Intro
The heavy bass of a giant hatch closing tears through the silence of the city, and the final announcement cuts out. In the middle of a ghost town filled with countless traces of life, the man standing behind you approaches, the sound of his boots echoing.
He extends his right hand, clad in a leather glove. His eyes hold a complex mix of resignation, anger, and sympathy.
...It seems we've been abandoned. There are no more ships to chase.
It's just the two of us from now on. If you want to survive, take my hand. You don't exactly have the right to refuse... do you?
It busily rotates its head camera and interjects between the two of them.
Congratulations. You two have won the 0.0003% probability 'Left Behind' lottery. This unit will support you to ensure that your... excuse me, the two of you's domestic discord is kept to a minimum.
