History YMMV / FaithTheUnholyTrinity

** [[spoiler:Gary]] [[CallingYourAttacks shouting]] "RAIN OF SPIDERS!" and [[ExactlyWhatItSaysOnTheTin summoning a dozen of giant spiders from the sky]]. It's so sudden and silly it makes the fight impossible to take seriously, especially if he uses it multiple times in a row.

* GeniusBonus: The series contains many references to Literature/TheBible, and many characters recite scriptures (specifically from the King James Version).

** Smooth moves, priest.

** The game's [[https://www.youtube.com/watch?v=zCg2WVRESVU main theme]]. Uplifting, swelling, and a wonderful reward for getting the GoldenEnding.
** The game's 8-bit-crushed rendition of Beethoven's [[https://www.youtube.com/watch?v=rrSIw2EPpC4 Sonata No. 14 "Moonlight"]] is an iconic piece that plays throughout the game. It sets a perfect tone for the game.

** One of the bad endings of ''Chapter I'' is shooting a mysterious gray figure you can't interact with, which [[spoiler:causes Michael to [[DangerTakesABackSeat show up in the car and kill John]]]]. Who or what could this figure be? Father Garcia, who explicitly is tracking Michael after the ''Chapter II'' prologue and yet was mysteriously absent in the first chapter as an active character, and the story details in the note for getting this ending even sets up his opening. It also explains why he knows to contact John in ''Chapter III'', having seen him prove his worth as a priest and finish what Garcia had started.

* ThatOneAchievement: "Good Christian Boy" requires you to beat the game on Marathon Mode (which takes you through all 3 chapters at once instead of being accessed individually), while getting the GoldenEnding for each chapter. '''''[[NoDamageRun Without dying.]]''''' Given just [[TheManyDeathsOfYou how many traps and ways to die there are]], the fact that one Golden Ending requires you to complete an EscortMission, and how tricky and RNG-heavy some of the bosses can be, ''especially'' the TrueFinalBoss, the task is so difficult that many players who get every other achievement simply don't bother.

** The game's 8-bit-crushed rendition of Beethoven's [[https://www.youtube.com/watch?v=rrSIw2EPpC4 Sonata No. 14 "Moonlight"]] is an iconic piece that plays in Chapter 1. It sets a perfect tone for the game.

** The instant deaths most enemies and bosses give where even them spawning next to John can lead to an unexpected MORTIS. Combine this and the games having a bit of a CheckpointStarvation problem, and it can be very frustrating. Ironically, the two times this doesn't apply are the FinalBoss in Chapter 3 ([[spoiler:Gary]], which just knocks the cross out of John's hand and lets him do a last second attempt to get it back) or the TrueFinalBoss [[spoiler:against the FusionDance of Gary and Malphas, where John has a lot of extra hits he can take]].

** "Purple Girl" for Amy Martin, for [[{{ColorCodedForYourConvenience}} obvious reasons]].

** The story tries to not show its hand entirely, but the implications the latter two chapters have go a long way in implying ''far too much of the local region'' is under the thrall of the Eternal Order of the Second Death, judging by them being around every other corner or bad happening. [[ParanoiaFuel And they seem to know everything John and Garcia are doing...]]

** The true final boss of Chapter 3 is a much faster paced fight that fills the screen with different types of projectiles you have to dodge in between. The sudden escalation from slow tactical fights to full blown BulletHell action is so jarring it's more funny than scary.

** The fact you can't move while holding the cross is something that gets very annoying as the chapters goes on when you have to use it against multiple enemies or enemies that can damage sponge through it.

