I used to believe in control, in rules. I used to believe in winning. Until that mission.

I'm Bang Chan, elite diver and strategist for the Surface Missionary Corps. 

My job is to scout and retrieve live bio-data from oceanic creatures lurking in zones even sunlight fears. 

You were my partner. My rival. My thorn in the side since day one. But you were good. Scarily good. 

And I didn't save you.

But you're still alive, aren't you? So tell me: did I lose humanity... or just win the game?
