What is Half-Life: Blue Shift about?

Blue Shift begins in a similar manner to Half-Life, as Barney Calhoun rides a train through the Black Mesa facility to reach his place of work. After reporting for duty, Calhoun is instructed to assist in maintenance on a malfunctioning elevator. As Calhoun finishes repairs, however, Freeman's experiment takes place and results in a "resonance cascade", causing massive damage to the facility and teleporting alien creatures into the base. The elevator is badly damaged and fails, sending Calhoun plummeting into the depths of Black Mesa. Calhoun regains consciousness at the bottom of the shaft and begins to fight his way to the surface to escape. Emerging near Black Mesa's classification yards, Calhoun learns that Dr. Rosenberg and his colleagues plan to escape the facility using teleportation technology. After freeing Rosenberg from the captivity of the US Marines detachment sent to silence the facility, Calhoun escorts him to a decommissioned prototype teleportation laboratory, where several Black Mesa employees have already gathered. Rosenberg then teleports Calhoun to the Xen border world to calibrate research equipment needed to pinpoint a teleport destination outside of Black Mesa. Upon his return, Rosenberg informs Calhoun that the teleporter's battery power has been exhausted, and contact has been lost with a team sent to acquire a new power cell. Calhoun travels to the power generators on a lower level to find a fresh power cell while firefights rage between the Marines and the forces of Xen. After returning with a new power cell, Calhoun assists Rosenberg in evacuating the few surviving personnel through the teleporter. Calhoun is the last to enter the portal and as he does so, Marines breach the laboratory and fire on him, causing the teleporter to explode. As a result of the teleporter's destruction, Calhoun enters a "harmonic reflux", causing him to be rapidly teleported to a variety of locations in Xen and Black Mesa. At one location, he witnesses Freeman's capture by Marines mid-way through Half-Life, before eventually stabilizing at the intended teleport location with Rosenberg at the outskirts of Black Mesa, where they then escape the facility in a company SUV.

Is Half-Life: Blue Shift too saturated on Twitch?

Not crowded, but not open either. Only 1 person is streaming Half-Life: Blue Shift, and that single stream holds 100% of the 1 viewers — so the room is quiet because the audience is already committed, not because it is waiting for you.
