Mouthwashing makes spending time with five people aboard a spaceship sound like a threat, which is exactly what it becomes. The crew of the Tulpar has survived a crash, but rescue is not coming, supplies are running out, and they are stuck with one another. Anyone curious about the game behind Karyn Kusama’s upcoming movie adaptation now has another way to find out why it has made such an impression.
Developed by Wrong Organ and published by Critical Reflex, the game asks players to piece together what happened aboard the freighter while its crew’s situation deteriorates. It is worth knowing as little as possible beyond that premise. Much of the story’s impact comes from understanding these people differently as you spend more time with them, and the discoveries are rarely comforting.
Mouthwashing joined Xbox Game Pass on October 29, arriving just ahead of Halloween. Xbox Wire’s announcement confirms availability through Game Pass Ultimate, Game Pass Premium, and PC Game Pass, with support for Xbox Series X|S, PC, cloud gaming, and handheld play. For subscribers assembling their horror plans for the weekend, it is an unsettling addition.

The Lights Just Went Out Your Nightmare Is…
Four franchises, four completely different ways of getting underneath your skin. This is the one built out of your particular fear, why it works so well on you, and what it would leave behind.
Elm Street
Your nightmare does not wait outside the door. It waits for you to close your eyes, which you are going to have to do eventually, because nobody has ever won that particular argument.
- Freddy is horror's cruellest idea: a threat that lives in the one place you cannot guard, cannot lock, and cannot avoid forever.
- You are the one who is fine during the film and wide awake at two in the morning. Your own head is where this does its damage.
- These films understood exhaustion as a horror engine. The kids on Elm Street do not lose because they are weak. They lose because they are tired.
- You can lock every door in the house. You still have to sleep.
Chucky
Your nightmare is not really the doll. It is the face of the person you tell, and the way they decide, very kindly, that you have imagined all of it.
- Chucky works precisely because he is absurd. That is the trap: the more accurately you describe him, the less anybody is going to believe you.
- You are the one shouting at the screen because the characters are not listening. You know that feeling from real life too.
- The franchise is at its best when the adults in the room are the real obstacle, and you have met those adults.
- By the time somebody finally believes you, you will have handled most of it on your own.
Scream
Your nightmare has your number, knows your name, and has almost certainly been inside your house before. The worst part is that you already know them.
- Scream is the only one of these where the killer takes the mask off and turns out to be somebody who was at the party.
- You are the person who calls the twist out loud before it lands. You watch people the same way you watch films.
- The franchise made the rules of horror part of the plot, which means the survivors are the ones paying attention. You would be paying attention.
- Everybody is a suspect, including the person who just offered to walk you home.
The Conjuring
Your nightmare is not really about you. It is about the people asleep down the hall, and the feeling that whatever is here is not interested in leaving.
- The Conjuring films are domestic horror. The house, the family, the perfectly ordinary room that quietly stops feeling ordinary.
- Your instinct is to get everybody into one room. Your fear is protective rather than personal, which is rarer than it sounds.
- This is the one franchise where belief is the weapon. The people who come through it are the ones who are not alone and refuse to be.
- Whatever is here did not come for you. It came for the household, and you are the one standing in the hallway.

‘Mouthwashing’ Is a Bleak Choice for Your Halloween Weekend
Image via Critical ReflexThe game is a first-person psychological horror experience built around exploration and storytelling. Its official description makes the crew’s predicament clear: The ship has enough power for six months, but the food will run out sooner. The setting offers the kind of isolation familiar to sci-fi horror fans, with no easy way to put distance between yourself and whatever happens next. The game’s low-poly presentation does little to soften its violence. Wrong Organ warns of extreme gore and mutilation, and its characters’ suffering gives those images weight beyond the initial shock. As Collider’s coverage of the adaptation explores, bringing this material to another medium will require a filmmaker willing to sit with some deeply unpleasant human behavior.
That film adaptation is moving forward with Kusama attached to direct and Phil Hay and Matt Manfredi writing the screenplay. The trio previously worked together on The Invitation, making them a compelling choice for a story in which sharing a room with someone can become unbearable. Scott Derrickson, C. Robert Cargill, and Vince Cheng are producing through Crooked Highway.
Per Xbox Wire, you can play Mouthwashing now through the eligible Game Pass subscriptions. If the movie announcement caught your attention, this is an opportunity to experience the original before the adaptation arrives. Just give yourself something considerably nicer to do afterward.
Release Date April 8, 2016
Runtime 100 minutes
Director Karyn Kusama
