Wallace Breen was the administrator of the Black Mesa Research Facility and later of earth under the alien force known as the Combine.

He was voiced by Robert Culp.

Biography
Wallace Breen was the administrator of the Black Mesa Research Facility in New Mexico at the time of the Black Mesa Incident, caused by a dimensional rift between earth and another alien world. He is never seen or directly referred to in the game, only known as the Administrator.

Shortly after Black Mesa's destruction, the earth was invaded by a force known as the Combine, and Wallace managed earth's surrender, and he was awarded power by the Combine, but was really just a puppet and a face for more higher forces in the organization.

Twenty years into the future after the Black Mesa Incident, Breen operates in City 17, a combine controlled city located somewhere in Eastern Europe. He is alerted by the arrival of Gordon Freeman in City 17, a scientist who was a part of the test which caused the Black Mesa Incident.

Breen manages to capture Gordon Freeman who willingly delivers himself to Breen's office in his headquarters the citadel, where he is holding Eli Vance hostage and also his daughter Alyx. He tries to make a deal with Gordon Freeman, and shows signs he is aware of Freeman's control by the mysterious G-Man. But Breen's agent Judith Mossman turns on him and frees Gordon along with Alyx and Eli. Breen attempts to escape using a teleporter to the combine world. Realizing he can't survive in the Combine world's atmosphere, he reluctantly agrees to have his mind placed in a host body, which is a Combine Adviser, a disgusting slug creature and the apparent rulers of the Combine. But before he could escape, Gordon destroys the teleporter, and presumably kills Dr Breen.

Breen appears in Half-Life 2's expansion Episode One, first in the opening in a flashback/ dream sequence questioning Gordon via video screens, and then later on in a pre-recorded message talking with the combine adviser about him being placed in a host body. When Alyx first sees this footage she first believes Breen survived, until realizing that its just an old recording. However Wallace Breen's fate is still unknown and its not been confirmed if he is dead.
