Pikmin: Dimensional Breach is a Pikmin fan game made by user WorldBornDead. It takes place some years after the events of Hey! Pikmin, but before most other fan games. It also takes place in an alternative timeline from Pikmin Forever in which Louie was successfully rescued before he could become Loucap.

Intro

Olimar is taking his kids, Sagittarius and Libra, out for their 16th birthday on a trip through the stars aboard the SS Dolphin II as a present. Louie and Shacho, the President of Hocotate Freight, have decided to come along to help Olimar keep the kids out of trouble. As they are passing PNF-404, a shadowy figure watches them from a cliff below. As the Dolphin II flies overhead, the figure launches a bolt of purple lightning from his fingertip, smiting the ship in its Chronos Reactor. The figure gloats from his clifftop perch as the Dolphin crash-lands on the surface of the planet, its 30 Ship Parts and one million Pokos scattering across the planet surface. Just then, he notices something off in the distance, the SS Drake coming into the planet on a supply run, manned by the three Koppaite explorers. Before the figure can reach out to blast the Drake out of the sky, though, he is distracted by the appearance of strange rifts opening up where the Ship Parts and Pokos landed. Aboard the SS Drake, Charlie notices that Olimar and his friends are stranded, and so he directs Alph to land in the Impact Site to help them. Olimar explains the situation and points out that, while the Ship Parts can easily be recovered, the Pokos are likely destroyed. Louie cheers him up by pointing out that the planet still likely has enough treasure to recover the lost money, and so our eight heroes set out on a great adventure.

Gameplay

Gameplay is pretty much identical to Pikmin 3, but with eight Captains instead of just three. The objective in the end is not only to defeat the final boss while collecting as much Fruit as possible, but also to collect Ship Parts to repair the Dolphin II and Treasure to restore Olimar's life's savings.

Returning Pikmin

Red Pikmin -- Fireproof Pikmin with a 1.5X attack strength modifier. They can now pick up Embers and use them to burn flammable objects.
Blue Pikmin -- Aquatic Pikmin that can now carry water in their "bellies" and use it to put out fires. A Blue Pikmin saddled with water also has the weight of 2 regular Pikmin; this makes them more useful in weight puzzles but reduces the height and distance they can be thrown.
Yellow Pikmin -- Shockproof Pikmin that have half a Pikmin's worth of weight. They can be thrown higher and farther, but two Yellow Pikmin are required to have the same effect on a weight-affected object as one normal Pikmin. Yellow Pikmin have lost their enhanced digging speed from Pikmin 3, but they retain their ability to tear down Electric Gates and conduct electrical currents.
Purple Pikmin -- These Pikmin have a 1.5X attack strength modifier and ten times the physical strength and weight of normal Pikmin. Purple Pikmin may be much slower than most Pikmin with the shortest height and distance to their throwing arc, but they land with a resounding thud, stunning enemies in the area. Purple Pikmin are also the only kind that can anchor Wraiths in this dimension.
White Pikmin -- Small, swift Pikmin that have 1/10th the weight of normal Pikmin. They have amazing height and distance to their throwing arc, but they are practically useless for weighing things down. White Pikmin are also immune to Poison and are themselves toxic; despite having a 0.5X attack modifier, White Pikmin deal a "damage over time" effect to enemies, and they deal heavy damage if eaten.
Red Bulbmin -- A parasitic Pikmin that has taken over the body of a juvenile Red Bulborb. Unlike normal Pikmin, Red Bulbmin cannot be reproduced by Onions; they either have to be found naturally in caves or "cultivated" using Green Pikmin. Thanks to the Bulborb's anatomy, they are immune to Fire, Poison, Drowning, and Electricity. As they have no Onion, they have to be stored in the SS Drake. They can now be taken out of caves like any normal Pikmin.
Rock Pikmin -- Gray Pikmin with a rough stony shell. They can't latch onto enemies like normal Pikmin can, but they have a 3.0X attack strength modifier on impact, are immune to crushing and stabbing, and can smash through glass and crystal objects.
Winged Pikmin -- Pink Pikmin with wings. They may have a 0.75X attack modifier, but they can fly over most hazards and are incredibly mobile when fighting airborn enemies. Their flight ability allows them to pull Flukeweed stalks.

New Pikmin

Black Pikmin -- These Pikmin have glossy skin that makes them immune to Sticky. They also have the ability to detect and destroy Illusions.
Snow Bulbmin -- A parasitic Pikmin that has taken over the body of a juvenile Hairy Bulborb. Unlike normal Pikmin, Snow Bulbmin cannot be reproduced by Onions; they either have to be found naturally in caves or "cultivated" using Green Pikmin.

The Mothership

About seven days after finding all 11 normal Onions, Alph will get a strange transmission, which he assumes is from Olimar. He tries to reply, but it turns out that the Onion sent the transmission, and the Drake is promptly absorbed into it, causing the three Koppaites to black out. When Alph comes to, he discovers that the inner wall of the Drake is studded with pods containing countless sleeping Pikmin and Bulbmin, a strange organic construct (implied to be the Onion's organs) is on the wall opposite to the control panels, and he and his allies have become Koppaite-Pikmin hybrids, similar to Pikmar or Loucap. While he and Charlie are mortified by this change, Brittany doesn't mind, and in fact is happy that she can "finally try on that gift from the last party." After this cutscene, the SS Drake and Onion will have fused into one, further simplifying the storage and exchange of Pikmin and Bulbmin (although it does not make Bulbmin as renewable as other Pikmin types). This strange ship will have the Onion's three legs extending from the Drake's legs, a rocket booster/Tractor beam hybrid similar to that found on the Onion, walls swirling with the colors of the Onions (including the secret Wraith Onion if found) and the steel of the Drake's plating, an enlarged version of the Onion's flower-propeller on top alongside the Drake's antennae, and four windows along the sides, connected by the Onion's trademark triangle design. In addition, Alph, Brittany, and Charlie will have turned into Pikmin, but this is purely a cosmetic change; they are immune to all hazards that the other Captains are immune to thanks to the transformation incorporating their life-support tech into their bodies; in addition, the ending implies that they can still breathe Koppai's air despite its lower oxygen content.

Trivia

The Mothership is inspired by one of Charlie's concerns in Pikmin 3: That the Onion could grow big enough to absorb the SS Drake. Even despite turning into Pikmin, the Koppaites retain their original personalities, in contrast to Louie losing his personality when he became Loucap.
This game, along with a couple of others, marks Nintendo's debut on the modern PC.
Although the series has dabbled in the supernatural before, this game is the first to take a blatantly paranormal approach to its plot, with a wizard being the main antagonist and an army of Wraiths and portals to other dimensions being common threats.
This game is one of the few Nintendo games outside of the Metal Gear Solid series or the Metroid series to have a rating of T or higher, mainly because of Derrick's behavior as expressed in his notes.
