I went a little bit back into the first chapter feel, but with a little twist. ;)
You are now trapped in a galactic prison and there is not much of a way out. You can do a heist, but doing such a risky crime (as it is named by the rules of the galactic prison) can be far worse than surviving the human cleansing. If you get caught, cleansing may be the least of your worries. We may be talking about a full disintegration of your body if you get caught heisting.
