About this game





WARNING: The game's cutscenes potentially trigger seizures for people with photosensitive epilepsy.

After a dramatic failure of an undercover mission you become part of the top secret Klaassen Project. You are still unsettled by your past and wary about the intentions of your superiors.




Recurring transmissions take you to Earth in 1 billion years. See breathtaking things and gain the knowledge for your research. You have to find out how life deals with the deadly power of the Sun. Your task is risky though. Can you deal with its stresses and strains?


Discuss the weird future lifeforms with your assistant, Agent C. Show what you have learned during the transmissions. Along the way you carve out a unique relationship with her. You have to win her trust but keep up your autonomy at the same time. Both stats will be constantly modified by your answers and checks on them can be passed or failed. At crucial points a failed check means the end of your mission.


Agent C wants you to take a psyche test to evaluate your qualities as a researcher. Are you willing to share your true self? It might be risky to fully open up. At the same time, you might be caught lying if you don't.


Learn about Arthur Klaassen, the discoverer of Eon of the Green. Agent C will share parts of his diary with you. Haven't you heard of him before? Pay close attention to find out more about the complexities of the Klaassen Project.

  • 25k+ words of interactive fiction
