Yay, got the Hope for the Future ending on my first run-through. I am a good android!
*SPOILERS* - happened by accident - I rapidly became disgusted with both parties and decided to rebel against both by choosing my own moral code - not to kill anyone. Because screw you guys, I'm not gonna kill for you.
And it turns out that the devs had thought of that. Really good idea, presented REALLY well - jumping controls were a bit dodgy. But everything else was excellent.