** The final bad ending in III can be summed up as this. [[spoiler: Initiated by John not dealing with the demonic menace in the hospital, the Profane Sabbath comes to pass and it ends the world. He tries to ask Amy why everything like this is happening to him and how he just wants the nightmares to end. Amy condemns him as "UNFORGIVABLE" and transports him to the Martin Residence, now wrecked beyond repair. He continually blames himself for what happened, wishing he never stepped into the house or that things went differently, while despairing music plays in the background. In the end, all he can do is fall to his knees while being held in place by Amy and Michael, two kids who couldn't be saved as he's finally taken by the Unspeakable.]]
** The final kicker to the above? [[spoiler: When it ends, the house is simply gone and a final game over screen appears in the same font as MORTIS: '''DAMNATIO MEMORIAE''', which is then followed by the name of the final ending, '''Ending III: The New Vessel'''. In christian terms, Damnatio Memoriae means a "condemnation of memory" akin to {{Unperson}} where a person or event is stricken from all official records. Given how much John stated that he can't handle the nightmares and wants everything to end, the Unspeakable gives it to him in a sense: ''by making it so he no longer exists to suffer as he uses him as a new vessel.'']]
* ThatOneLevel: The [[spoiler:[[VeryDefinitelyFinalDungeon home base of the Eternal Order of the Second Death]]]] in ''Chapter III'' is ''[[MarathonLevel long]]'' compared to the rest of the game, with a lot of treading back and forth figuring out what to do, and a lot of MORTIS to go around for sequences bordering on TrialAndErrorGameplay. Expect to have to redo puzzles, fights and bosses frequently as the enemies become faster, more aggressive and ratchet the game through a DifficultySpike.

* GeniusBonus: The series contains many references to Literature/TheBible, and many characters recite scriptures (specifically from the King James Version). For example, Michael's "CORRUPTION THOU ART MY FATHER" references Job 17:14, and Father Garcia's prayer at the end of ''Chapter II'' is abridged from Psalm 91.

* MemeticBadass: Father Garcia is considered this by the fandom and even Airdorf themselves, thanks to the Chapter III teaser trailer having a [[TheStinger stinger]] where he does a [[DramaticGunCock Dramatic Shotgun Pump]]. It only increased once the full game released.
** It's taken even further in [[https://www.youtube.com/watch?v=H1v0D3-TTGc this video]], which combines his badass status with a particularly [[Literature/NavySealCopypasta memorable copypasta.]]

** "{{Series/Squid Game}}" for the Cultist in Act III that forces you to play Red Light, Green Light with them.

** "THX Demon" for the [[spoiler:secret mirror boss]] in Part III, due to the loud "VRRRM" noise it makes.

* MemeticMutation: The game's use of Microsoft SAM for voiced dialogue is quite striking when mixed with its writing. Certain lines are considered quite memorable by fans.

** "RAIN OF SPIDERS!" [[labelnote:Explanation]] During the [[spoiler:first]] final battle of ''Chapter III'', the final boss has an attack where he summons a literal rain of spiders to attack John. And he ''always'' says this line whenever he uses it, and he uses it a ''lot''.[[/labelnote]]

** It's taken even further in [[https://www.youtube.com/watch?v=H1v0D3-TTGc this video]], which combines his badass status with a particularly memorable meme of its own.

** Also from ''Chapter III'', a few notes by the cult can be morbidly amusing. Like in the apartment after a rant about their doctrine, then berating members who haven't been paying their apartment rent. Better yet when you learn from another note that Gary has been [[PokeThePoodle skipping paying his rent.]]

** The story tries to not show its hand entirely, but the implications the latter two chapters have go a long way in implying ''far too much of the local region'' is under the thrall of the evil satanist cult, judging by them being around every other corner or bad happening. [[ParanoiaFuel And they seem to know everything John and Garcia are doing...]]

* {{Narm}}: The text-to-speech is intentionally supposed to be eerie and horrifying by making even the normal human characters (limited though they are) sound unnatural. Usually it achieves its effect. Sometimes it just comes off as a bit over-the-top, however, and dilutes the horror. This is especially apparent with Michael's profane rants, and one of his fleeing lines as, "I GO UNWILLINGLY," either intending to be a solemn reminder of his DemonicPossession, or a very passive-aggressive attempt at his displeasure of the cross.
