History Videogame / CthulhuMythosTheSleepingGirlOfTheMiasmaSea

* DifficultySpike: Losing a character means losing valuable item slots and access to their unique skills. Also, as you go into the Laboratory, enemies seem to have more defense, as you'll notice you do less damage to them than you could to enemies back in the mansion levels.

* AdultFear: Godo's reason for being in the mansion. [[spoiler:After the experiments wreaked havoc in the laboratory, he was forced to leave his daughter, Sakura, for dead. He came back hoping to find any remaining traces of her and he still feels guilty about abandoning her.]]

* AbnormalAmmo: You can occasionally find silver ammunition for guns and crossbows that will let you use those weapons against specters.

!!''Cthulhu Mythos RPG -The Sleeping Girl Of The Miasma Sea'' provides examples of the following tropes:

* AbusiveParents: Sure, volunteer your daughter for an experiment that wants to establish risky contact with other worlds. [[SarcasmMode Nothing could possibly go wrong with that, Godo]]. Never mind that even before that, he was rather neglectful of Sakura as well, choosing to absorb himself in research after his wife died. [[spoiler: The true ending has him make up for his misdeeds and from what the player can tell, he redeems himself as a father]].

* AdultFear: Godo's reason for being in the mansion. [[spoiler: After the experiments wreaked havoc in the laboratory, he was forced to leave his daughter, Sakura, for dead. He came back hoping to find any remaining traces of her and he still feels guilty about abandoning her.]]

* ApologisesALot: Godo. He apologizes to the protagonist if they choose to leave the mansion early, he apologizes to everyone for getting them involved with the mystery of the mansion [[spoiler:after he finally tells them the truth]], and he apologizes to Sakura if he manages to find her. [[spoiler: Considering how much at fault he is for her predicament, never mind his role in the secret research the scientists there were involved with, he has a lot to be sorry about.]]
* ArbitraryHeadcountLimit: There are six playable characters but you only get access to three at the most, and you only get one chance to decide who will be on your team. The other characters handle other objectives on the opposite side of the mansion, which comes in handy towards the end of the plot. [[spoiler: They also fight against the Chaos Beast in their own final battle while you and your characters handle the Outer God.]]

* ChainsawGood: The Chainsaw is one of the strongest weapons in the game and in the hands of a Strength-based character, they can wreck anything, even [[spoiler: the Outer God]].

* DeathOfAChild: [[spoiler: At least one case. The victim who had the Wristwatch you find was a middle school student who ran in the mansion after being bullied at school. He didn't last long.]]

* DrivenToSuicide: [[spoiler: This can happen to Godo if you beat the game without rescuing Sakura.]]
* EarlyGameHell: Much like with VideoGame/SweetHome, the combination of limited supplies and random encounters can make the game rather difficult from the beginning. And unlike with the former, characters here are not guaranteed to attack first, as their Dexterity and Size attributes determine that. Thankfully, NewGamePlus allows players to start the game over while carrying their levels over from previous playthroughs, making the early game much easier.

* EscapeSequence: The first time you access the Laboratory levels, you will be confronted with the creepy girl who shifts into the Chaos Beast. Both your party members advise you to run, prompting a chase sequence that only ends if you successfully find a place to hide from the boss. You always get the first move to run away, but the longer you take to avoid her, the more damage you take to your sanity, as it takes a hit every single time you encounter her. You will then encounter her at random as you're trying to explore the laboratory. The monster eventually makes its final appearance at the end of the game and is dealt with by the other team as the player team deals with [[spoiler: the Outer God]].

** Phlegmatic: The protagonist gets to make decisions on who they to travel with, what objectives they will be focusing on, and this responsibility is actually acknowledged in game by the other characters because they realize you're trustworthy and dependable. This also helps in the final battle because [[spoiler: if your party members make it to the battle against the Outer God, their trust in you helps you all regain some sanity before you start the encounter.]]

* FragileSpeedster: Both Daiki and Yurie qualify. Daiki is the fastest character in the group and is the only one who gets Double Attack, giving him a chance to deal attacks to an enemy [[ExactlyWhatItSaysOnTheTin twice in a row]]. Yurie is almost as fast but is more focused in Strength. However, in a Mythos game, where the worse threats are to your sanity and not necessarily always your health, they are both fragile in that regard. Especially Yurie.
* GenderEqualEnsemble: Enforced depending on the gender of the protagonist via [[spoiler: Mamoru.]] Whatever the protagonist is, [[spoiler: Mamoru]] will be the opposite gender, allowing for a gender-equal cast.
* GoMadFromTheRevelation: Both minor and extreme examples exist, though all are reversible. Unless everyone is insane, then it's a [[GameOver Game Over.]]

