Prison is a place that you are sent to after dying while infamous. To become infamous you must kill 4 people in 1 real life day, or 10 people within 5 days. You are only sent to prison if you are killed while infamous. Once you are sent to jail, you will be in a cell that is inside the recovery area. While in jail, you can drink beer, play heads or tails, or some other activities that don't require being outside of jail.
Prison Time Edit
Prison Time is based on how many people you killed while unfriendly. Luckily, you do not have to be online for your infamy to go down.
