You are the killer! ... But don't tell anyone. You've killed one of the faculty members and left her body in the main courtyard, heh. Your role in this game is to kill every other player while surviving yourself; therefore, it isn't a great idea to tell everyone that you're the killer. Use your wits and various tools around the school to help in this goal.Web-based multiplayer light-role-playing murder-mystery game that runs through the BYONDclient. The game is similar to standard drama fare "Knives In The Dark": one player is the Killer (hereafter referred to in male terms) and must attempt to bury the unfortunates trapped with him before dawn. Alternative game modes include Death Note mode, in which one character ('Kira') spawns with a Death Note and another has the Shinigami Eyes, forcing the two to work together in order to kill everyone else; and Nanaya Mode, an out-and-out free-for-all. The reason for it being Mitadake "High" is because the default map takes place in a high school; an external map editor allows hosts to create additional maps to play on.MH is heavily influenced by Higurashi no Naku Koro ni, Death Note, and Tsukihime, with many shout outs to other anime in the bargain. There is also an on-going webcomic (Mitadake Saga) by Frosty.After years of no real updates being made to the game, a spiritual successor in the form of Pyrce High was created, by Masterbraska, who recoded the game from scratch, adding in new modes. Suspect mode adds a new dynamic to normal mode, where a student is named by the announcement as the killer. Usually, they aren't the real killer, but to keep the players on their toes, there's a chance they could be. Zombie mode starts a player as a zombie, who can infect other players by biting them. If they can't find a cure and inject themselves with it, they'll become a zombie. Witch mode gives a player the ability to turn invisible and use various magic to kill people. They can also revive three players per round if they wish. An early version of this mode had a player spawn as Beatrice from Umineko no Naku Koro ni, instead of as a student. Bernkastel was toggleable by the host, and Ronove, Battler and Eva Beatrice could be spawned by admins. This was changed as the focus of the roleplays constantly moved away from the original intent of the game.Later on the game gained new updates with more modes. In Judgement mode, one of the students has the powers of a god and wants to use it for fun. In Doppelganger mode, the teacher was a otherworldly creature who killed a student and stole his/her body. The player who plays the doppelganger may Body Surf if he so wishes. Tsukihime mode is a revamped Tsukihime mode from mitadake high, except now instead of everyone killing eachother they created vampires and their is only one nanaya (for roleplay purposes).There also is a "Secret Mode", though this just means that the game just chooses a random mode to play.Another spiritual sequel later came out in late 2013, known as Misuterii High. It's currently still in the works, but it is playable. It added a new mode, Shiki, and changed Pyrce High's Witch and Death Note modes, Witch now called Umineko. It, unlike the Now Current Pyrce High, has no current customization, and the characters are randomized. Hey, at least you can choose the gender! Currently in the works is Madoka mode.Provides example of:
A Bloody Mess: Bottles of ketchup can be used to make puddles of fake blood.
A God Am I: Primarily occurs whenever Kira can form a cult in Death Note mode.
And Then John Was a Zombie: Happens often in Zombie Mode when a student hasn't found a cure after having a dangerous confrontation with a zombie. This happens many many times in Misuterii's Shiki Mode.
Awesome, but Impractical: Alondite. Sure, it can attack from two spaces, but it doesn't even do as much damage as an axe, burns fatigue like nobody's business, and takes up a lot of inventory room. Newbies who rely on it too much have a tendency to get batted down, robbed, and killed.
Also, there is the server setting that has each in-game hour last an actual Real Life hour. You can probably tell that it doesn't ever get used.
Axes at School: Knives can be found in students' desks, implying the more common way this trope plays out. Other weapons are found where they should be, at least on the default map - bats in the bat bin rooms, metal pipes in the basement, tasers in the teachers' desks et cetera.
Subverted when the mapmaker turns off weapons, leaving the people to wonder how the hell the teacher was murdered, and slowly go mad enough to kill themselves.
Ax-Crazy: This happens a lot with bad roleplayers, especially in the RK-rounds.
Badass: The majority of the characters.
