Quantum Suicide is a game of betrayal, deception and romance in the cold depths of space.
This science fiction thriller visual novel tells the tale of an intergenerational mission and its diverse crew, fighting against a deadly AI (and each other) for the chance to survive. Strategy, love interests and quantum mechanics await you. Your choices change the fate of everyone in Quantum Suicide.
You play as a researcher aboard a spaceship on an epic mission to find humanity a new home. The mission is jeopardized by a corrupted A.I system that forces you to play "The Deletion Game", a weekly game where you must battle your crew mates for survival. Prepare to make both friends and enemies of your crew members as you play through rounds of "The Deletion Game". Can you see the Everett's mission through to the end...alive?

- The romance options have their own sexual preferences - (romance and friend zone endings depending on your choices)
- Original Soundtrack
- Available in English and Japanese, with full voice acting
- Death around every corner
Can you see the Everett's mission through to the end...alive?
*Please Note: Quantum Suicide does not follow traditional dating simulator/game structure of a point or flag system - narrative branches are based on character deaths. It is also a requirement to play as both the male and female protagonist in order to achieve the true ending.
Questionable design choices, I know, but whats done is done and you have been warned :)*
Current Build Version: 29.10.211.
