Movies aren't the only entertainment medium to have R-Rated Openings. These openings will tip parents off about the rest of the game.
- Abaddon: Princess of the Decay starts off with a Jump Scare, and then segues into a prologue of a prior expedition into the Ayakoji Mansion that the game is set in — with the professor's assistants quickly losing their minds and swearing up a storm and finding themselves surrounded by decayed corpses before they are finally attacked by a completely nude spirit. Its OVA is even worse: that begins with a dream sequence consisting of a graphic scene of Mia being violated by tentacles while a badly-bleeding Homura is Forced to Watch, followed by the tentacles crushing her with enough force to cause her head to bloodily pop off like a champagne bottle cork, rolling towards Homura as he slumps over dead.
- Arc the Lad 2 starts by showing the main character's people getting slaughtered with machine guns. The rest of the game is even worse.
- Within the first few minutes of starting up Blasphemous, the player will have most likely witnessed 1: a woman stabbing herself, 2: the Player Character waking up in a mountain of corpses and 3: that same Player Character filling his helmet with blood and putting it back on his head.
- The very first scene in the Attract Mode of BloodStorm is the Emperor's assassination, with a graphic display of his corpse cut open with his intestines spilling out and one of his eyes having been slashed out of its socket.
- Brütal Legend opens with Eddie Riggs being a roadie for a Nu Metal band. The show then goes awry when the band starts trying complicated stage stunts. Eddie then calls the lead guitarist a stupid motherfuckin' piece of shit; and a beast then decapitates the band with lots of blood. The game actually takes the opportunity to freeze and prompt the player if they would like to turn on the gore and language filters before each of these happens.
- Castlevania: Rondo of Blood begins with the Human Sacrifice of a woman, with a geyser of blood clearly visible when a sword is plunged into her body.
- The very first thing that happens upon booting up Conker's Bad Fur Day is a text that reads it's for adults only, followed by Conker killing the N64 logo with a chainsaw. The latter was removed in the Xbox versions of the game.
- Death end re;Quest, establishing the fact that it is Darker and Edgier than the average Compile Heart game, opens with the female protagonist being stabbed through the gut and having her head bitten off by an Eldritch Abomination, with the narration making it clear that her spine and organs were exposed by the former and that her head and spinal cord flew "like a nightmarish comet" from the latter, all while the male protagonist screams out in helplessness. The next scene has her waking up in a remote house no worse for wear.
- Death end re;Quest 2 starts with the new protagonist's father deciding to kill her in a fit of drunken rage while calling her a dirty whore and her sister and mother "shit". The protagonist snaps, grabs the hatchet from him, and hacks at him again and again until he's dead.
- Demonophobia: One of the very first rooms contains an instant-death trap in which you are bloodily Impaled with Extreme Prejudice through the chest by a wooden stake. It only gets worse from there.
- Deus Ex: Human Revolution does this. After a brief tutorial that involves you shooting some bad guys, you first see two enemy commanders brutally mow down any civilian that gets in their way. Then Jaron Namir shows up. By the time he's through with Adam, Adam has been thrown through a thick glass monitor and ripped to shreds, beaten to a pulp, and shot in the head with his own .357 Magnum revolver.
- The Elder Scrolls V: Skyrim starts out with your character getting sent to the execution block, watching someone getting arrowed to death for trying to run and watching someone get his head chopped off. And then the dragon attacks.
- Fear & Hunger: It is more than likely, considering the game's difficulty, for the first basic guard enemy you encounter mere minutes into a run to subject you to Prison Rape before cutting off your legs. That same guard also fights you with his "stinger" completely exposed.
- Fear & Hunger: Termina: The title screen depicts Marina, having lost one of her arms and one of her eyes, just after cutting Levi's throat. Keep in mind that in the actual game, the two are Implied Love Interests. And again, the first enemy is a janitor that fights you completely buck-naked, and if you lose, he saws off your legs.
- Final Fantasy Type-0 opens with a scene of a brutal battle between a heavily mechanized imperial invasion force and a military academy; the Empire swiftly guns down any kids they can find, and the cadets respond to this by calling down Bahamut to vaporize most of the invading army. A New Game proper begins with a wounded Izana stumbling across some other trainees, barely surviving a missile blast, getting saved by his wounded chocobo, and getting sprayed with the blood of a Militesi soldier he impales on his longsword; he then rides through and collapses on the streets of Rubrum, his chocobo gets shot, and he dies a slow, painful, terrified death. Welcome to Orience.
- Freedom Planet opens with the main villain leading an invasion into a palace, killing everyone in sight, beheading the king in front of his son (bloodlessly, but still), and then capping off the intro cutscene by proceeding to brainwash said son into his mindless slave!
- I Was a Teenage Exocolonist: The Teaser is a Flash Forward from a young adult Sol's point of view in which they are getting rescued from a burning building and the first non-human creature they run into tries to eat them and their rescuer. Just in case the mere presence of Content Warnings in the main menu and the unskippable first line of the session, which mentions mature themes, fail to convey that the game's plot is by no means a walk in the park.