Badass Adorable: If someone's playing an obvious Kawaiiko and using complete sentences, chances are they're both a very good roleplayer and a very good player. Attack at your own risk.
Badass Normal: Everyone, except from those with Death Notes, Shinigami Eyes or Mystic Eyes.
Some players in Pyrce High can take out large groups of players by themselves. With the knife. Given ping below a certain level of course.
BFG: The 7th Holy Scripture from Tsukihime sometimes spawns in-game. It is not technically a gun, mind you, but it's awesome nonetheless.
BFS: Alondite, a weapon that can be found, can be one of the more effective melee weapons if you fight intelligently since it can hit from two squares away — though it's weaker than the axe and drains energy insanely quickly, so if you don't kill the opponent within the first few blows, you're in a lot of trouble.
Big Damn Heroes: When you're at the mercy of the killer another student can always be your saving grace.
Body Surf: The killer has a lot of fun in Doppleganger Mode.
Break the Cutie: Find a cutie. Attempt to kill said cutie, but fail. Cutie is now broken, if they're a decent RPer.
Cast from Lifespan: In new Death Note Mode the shinigami/God Of Death can do this with Kira for the sum of kira losing half of his/her game time. For example, if the ingame time is 10 (8 hours left), you'll die when there's 4 hours left.
Catgirls: Strictly speaking, the game contains no sprites like this, but it's easy to RP as one if the server allows you to.
Chessmaster Sidekick: For Kira's side, the game is won or lost by the Shinigami Eyes. A competent Eyes can usually meet up with Kira easily, barring the usual bad luck, stupid random attacks, or a Magnificent Bastard among the other students, while an idiot will get themselves killed or keep quiet the whole game. A good Kira can win without meeting the Eyes, but it's not easy.
Cosplay: People like adding this to their character.
Couldn't Find a Pen: If you really need to write something, being covered in blood works just as well as having a Mechanical Pencil in your inventory. Bizarrely, having a weapon that is covered in blood is not sufficient if you are not bloody yourself, nor can you ever carve your message into the paper with said weapon.
Did You Just Punch Out Cthulhu?: Technically, any time Ramiel is beaten in combat. Defeating the Witch in battle will cause a similar response both from the other characters and the players.
Driven to Suicide: Serious roleplayers will do this if their character and situation requests it. Others will do it if they have to go or are bored with the game.
Dummied Out: Although Pyrce added Black Haired Girl, Pink Haired Boy is not coded to be given to anybody despite having an icon in both versions. Misuterii does have Pink Haired Boy and Black Haired Girl, though.
Easter Egg: Nanatsu Yoru and the 7th Holy Scripture from Tsukihime may randomly spawn.
Face Stealer: This is the only way the doppelganger can change its form.
Gambit Pileup: If you're playing a game with several intelligent, witty players with well-thought-out plans, expect this to happen a lot. Especially in Death Note mode. Obviously averted in Nanaya Mode.
Game-Breaking Bug: The taser bug. Tasing someone who's unconscious destroys their inventory; in the case of the holder of the Death Note, this means that there's no more Kira and the game might as well be rebooted.
Gameplay and Story Segregation: The most common argument amongst players is where the line between good player and bad roleplayer (or the opposite) should be drawn.
Genre Savvy: You need to be this for your gambit to be on top.
On the other hand, a player may have tons of evidence against someone being the killer, and decide to just outright kill them and explain when they have time. By the time you find this out, the person who found it all is already dead.
I Know You Know I Know: Experienced players tend to do this with PDA Numbers in Death Note mode: being able to instantly contact your allies is fantastic, but there's the danger that one of them is Kira and could ID you through the school's database (assuming the host hasn't disabled computers due to abuse). If you can grab a PDA off a corpse, you're all set.
Idiot Ball: A great number of games have been lost simply by Kira or the Killer getting a little too overconfident or saying the wrong thing at the wrong time, or occasionally, a paranoid idiot just getting lucky and killing the right person.