* HealingHerb: As per Franchise/ResidentEvil. You can even mix them if you have the right skills. Sachi can do this by default.
* HeartsAreHealth: The game features both normal HP in the form of numbers and additional HP via green hearts in a character's display. They act as [[OneUp One Ups]] where if a character takes enough damage where one is consumed, they won't be reduced to zero. These can't be recovered with conventional means, however, and specifically requires Medicine Sprays to bring them back.
* IChooseToStay A rather dark example. The protagonist can choose to leave while other characters may choose to stay to help Godo. [[spoiler: This gives a bad ending, in that they all disappear, the mansion is designated to be torn down, but several construction workers go missing or die accidental deaths in the process.]]

* InfinityPlusOneSword: This is still a JRPG-inspired game, so this exists in the form of "Annagi," or "One That Cuts the Darkness. It has ATK +11 and can be used to deal damage against ghosts, but can only be accessed late game and even then, only characters with high Mind can wield it. The Brass Knuckles are basically this for Yurie, and there's also the Chainsaw. A katana that players can get after acquiring the True Ending can also be this in the hands of a high Dexterity-based character like Daiki.

* JigsawPuzzlePlot: What starts off as a basic haunted mansion story eventually involves secret experiments in a lab, government cover-ups, serial killers, the sixth sense...[[ArsonMurderAndJaywalking and Feng Shui.]] You can learn more about some of these things from notes and items you find around the place.
* LazyBackup: Subverted: While you never get to play with the other half of the party, and they even sit out for most of the rest of the adventure after you all make it to the Laboratory, they do help advance the plot with their actions. They may hold the other keycard you need to access the final room and [[spoiler: they fight [[BackToBackBadasses against the Chaos Beast as you fight against the Outer God.]] And they will always survive their encounter, no matter who is in it.]]
* LockAndKeyPuzzle: One of your first objectives are to find the keys to help you escape the Manor while the latter half of the game has you using the Annex keys the other team found and the Black Key Card to get around the laboratory.

* MagicIsEvil: Subverted. Much like Call of Cthulhu RPG, characters can eventually access magic spells through spellbooks they find in the mansion and its grounds. However, it's implied that the magic you do access came at a great cost to...someone who used to work there. In fact, the book you find explaining magic in the game is found at the same site where a serial killer murdered several women, with a bloody magic circle located right in front of its bookshelf. Mechanically, spells cost MP to use, not sanity. But casting magic beyond one's MP capacity will drop that character into a coma they cannot recover from unless they use a magic stone to restore their points. And since those items are extremely [[PowerAtAPrice rare...]]
* MrExposition: Godo. Makes sense considering [[spoiler: he used to be a researcher who worked in the laboratory there.]]
* MultipleEndings: There are five multiple endings in the game and each one is dependent on your choices, such as leaving the mansion before solving the mystery, whether you save Sakura or not, and if people are alive.

* NightmareFetishist: While most of the other characters freak out whenever they encounter monsters like the Chaos Beast [[spoiler: or the Outer God]], Mamoru notes how "fascinating" or "amazing" they are, making them this. They may have even been in the mansion exploring some time before the main cast entered, visiting specifically to share what they learned on social media sites dedicated to everything occult called the "OccuBoards."
* NintendoHard: Even the normal difficulty can be difficult for first-time players due to the sparse amount of healing resources and random encounters they have to deal with. Eventually, it becomes manageable, especially if the player takes advantage of the NewGamePlus feature to leave the mansion early and carry over their levels for a better run. Of course, if you beat the game, there's hard mode and that...[[HarderThanHard well...]]
* OhCrap: Several times. Daiki with the giant roach, Yurie with ghosts, and the first time they all see the ghost girl's [[ImplacableMan true form.]]
* PapaWolf: Godo is this [[spoiler: along with [[TheAtoner The Atoner]] because Sakura is only in danger because of him and his work]].

* PluckyGirl Yurie and Sachi both qualify.
* PreexistingEncounters: Really only [[spoiler: the Outer God]] and the Mother Plant, the latter of which is optional.

