Dark Interval is a total conversion mod, the new incarnation of the Original Storyline of Half-Life 2. You will find your way through the nightmarish world of devastated Earth. Starting from the suburbs of City 17, laying your path through the alien factories, the underwater Rebel base, war-engulfed city streets and the alien Citadel, you will feel that dark atmosphere of the Original Storyline. Development started on Apr 10, 2010.
First map after the Skyscraper. Accompanied by conscript troops, Freeman has to make his way through the Old City ruins - suburbs devastated by the 7h War — to a conscript camp located between the Old City and the New City, and then participate in the assault on the New city.
