Half-Life: Blue Shift - Chapter 5: Focal Point

Barney Calhoun and Rosenberg reach an older part of the Black Mesa Research Facility where a disused teleporter system is being reassembled by scientists. To make the teleporter completely operational, Calhoun is forced to travel to Xen and activate a device to allow teleportation to happen. Notable in the older part of the facility are older-looking models of health and HEV chargers and the use of hand scanners instead of retina scanners for identification.
The remainder of the game takes place in an abandoned, walled-up sector of the base originally built for research of the first teleporter device. Calhoun, Rosenberg, and two other scientists (Walter Bennet and Simmons) try to restart the prototype teleporter. Calhoun is briefly teleported to a ruined human research camp on Xen to operate a triangulation device.
Trivia
The name of this chapter comes from physical term focal point. In optics a focal point is the point at which initially collimated rays of light meet after passing through a convex lens, or reflecting from a concave mirror.
This chapter takes place at the same time as the Half-Life: Decay chapter Rift and the Half-Life chapter Blast Pit.

9:11 I do like that part where Rosenberg is pleading for Calhoun to hurry up, somehow being heard through the portal.
Listen closely, you’ll hear it.