* SanityMeter: Being a Franchise/CthulhuMythos game, it's bound to have one. Characters have sanity meters of varying values, depending on stats such as Intelligence, Mind, and Education. Generally speaking, caster-type characters like Mamoru and Sachi have high sanity while fighter-type characters like Daiki and Yurie have either average or below-average sanity. Godo, [[spoiler: being a researcher]], is somewhere between the two and has decent sanity. Characters who take too much damage to their sanity will become insane but thankfully, this isn't permanent, as skills like Mental Recovery or even just giving a character a drink can help restore them to normal.
* ScrewThisImOuttaHere: The player can choose to do this any time after they get the manor keys. [[spoiler:The final boss also does this after you deal enough damage to it. Mamoru even states that they didn't defeat the Outer God, it was more like they simply left them, making your victory more of a [[VictoryByEndurance Victory By Endurance]] than a straight-up win.]]

* TrueCompanions: Relying on your companions' unique skills and keeping them alive is vital to complete the game. If they all make it to the final battle, [[spoiler: their sanity will recover before facing the Outer God because]] they choose to trust in each other. In the True Ending, one of the first things they decide to do is share contact info with Godo, Mamoru, and even Sakura, and in the final photo, [[spoiler: the entire cast is there to see Sakura's graduation]].

* WhatTheHellHero: The protagonist can do this with Godo after the latter reveals [[spoiler:the truth behind the laboratory and his role with it.]]

* StandardStatusEffects: Characters will have to worry about things like Bleeding and Poison, in addition to sanity loss.

* FinalDeath: This can happen to any character who takes too much HP damage.

* InfantImmortality: [[spoiler: Averted in at least one case. The victim who had the Wristwatch you find was a middle school student who ran in the mansion after being bullied at school. He didn't last long.]]

* AllPowerfulBystander By the final boss' own admission, they are this. They could simply resolve the issues plaguing the mansion [[spoiler: especially since they're the one specifically responsible for the miasma.]] They simply choose not to.

* AnyoneCanDie: If any of your characters take damage again after their HP enters zero, they're dead, and there are no items in the game that can revive dead characters. Interestingly, the only characters who can possibly die are those the players control. The other three you don't select will always survive the events of the mansion [[spoiler: unless you fail to save Sakura, in which case Godo [[DrivenToSuicide kills himself]], or if the player's party falls to the Outer God, in which case it's implied everyone died and monsters then took their advantage to invade the world.]]

''Cthulhu Mythos RPG - The Sleeping Girl Of The Miasma Sea'' is a Survival Horror RPG based on the Franchise/CthulhuMythos. You play with a custom character and their friends who enter an abandoned mansion for a "test of courage." They soon find they're not alone and have to confront everything from enlarged insects and ghosts, to Lovecraftian monsters like zombies and Yuggothians. To make matters worse, they encounter a creepy girl who chases them around the place after transforming into a horrible monster. With their companions, it's the player's job to overcome the terror of the mansion and unravel its secrets, all while relying on what few resources they can find to maintain their health and sanity.


----

* [[WhyDidItHaveToBeSnakes Why Did It Have To Be Ghosts?]]: Yurie definitely has this. Like with Daiki and insects, her phobia has the upside of letting her do bonus damage to ghosts. However, she still takes extra sanity damage whenever she sees one.

* RecruitTeenagersWithAttitude: Discussed. Godo, Mamoru, and the kids talk about getting police and the government involved, but since [[PoliceAreUseless police are not typically proactive, much less when eldritch beings are involved]], and the government is involved in a [[GovernmentConspiracy major cover-up]] and believes the miasma has already been dealt with, it's up to the six of them alone to handle the threat. Godo even regrets asking for their help and even recommends they leave, but if they insist, he relents. Mamoru offers to help the kids, particularly they're still underage and have yet decided to take on a great responsibility.

* WhatTheHellHero: The protagonist can do this with Godo after the latter reveals [[the truth behind the laboratory and his role with it.]]

* Unwinnable: A distinct possibility that even in-game help books anticipate. Making use of the NewGamePlus feature allows players who can't win the final boss due to lack of strength or healing items to go to the beginning with their accrued levels, make it to the end, and try again to have a better shot.

* TrueCompanions: Relying on your companions' unique skills and keeping them alive is vital to complete the game. If they all make it to the final battle, [[spoiler: their sanity will recover before facing the Outer God]] because they are putting their trust in each other.

* Posthumous Character: Godo's wife, Sumire, the owners of the [[ApocalypticLog Apocalyptic Logs]], and technically the undead monsters you encounter.