If You Kill Him, You Will Be Just Like Him: Sometimes players will try to trap the killer rather than kill him in order to avoid this. A good killer can use this to convince them to kill each other. Occasionally taken literally in Death Note mode - if someone kills Kira, the killer will (usually) pick up the Death Note and assume his role.
The Last Dance: The killer has everyone against you as well as around you, ready to kill you. What are you going to do?.....GO OUT LIKE A BADASS!
Lethal Joke Item: Wooden weapons. Even after the update that made them Breakable Weapons. (It now takes a lot more technique to use wooden weapons than it used to, but they're still wonderful for punishing heavily-armed newbies.)
I Lied: Lots of this due to the nature of the game.
Magical Eyes: One player always spawns with the Shinigami Eyes in Death Note mode, and players have a (bizarrely high) chance of spawning with them in Normal Mode, as well as a chance of spawning with the Mystic Eyes of Death Perception. Or both at once. It's happened.
Magnificent Bastard: Some Kiras take extreme joy in invoking this trope, and a good Kira or Eyes player usually either is or becomes one, especially if Kira is clearly manipulating the Eyes player to do his bidding.
Bonus points for writing your own name in the Death Note set for a time past the end of the game (say, 7:00 AM) and then giving it to your Eyes and spending the rest of the round skulking while they kill everyone, since now they can't backstab you and write your own name in.
Moral Dissonance: A good way to catch Kira is to pretend to be the Eyes, and vice-versa. This usually leads to all but you and your prey dead, followed quickly by your prey's death.
My Death Is Just the Beginning / Thanatos Gambit: This can easily occur in Death Note mode if Kira is a sadistic prick or simply cannot worm his way out of the oncoming storm. As Kira, take your Death Note, hide it somewhere the Eyes will find it, fake your own death, and hide. The Eyes will gladly kill off the other players for you, only to find that you've written their name in the back of the book for 5:00 AM. Savvy tropers will note that this is a fair recreation of the actual plot of Death Note.
Back when the game was a more cerebral experience, the announcement of certain players to play certain modes often triggered a mass exodus from the server.
Others give themselves screennames that sound menacing, such as Yandere.
When the update that allowed players to choose their own names and sprites was published, others would give their characters names that were Shout Outs to dangerous characters in other media (such as the last name Yamagi.
Never Split the Party: You go it alone, and the killer will find you. Of course, if your "teammate" is the killer, you're screwed anyway.
Ninja Looting: If you can justify it, an art form and a masterstroke RP. If not, you will be yelled at, insulted, and despised. Either way, a valid game tactic.
Particularly if, as the Eyes, you loot a KO'd Kira.
Obvious Rule Patch: People who get the role of Kira have a tendency to rush to the office, check the student records, and write every name into the note, defeating the purpose of having several dozen extra names. Now the host has the option to disable computers completely.
The security tapes seemed like a good idea when the game was starting out, but now that everyone and their mother knows how to rush the tapes in twenty seconds flat, a toggle was put in to disable them. Only after this toggle was put in did it become well-known that the tapes often lie.
One-Man Army: Most of the time, the killer must try to manipulate the other players into killing each other. But not always. There have been examples of some clever masters of the combat system defeating as many as six enemies. At the same time. In extreme cases, two of these may meet and keep on fighting for the whole round.
Something Completely Different: Nanaya Mode. No RPing this round, just Kill 'em All, unless the host defies the trope by managing to get everyone under control before the round starts. When this happens, you often get a well roleplayed and interesting game. (Of course, it's still something completely different.)
Spanner in the Works: Almost everyone who has been Kira or the Killer has constructed a brilliant plan only to have one person completely ruin it, often without realization.
There Can Be Only One: " Nanaya test sequences about to begin. Any staff still present in the building should vacate immediately. For test subjects in the building, your purpose is simple; if you wish to become the new 'Nanaya', or simply wish to live, kill everyone but yourself. That is all.''"
Unwitting Pawn: You have no idea. Especially likely to happen when there's a personal relationship between the two players.
Video Game Caring Potential: The killer has a tendency to choose one student (of their preferred gender) and spare them. This doesn't always happen, mind you, but more often than you'd think.
