History VideoGame / QuantumProtocol

* NintendoHard: All dungeons after the first have enemies with effects that can easily disrupt your strategies along with very tanky and tricky bosses. Even the PurposelyOverpowered Checkmate deck will struggle with these enemies if the player cannot figure out the best strategy.

* AuthorityEqualsAsskicking: Queen is the leader of Quantum and has a deck that is intentionally easier to use compared to the others, since it's already strong enough to beat all the story dungeons without having to use the deck editing system.

* ThemeDeck: All decks contain cards based around a certain theme, such as fruit, Japanese weapons, music, and chess. These cards also have effects to support other cards of the same type.

* CloneByConversion: The Black Virus card can transform the card that destroys it into a copy of itself while still having an automatic effect that regularly damages the operator. Worse yet, it voids the original card so that it cannot be accessed from the trash. The only way to destroy the virus without getting infected is to use the execution mechanic.

You play as Quantum, a hacker organization that destroys malware and fixes security problems with a card game interface. Unfortunately, the island city they're stationed in is ruled by a cyberterrorist, Omega, who is more than capable of matching them program for program. It'll take a combination of both R&D and strategic card plays in order to stop Omega's machinations.

* CityOnTheWater: The art of the city indicates that it's an island, but in the penultimate dungeon, it's revealed that the island is being balanced by a machine so it doesn't tip over, indicating that the island is artificial.

* ObliviousToLove: Leo tries to help his friend, Luke, flirt with Aurora, but Luke realizes that Aurora already has a crush on Leo. Unfortunately for Aurora, Leo only sees her a a childhood friend and is too dense to notice her feelings.

* {{Yandere}}: [[spoiler:When Kaia fixes Omega's brain computer, she encounters a wave full of cards named Queen, showing that he's obsessed with Queen.

* VillainRespect: After the Aegis dungeon, Omega criticizes Victor for skimping on security camera costs, to which Victor responds that he needed to spend money on other hardware. Victor states that he'll only bother upgrading the cameras after Omega increases his funding. Despite being on the losing end of this deal, Omega compliments Victor for manipulating the former into giving the latter more money.

* SparedButNotForgiven: [[spoiler:Although Omega is spared and allowed to join Quantum in the postgame, it's clear that the group doesn't fully trust him. Considering that he was planning to use a comet as a WMD and was willing to sacrifice Dragoons to pull it off, their distrust is understandable.]]

* SaveTheVillain: [[spoiler:After Queen defeats Omega's puzzle level, his brain computer malfunctions and nearly kills him. Queen is willing to let him die, but Idol convinces her to save him.]]

* UnwittingInstigatorOfDoom: [[spoiler:The Dragoons who crashed onto the surface did so by accident and never intended to hurt anyone. Unfortunately, this destroyed an entire country, causing Omega to become desperate to regain his land's former glory.]]

* WellIntentionedExtremist: Omega believes he needs to use powerful malware to restore his country that was destroyed by the Dragoon comet. Since his country has negligible military power, he wants to make up for that with a virus that can delete any nation's data.

* NiceJobBreakingItHero: [[spoiler:According to the dev's Discord post, Queen caused Omega to lose control of his virus when she defeated him, leading to the comet he uploaded it to going out of control too.]]
