Pariah (used)

Jack Mason is a burned-out doctor with no will to live, that is, until he almost dies in a transportation accident.

Now he and his infected patient are stuck deep in a dangerous prison on Earth. As a Mason, you must use your various skills, including visual and sound perception, to track and outwit your opponents. Build your own arsenal of weapons and upgrade them with weapon energy cores.

The game's vehicles and customizable weapons combine to create an intense multiplayer experience for online and offline play.
