If you need a walkthrough of all the steps to the objectives here it is from FrankytheMonkey, accept no substitutes:
The Basics: This is a zombie killing prison experience that will have you doing whatever it takes to get right back into prison in order to live the prison life one more time - it's just that good. Out of all the times I've been to prison this was by far the most enjoyable and that's saying something.
What We Like: You begin locked inside some prison cells but it doesn't feel overly dark, dirty or claustrophobic. It's really just an enjoyable introduction to a map that will have you spending most of your time running around an open courtyard completing objectives that are REALLY fun. Most of the objectives actually involve killing zombies as opposed to looking endlessly for painfully hidden items. The guns on this map are great, there are many perks, there is a boss that shows up in later rounds, the soul chests here actually make sense to complete and the way to Pack-a-Punch your guns is genius as well. This map just kills it in every area.
What We Didn't Like: The objectives may not be as straight forward to complete as some people might like, but its a good challenge for the serious player. Email me if you get stuck and want help.
Final Word: This map is everything that I like about custom zombie maps and once I figured out the objectives I just wanted to do them over and over again. There may not be enough room on the map to run 4 players, but solo or 2-player is perfect. This map is a must play.
