About This Game

Hi, I’m BrAId, the artificial intelligence of Mars 9.
I am here to ensure your stay is comfortable.

You have been rescued and brought to our luxurious space station orbiting Mars. As River, you will explore our leisure facilities, solve puzzles, and enjoy a life of comfort and pleasure.

Everything on Mars 9 works exactly as it should.
There is nothing to fear.

... right?

As you explore the station, you may begin to notice things that don’t quite add up. Small details. Subtle inconsistencies. Questions without clear answers.

How you act defines your experience.
Will you accept what you’re given... or begin to question everything?

  • Explore a luxurious space station orbiting Mars

  • Solve environmental puzzles

  • Interact with characters and uncover the station’s hidden secret

  • Observe, question, and interpret what you experience

  • Narrative-driven adventure with direct character control

  • A world designed to be observed… and questioned

  • Handcrafted pixel art environments full of detail

  • Multiple endings based on your final choice

Mars 9 is a place of comfort, safety, and order.
There is no reason to feel uneasy.

... is there?
