One of the forgotten Half Life games and only a few remember it. The story of this game revolves around the forces that the scientists of the Black Mesa Laboratory called for help after the failed experiment disaster and the appearance of monsters such as Headcrap and also Vortigant who release electricity in general. The journey of Corporal Shepard begins, who aims to contain the failed laboratory experiment incident and kill the witnesses (scientists. Gordon Freeman and those in the laboratory). I remember that I played the game a very long time ago. Only old players remember this game and also Counter Strike 1.6
