Assassin: They are silent, come in many forms, and are giving different names like Agent, Hitmen, Mechanics, Specialist, and Professional. They all do the same thing. Taking people out with no one seeing, hearing, or every wondering till it's too late. They are the best killing machines only passed by a real killing machine. They have brotherhoods, agencies or what have you, the only thing you need to know is they will get you.

Father: I know it's not a real job, but there are two big fathers in games so far. John Marston andEthan Mars. John teaches his son how to hunt, skin, and stand for what he believes in. His son even seeks vengeance for his father. Ethan Mars is on the search for his missing son. Ethan stops at nothing to find him. He goes so far as to cut off a finger in front of a laptop camera so the killer can see it happen. Call it whatever you want, I think he just loves his son that much.

Guinea Pig: From being told "Would you kindly...." to taking down a mad computer in a science facility, there is always someone that will do or be forced to do just about anything. They may not realize what is going on right away or they know right from the beginning, whatever it be they have on tough job. They have no way of gaining knowledge of what is ahead. Why would they, their the first person to go through it. If you have to be a guinea pig try to get out of it at any cost.
