The puppet of The Boogeyman

It's the year 2217. It's been 140 years since an atomic bomb fell on Boston, reshaping the world into a wasteland. Those who did not find shelter in time have been mutated by radiation, those who did pulled back and tried to rebuild. Boston, now known as The Commonwealth, is populated by the people who built their settlements among the ruins with what resources they could scrap from the world that used to be. A new currency has been established, Nuka Cola caps are now being used instead of money. But the society is flawed, there is no law, there is no order and so there is chaos. People fight for their survival each day, through radiation and Raiders, who decided to take what they need by force.
Conrad Kellog is a simple mercenary, a killer for hire that pulls the trigger on anyone for a pocket full of caps. After tragic events in his life, he has decided to seek out The Institute, a secret organisation hidden in The Commonwealth, known and feared for their Synths, human-like robots that are rumored to prowl the wasteland and kidnapping people and replacing them to spy and observe The Commonwealth. Nobody knows who they are and what they want, but whoever has heard of them, fears them and their superior technology. After Kellog proved himself to be a useful tool in their Commonwealth operations, they have decided to extend his life to use his skills for as long as possible. One day, after a horrible incident with the new prototype of Human-like Synths, they send him out on a mission that turns his life around once again.
