Imagine if Eugenist has a time machine.
Only she knows the necessary password to unlock and use the machine.
She used it to send all of you back in time.
The goal of the game is to go back your own time, or any other times you like.
If you cooperate and show signs of surviving well, she will send you to any time and place you like.
If you argue, she will send you to the Apocalypse or worse.
You are sent to the garden of Eden.
