From Horror MUX
Horror MUX is a game of mortal horror set in a variety of rotating settings and themes, using different versions of the same characters, and with an underlying connection running throughout.
This is not your normal MU*. You don't write a background and 'make' a character. Players choose an Archetype for their character to embody, and that Archetype takes on a new character/role in each story, given to them by The Director. You decide their gender, name, age, ethnicity and appearance, as well as their personality (informed by the chosen Archetype), but the role they play in each story is assigned by The Director (again, informed by the chosen Archetype), along with hooks for the current story and often some supporting characters you can emit. This way, you get to play who you want to play, but you also play what the story needs played. Stories run as long as they take - each has a specific 'ending', often involving escaping an area, surviving until a certain time, or in rare cases defeating the danger(s). Fighting or killing the danger is rarely a good idea and simply surviving is usually the best strategy. It will usually - but not always! - be clear what the goal is. Examples include getting off a xenomorph-infested space station, surviving on an island until rescue comes, escaping a haunted house that's trapped its inhabitants, and so on. A story can also end with the deaths of all active Archetypes. In this game, there CAN be unhappy endings.
In between stories (or upon death in a story), Archetypes find themselves trapped in an isolated place known only as The Facility, with no memory of who they are - or if they're real people at all! - but full memory of each story they've experienced and the role they played. There are no other people in the facility outside of the Archetypes, no cameras seem to watch them, food is provided by dispensers, and there is no exit or any windows. Each Archetype has a personal quarters consisting of a bedroom and bathroom, and clean clothes befitting the Archetype are provided. All of their needs are taken care of by unseen benefactors - or jailers, depending on point of view. This existence goes on without any clue as to day or night, season, or year. They can do as they please while in the facility - eating, sleeping, recreation - whenever they please. Sometimes new Archetypes show up, and sometimes old ones just disappear.
Without warning, all current Archetypes will eventually become sleepy at the same time, and once asleep, find themselves in a new story. Once inside, they remember nothing of the facility or past stories, and simply become the role they are assigned. The only ways to leave the story are to die in it or to finish it. Upon death or completion of the story, they wake up back in the facility. The rest of the Archetypes are nowhere to be found until they, too, die or finish the story.
To allow players a way to continue within the story in the event their Archetype dies, they may continue to play any surviving Supporting Roles they have. Their Archetype, now back in the facility, has no knowledge or memory of those events, however. Archetypes may also resume facility RP with any other Archetypes that have died if they wish. A player whose Archetype has died in the story, has no remaining Supporting Roles, and no fellow dead Archetypes with them in the facility may be given a Central Casting character to play. This way there should always be something to do.
Over time, your Archetype will begin to evolve and flesh out, becoming more of a person as the stories and experiences shape them. Facility RP will become more interesting as the Archetypes turn to each other to try and make sense of it all and figure out what's really going on. There IS a deeper meta-story, and things WILL slowly unravel over time.
