Editing 2-Player Battle

'''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|Red]] 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.

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 right away. 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. Leaders cannot [[punch]] each other or opposing Pikmin, nor can they interact with the enemy's Pikmin, besides being attacked by them. These Pikmin pummels prevent the victim from throwing, whistling, rolling the roulette wheel, and using either spray. Attacking Pikmin cause no damage to the leader, but do trigger invincibility frames, resulting in [[enemy]] attacks dealing no damage on occasion.

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.

*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 Pikmin in-fighting or otherwise.

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:

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.

Have your Pikmin army 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}}.

[[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.

==Stage generation and layouts==

{{image|Add maps of each layout}}

Unlike [[Story Mode]] and [[Challenge Mode (Pikmin 2)|Challenge Mode]] caves, which [[Pikmin 2 cave generation|generate sublevels]] 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 random sublevel generation logic is still in effect during the generation of 2-Player Battle stages.

 

The game begins by loading the list of necessary cave units for the stage, in the same format as the lists used in Story Mode and Challenge Mode. Then, the game places whatever manually-specified units exist in their right places, if any. Finally, it starts filing the stage randomly just like in the other game modes, until the stage is completely generated without any issues.

 

Different stages have different generation modes and different layouts. [[Dim Labyrinth]] has no predefined layout and instead always generates the stage randomly like other caves. [[Carpet Plain]] has 2 predefined layouts. [[Brawl Yard]] has a 20% chance of generating the stage randomly, and an 80% chance of using one of its 3 layouts. All other stages have 3 predefined layouts and nothing else.

 

When the game loads the stage, it starts by deciding if it will generate it randomly or by using the fixed layouts, and then if applicable, chooses at random one of the existing layouts. The 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}} on the GameCube, or {{button|wii|pad}} on the Wii, 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 game will load the variant determined by the direction pressed.

*{{button|gc|cl|wii|padl}} '''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.

By holding left, the level is forced to generate at [[Randomization|random]], even for stages that don't support it. This generation does not take into account balance, meaning that it is unlikely that a stage will be symmetrical, and more often than not, the [[Onion]]s are placed in bizarre and inappropriate locations. Because of the secrecy of this feature, as well as the potential for gameplay balance problems that arise with the "left" variant, it is likely that this was actually a debugging tool in the game during development, but never removed for the final release.

*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.
