History Main / DoubleUnlock

** ''VideoGame/AnimalCrossingNewHorizons''':

** In ''VideoGame/LikeADragonInfiniteWealth'', unlocking other jobs for the party requires leveling up Ichiban's personality and then going to the main Alo-Happy Tours location to pay for a trip that will then unlock the job.

** ''VideoGame/FinalFantasyXII'''s License Grid system. To equip a new item or learn a new ability, you must buy the item/ability from the store with Gil, then purchase the relevant License on the character's personal License Grid with LP. In another level of Double Unlock, potential Licenses are not revealed until you purchase the adjacent Licenses on the grid.

* In ''VideoGame/GrowingUp'', in order to unlock a new skill, you first have to have enough of a certain stat, which is increased by collecting resources from the Brain Map, and then you have to buy the skill with Knowledge Points. You can reduce the cost of the skill by further increasing your stat that's associated with it.

** Beating the final boss reveals the game's secret world. In the original UsefulNotes/{{Wii}} version, it only has one level, but in the UsefulNotes/Nintendo3DS version, it has nine levels (with the new ones being examples of AllTheWorldsAreAStage, as they're thematically based on the regular worlds). Regardless, if you want to play it, you need to get the eight orbs from the NintendoHard hidden temple levels. Which ''themselves'' require that you get all the KONG letters in the other levels. This also applies for ''[[VideoGame/DonkeyKongCountryTropicalFreeze Tropical Freeze]]'' with the extra world Secret Seclusion.

* The [[UsefulNotes/SegaDreamcast Dreamcast]] port of ''VideoGame/SNKVsCapcom'' had quite a few double unlocks. Most egregious: To unlock the secret characters [[VideoGame/SamuraiShodown Nakoruru]] and [[VideoGame/{{Darkstalkers}} Morrigan]], you had to first buy all of the [[PaletteSwap extra colors]] of the characters from the respective companies. This allowed you to buy Nakoruru's (for SNK) and Morrigan's (for Capcom) "shadows", which meant that you could fight them in the middle of a tournament if your scores were high enough. Only after defeating both of them in the aforementioned manner and after buying the EX versions of their respective companies' characters could you buy them and unlock them for play. Playing as the game's TrueFinalBoss, [[Franchise/StreetFighter Akuma]], required a repeat of the process -- buying Morrigan and Nakoruru, unlocking Akuma's shadow, getting to Akuma and winning against him in the final fight, and finally buying him. For those without the [[UsefulNotes/NeoGeo Neo-Geo Pocket]] and a copy of ''VideoGame/SNKVsCapcomMatchOfTheMillennium'', these requirements were onerous and grinding indeed.

* The [[UsefulNotes/NintendoEntertainmentSystem Famicom]] port of ''VideoGame/YsIAncientYsVanishedOmen'' has a cluster of unlocks to enter the Abandoned Mine. First you need to use the teleportation statues in the overworld to find Frea the water guardian, then fetch the Staff of Sarana so she can power it up, then use it to move a tree out of the way. Then there's one more kicker; the inital mine entrance is a fake; to enter the real mine, you need to solve a puzzle back in Minea according to the instructions in the fake mine. Other versions of the game also have their share of double and multiple unlocks, for example, to reach the last part of the Shrine, you need the Mask of Eyes, which is in a locked chest opened with the Treasure Box Key, which, at least in some versions, you have to obtain from Feena, whose cell is unlocked with the Prison Key. Then after that, you have to find two more keys to unlock the boss room.

* Prior to the June 2014 Xbox Live update, accessing third party services (e.g. Creator/{{Netflix}}, Creator/{{Hulu}}, etc.) on UsefulNotes/Xbox360 or UsefulNotes/XboxOne required both a paid account to the service in question ''and'' an Xbox Live Gold subscription.

* ''VideoGame/FZero GX'' also requires purchasing things in a shop after you have 'unlocked' them. Unlike other examples, currency is [[MoneyForNothing absurdly easy to come by]]. Especially if you are fortunate enough to live near an arcade with ''F-Zero AX''--take your memory card to the machine and play a few rounds. Guaranteed currency for finishing a race.

** The ''Heart of Thorns'' expansion regions can only be accessed after completing several chapters from Season 2.
