Pikmin: Dusk and Dawn/Upgrades

Upgrades are collectible and unlockable perks in Pikmin: Dusk and Dawn that benefit leaders and Pikmin alike. They can be either bought with Luminum, Solium, and Pokos, or found as treasure. Some major upgrades either require other upgrades or a specific treasure. Upgrades transfer to New Game+ playthroughs, as some important upgrades can only be accessed near the end of the game.