- Killer7, within about five minutes of the start, has Dan Smith encounter a hooded man in a blood-splattered hotel. The man turns into a skinless monster, which he shoots in the face, followed by a muttered, "Shit." A couple minutes after that, a woman is blown up from the waist down by another of these monsters.
- The Legend of Heroes: Trails of Cold Steel starts off with a bunch of soldiers dying due to terrorists attacking the military base and lots of blood spilled.
- Lost Judgment opens with the graphic discovery of a murder victim's decaying, maggot-infested corpse. The content warning at the start isn't just for show.
- The opening of Mad Rat Dead features the protagonist getting vivisected in full view as the cheerful MAD RAT, ALIVE?
plays. - Metal Gear Rising: Revengeance opens with Jetstream Sam bloodily cutting a man in half.
- The New Order Last Days Of Europe: No one is going to believe Hearts of Iron IV is for children, much less so an alternate universe mod where the Nazis won WWII, but if you play Burgundy, the worst of the lot and the reason for a good bunch of the world's Crapsackery? You get a nice and proper Not Safe For Soul opening with one of the very first National Focuses giving you a short tale, from the perspective of a mother who never saw her baby alive, she was just told it was a boy and also euthanized before she woke up because he had "mongoloid traits". And is expected to name the dead baby for bureaucratic purposes. It serves to steel you for the rest, because it gets so much worse later that the poor kid was lucky.
- No More Heroes has Travis Touchdown decapitate a man in its intro.
- No More Heroes 2: Desperate Struggle: Travis delivers a Precision F-Strike in his very first line.
- The opening chapter of OMORI is about Omori and his friends playing hide-and-seek at a playground, followed by a boss fight with Boss. Then they go to Basil's house, where Basil finds a photo of a corpse. Omori returns to the starting room, and his only way out is to stab himself. Then the real game begins..
- The Teaser of Peret em Heru: For the Prisoners has a miner get bloodily decapitated by a hidden tripwire. Thus begins a perilous expedition in which our hapless tour group can be potentially picked off in equally bloody ways.
- Persona 5: The game wastes no time in letting players know it's Darker and Edgier, with the protagonist suffering violent Police Brutality (including being drugged) in the prologue, the Starter Villain of the game proper being a sexual predator teacher, and one of your party member's high school friends jumping off the school roof to kill herself after being raped by said teacher.
- Phantom Brave opens with Marona's parents getting killed by a creepy looking monster. After that, the opening sections of the game are comparatively lighthearted and look almost kiddy. The darkness doesn't come back into play until later on in the game. Unless you're silly enough to count little things like a mercenary first trying to murder a small child to take her work and pay out from under her, then doing so by framing her for causing the problem she was hired to solve, or virtually the entire world hating said small child because she has powers they don't approve of as dark.
- Pico's School opens with one of Cassandra shooting her teacher's head off, and one Gory Discretion Shot later, Pico starts off in his classroom — littered with the blood and bodies of his other classmates.
- After the childish-looking opening tutorial of Pound The Puss, Pound walks in on his mom having sex with a donkey, just to establish that this definitely isn't a children's game.
- Purgatory (RPG Maker) opens in the very first room, where Enri wakes up is a room with the floor and walls painted with blood and with corpses all over. This sets the tone for the Gorn that the rest of the game will be accompanied by.
- Rework the Dead: Evil: The Vanity Plate depicts the mutilated, dismembered corpse of a panda, fitting for a game involving a Beast Man bloodily slaughtering his way through a Zombie Apocalypse.
- The opening of the original Shadow Hearts has the main villain violently killing soldiers with his impish familiar. The main protagonist, Yuri, has his arm sliced off by said familiar, then cathes it and crushes its head, before reattaching his arm. He then proceeds to have a brutal fight with the Big Bad, which includes Yuri punching the villain's face in. That being said, the rest of the game is far from being this violent again.
- Shin Megami Tensei:
- Devil Survivor 2 starts with the protagonist and his friends in a train station when an earthquake occurs, a train is derailed, and, among other casualties, said protagonist suffers a very bloody Near-Death Experience.
- Not long after Shin Megami Tensei IV: Apocalypse begins, Nanashi and his childhood friend Asahi witness a high-ranking demon bloodily beat down their two mentors, followed by Nanashi himself suffering a similarly gory death at the hands of the same demon while Asahi helplessly looks on in sheer horror. Fortunately, he gets better.
- In Ultima VIII, after an expository conversation with an NPC fisherman, the first story event you get to witness is a Public Execution. That this is a Darker and Edgier M-rated game is emphasized by showing the bloody beheading without a Gory Discretion Shot.
- Previous to that, in Ultima VII, within the first 20 minutes of the game, you're asked to investigate an extremely fresh, extremely brutal murder. Again, not even a whiff of a Gory Discretion Shot.
- The Wolf Among Us starts out with a Cluster F-Bomb-spouting Mr. Toad, then minutes later gives us a violent brawl between our protagonist and a bald guy with an axe that ultimately ends up in the bald guy's skull. And he survives.
- The last few moments of Controllable Helplessness in XIII's opening (the game is a Cel Shaded comic adaptation) consist of an innocent woman in a bathing suit being graphically machinegunned to death.
