## Description
The year is now 2117. You are a second generation ship-born researcher studying inter-dimensional travel. Your choices change the fortunes of all aboard the Everett. Friendship and love lay waiting at your feet, but you should be wary. The road to the stars is full of hardship. 

A malprogrammed A.I. dedicated to preserving resources pulls you into a twisted, murderous game. When tensions are high, who knows what even the kindest crew member will do? How will you protect those you love? Will you betray friends to save yourself? Will you be slaughtered in cold, empty space? Will you slaughter?

It's time to ask yourself: what would you do to survive?
