Audio Log[]
Soldier: I don't even know what we're doing out here anymore. A few years ago I was a solider. I had a life. Sure, we did some things I wasn't proud of. But at least I had a home to go back to. Now I'm out here taking orders from psychopaths like Meilin Mao. They say she gets a kick out of feeling a heart wind down. Maybe it's time to find a new line of work.
