I think futuristic would be fun. I haven't done many of them, but the character that is forming in my mind would be a good fit, I think.

As for their quest, I like your idea of it being a combination. It could be that they're meant to kill someone and steal something from him without killing anyone else, no matter what happens. Your character could be trying to reason through it and come up with the best way possible while mine just charges in and plays the whole thing by ear. Something like that?
