Retribution is a Half-Life mod made by Chain Studios in 2002.
Tell me honestly, how many sides have you been able to play as in the Half-Life universe? Gordon Freeman (original Half-Life), Adrian Shephard (Opposing Force), Barney Calhoun (Blue Shift), and other less significant characters. In all these games, we often saw a gentleman with a briefcase, in a blue jacket and tie. Who is he, what is his goal? Not a single game gave a definitive clear answer. Now we will finally find out everything, since we play from his point of view: a man named John Bailey.
It turns out that there is a struggle at the top. There are people standing above Bailey on the career ladder, and, as usual, their plans do not include saving the world from evil aliens from the world of Xen. Black Mesa is long overdue for closure - but a certain George Weird, the head of the entire system of scientific complexes, is preventing this. So the G-Man gets a job - a revolver in his pocket and off to look for Weird!
