Gordon Freeman, Ph.D., is the silent protagonist of the Half-Life series, and the playable character in Half-Life, and all games in the Half-Life 2 series. He is a theoretical physicist, and holds a Ph.D. from MIT in that field. At the time of Half-Life, he works at Black Mesa Research Facility, a facility in New Mexico, conducting nuclear and subatomic research.

The G-Man (voiced by Michael Shapiro) is a mysterious recurring character in the Half-Life series of first-person shooter computer games. He is known to display peculiar behavior and capabilities beyond that of a normal human and his identity and motives remain almost completely unexplained. He plays the role of an overseer and employer, both observing the player as the games progress and pulling strings to control the outcome of specific events throughout the Half-Life saga. The G-Man's constant appearances in the Half-Life games, as well as his revealing monologues with series protagonist Gordon Freeman, imply he is of great importance and somewhat anchors the endeavors of the player. His mysterious nature has made him an icon of the Half-Life series.

Barney Calhoun is the playable character in Half-Life: Blue Shift, and a major character in Half-Life 2 as well as Episode One. Michael Shapiro provided Barney's voice in the games of the Half-Life series. Scott Lynch, Valve Software's Chief Operating Officer, lent his face to the game for use in-game as Barney in Half-Life 2.
