Half Life 2

A first-person view shows a player holding a rifle, approaching a wall-mounted first aid station with a red cross and a digital display, then turning to face a wooden H.E.V. (Hazmat Environmental Vest) charging station with a green light and a coiled cable. The player moves from the first aid station to the H.E.V. station, which is mounted on a plain gray wall in what appears to be a sterile indoor environment.
