pikmin army [[Combat#Player opponents|attack the opponent's leader]]. Pikmin attacks will never damage the leader, but they will distract the player. Meanwhile, you can focus on getting the marble. If you get attacked by the opposing team's Pikmin, shake them off by quickly rotating {{button|gc|stick|wii|stick|switch|lstick}}.

An attacked leader can use Pikmin from his team to help shake the aggressive Pikmin off. Keep this in mind when you plan an attack like this, and prepare your Pikmin numbers accordingly.

=== Handling idle Pikmin ===
[[Idle]] Pikmin on the opposing team can be dispatched in a number of ways. You can try luring the Pikmin towards a [[hazard]] or [[enemy]], or spawn your own with the roulette wheel. On a stage with them, you can even throw bomb-rocks at Pikmin to easily wipe them out. As a last resort, you can use an [[ultra-bitter spray]] to get rid of Pikmin guarding a choke point. Do not use Pikmin of your own to clear these idlers out, as they'll just be reborn at the Onion.

== Player interactions ==
{{game help|p2|Describe the rules for when one player's Pikmin are carrying something, and the other player's Pikmin show up.}}
Players have a few ways of directly interacting with each other's group. For combat, see [[Combat#Player opponents|here]]. Players cannot whistle each other's Pikmin.

== Victory details ==
[[File:2-player reactions.png|thumb|80px|Facial expressions for each of the leaders.]]
The [[leader]]s' faces on the main 2-player Battle screen change depending on the current score leader. If one player is one point ahead, that player's leader will smile, and the other leader will frown. If a player is three points ahead, their leader will grin, and the other will be quite angry.
If the scores are the same for both players, both leaders will have a neutral expression.

Whenever a player has 3 marbles, their Pikmin will chant the corresponding leader's name, "''O-ri-ma!''" or "''Ru-i!''", over the latter's Japanese names, Orimā (オリマー) and Rūi (ルーイ). If both players have 3 marbles and only one remains, both Pikmin groups will still chant, over one another. Amusingly, the Pikmin will still chant if they're all burrowed underground.

Each leader has his own [[Music in Pikmin 2#Endings|victory tune]]. Though they follow the same melody, the Pikmin will call out the name of whoever won once the tune finishes. If one of the players loses through excess damage to the suit or Pikmin extinction, the themes will have a slight variation in rhythm similar to the difference in the story-mode levels. In the unlikely case of a tie, a different tune plays and both the leader's names will be called out by the Pikmin. The tune changes with each type of tie.

Excluding the variations of the Pikmin chorus, there are eight different themes that can play: one player wins, Olimar loses due to extinction, Olimar loses due to damage, Louie loses due to extinction, Louie loses due to damage, draw by simultaneous marble-collection, draw by simultaneous extinction, and draw by simultaneous damage.

== Stage generation and layouts ==
[[File:P2 Angle Maze Raging Long Legs.jpg|thumb|right|A [[Raging Long Legs]] appears exclusively in layout #3 of the [[Angle Maze]].]]
{{image|Add maps of each layout to each of the articles.}}
Unlike [[Story Mode]] and [[Challenge Mode (Pikmin 2)|Challenge Mode]] caves, which [[Pikmin 2 cave generation|generate sublevels]] solely by placing [[cave unit]]s randomly, the stages in 2-Player Battle are mostly made by placing specific units in specific spots to end up with layouts hand-made by the developers. That said, the [[Randomization|random]] sublevel generation logic is still in effect during the loading of 2-Player Battle stages.

When the game loads a stage, it starts by deciding if it will generate it entirely randomly or by using fixed layouts; in the latter's case it also chooses which of the existing layouts. It then  loads the list of necessary cave units for the stage from the game files, in the same format as the lists used in Story Mode and Challenge Mode. Then, it places whatever manually-specified units exist in their right places, if any. Finally, it starts filling the stage randomly just like in the other game modes, until the stage is completely generated without any issues (like unconnected doorways).

Different versions of the game and different stages have different generation modes and different layouts:
* In the [[Pikmin 2 (Nintendo Switch)|Nintendo Switch version]]...
** All stages are chosen to be generated randomly by default.
* In other versions...
** [[Dim Labyrinth]] has no predefined layout and instead always generates the stage randomly.
** [[Carpet Plain]] has 2 predefined layouts, with a 50% chance of either being picked.
** [[Brawl Yard]] has a 20% chance of generating the stage randomly, and an 80% chance of using one of its 3 layouts with equal odds.
** All other stages have 3 predefined layouts, with a 33.3% chance of either being picked.

The generation method and layout chosen can be manually selected by the player with an undocumented feature. To activate it, player 1 should be holding a direction on {{button|gc|c}} ([[Pikmin 2|GameCube]]), {{button|wii|pad}} ([[New Play Control! Pikmin 2|''New Play Control'']]), or {{button|switch|pad}} ([[Pikmin 2 (Nintendo Switch)|Switch]]), while the loading screen with the [[Loading#2-Player Battle|tips]] is showing up. The time at which the player starts holding does not matter, as long as it's before the loading screen appears, and the player can let go at the loading screen. The direction held controls how the stage will be generated:

* '''Up''': Layout #1.
* '''Right''': Layout #2.
* '''Down''': Layout #3.
* '''Left''': Random generation.

To know which layout number corresponds to what, please read the corresponding level's article, and check the technical information section. For the Carpet Plain, both right and down result in layout #2. Because Dim Labyrinth is always randomly generated, holding a direction has no effect there.

All stages can be generated at random, but it is clear that this was not intended for some of them. The randomization system does not take into account balance, meaning that it is unlikely that a stage will be symmetrical, and more often than not, for unintended stages, the [[Onion]]s are placed in bizarre and inappropriate locations. Because of the secrecy of the manual generation method selection feature, as well as the potential for gameplay balance problems that arise with the "left" variant, it is possible that this was actually a debugging tool in the game during development, but never removed for the final release. The reason as to why random generation is the default mode in the Nintendo Switch version is not known, and manually forcing a specific layout is recommended.

== Trivia ==
* The Angle Maze features a [[Raging Long Legs]] in one of its variations. It is the only battle map to include a [[boss]] enemy.
* Within the game's files, one can find textures for 3 unused Roulette Wheel slots: an [[Antenna Beetle]], a [[Spotty Bulbear]], and a combination of a [[Fiery Dweevil|Fiery]] and [[Hydro Dweevil]], the latter having a duplicate file with the same name, but with "_old" appended. The backgrounds' colors and lines indicate that these slots were removed before the final icon textures were cleaned up.
* In this mode, the leaders are immune to the Watery Blowhog's water-like liquid and the Fiery Blowhog's fire. In the story mode, while it is still possible to gain immunity to fire by collecting the [[Scorch Guard]], there is no upgrade allowing the leaders to be immune to the Watery Blowhog's liquid.
* In the [[GameCube]] games, the [[idle]] Pikmin at the start of a match will not have glowing stems. If they are taken in the group and then made idle again, their stems will glow like normal. This [[glitches in Pikmin 2|glitch]] was fixed in the ''[[New Play Control!]]'' versions.
* In the ''New Play Control!'' versions, at the start of a match, idle Pikmin that join a [[leader]] will first race to a point far away from the leader, and only after a second return to their rightful spot in the group. The reason for this is not known.
* [[Snow Bulborb]]s, [[Dwarf Orange Bulborb]]s, [[Breadbug]]s, [[Anode Beetle]]s, and [[Careening Dirigibug]]s can only be delivered to [[Onion]]s in this mode.
