"The sentence has been passed, now you must bring order in a world of chaos. Start with a small, low security prison and build it into a maximum-security super-max. There’s no escaping under your watchful eye because you’re in charge of every detail."
Build the walls, fences and facilities in your own prison, keep inmates from depression and violence by building gyms, libraries, hospitals and industries, arm your guards for riots, and separate the celebrity crooks, because big names are big trouble. And remember, if you don't pay your guards enough, the inmates will.
The ultimate goal is to make your small low security prison a maximum security super-max.
