Upon escaping the prison you are supposed to go to the criminal base, get yourself some weaponry, and go out robbing stuff here and there.
The bank and the jewelry store are just blatant copies of the bank and the jewelry store in Jailbreak, while the casino and the night club are actually something that I did not see in other prison games. And, for some reason, there is a pyramid thing… There is also the cargo ship which sometimes arrives at the port for a couple minutes, allowing you to get there and rob it. Oh, by the way, trying to skydive onto the cargo ship will just end up with you casually sliding off into the ocean.
