Pikmin: Dusk and Dawn/Upgrades

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

 * Memory Album: Unlocks Boss Rush, a mode where you refight all the bosses in the game.
 * Familiar Key: Unlocks Challenge Mode, a mode where you complete caves akin to Pikmin 1 and 2, with varying objectives.
