A secret scientific research on life's final terrene days. Your consciousness serves as a vessel gathering information on a future period they dubbed Eon of the Green. Slowly but surely it takes hold of your mind and the only human factor is that colleague on the intercom.
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.
