Frequently asked questions
- How hard is this Signalis quiz?
- The opening questions cover things you learn in the first hour. It gets harder towards the end, with questions that lean on notes, diaries and letters found around Sierpinski and Rotfront.
- Where do the answers come from?
- Every answer is taken from the game itself, as covered on our cited explainer pages. Nothing comes from fan theory.
- Does the quiz ask about what Signalis really means?
- No. Questions like whether Ariane is the dreamer are readings, not facts the game states, so the quiz leaves them out and sticks to what is on the record.

Followed from this entry
Adler: the Administrator Who Remembers the Loop
Adler is the ADLR administrator of S-23 Sierpinski, the Replika who throws Elster down a lift shaft and later blocks her at the red gate. His diaries show a bored bureaucrat slowly realising that the same days keep repeating, and that Elster has been here before.
Ariane Yeong: the Pilot at the Heart of Signalis
Ariane Yeong is the human pilot of the Penrose-512 and the person Elster has been searching for all along. Her notes, her school records and her room in Rotfront tell the story of a lonely art-loving girl who ran away to space and fell in love with her Replika.

Elster: the Replika Who Crossed Leng to Keep a Promise
Elster, unit LSTR-512, is the Replika you play in Signalis. She wakes on a crashed ship, searches a dying labour facility for someone she can't quite remember, and slowly works out that the person she lost is Ariane Yeong, the pilot she served with on the Penrose-512.
Falke: the Commander Who Looked Beyond the Red Gate
Falke is the FKLR unit who commanded the Protektors of S-23 Sierpinski and the final boss of Signalis. She crossed the red gate in the mines, came back sick, and was slowly overwritten by Elster's memories until she could no longer tell the two of them apart.
Isa Itou: the Girl Searching for Her Sister in Signalis
Isa Itou is the Gestalt Elster keeps running into at S-23 Sierpinski, a girl from Rotfront looking for her lost twin, Erika. She was Ariane's school friend, and her story ends in her family's bookshop.
The Penrose Program: One Pilot, One Replika and No Way Home
The Penrose Program was the Eusan Nation's deep-space scouting mission, sending one human pilot and one Replika per ship past the edge of the solar system. Its briefings, found aboard the Penrose-512, show a mission that expected its crews to die.
