Barney Calhoun

"Now... about that beer I owed ya!"

- Barney Calhoun Barney Calhoun is a former security guard at Black Mesa, until The Black Mesa Incident occurred, and he became determined to escape from the facility. With the help of Asa Kleiner-Eisen, he locates and frees Gabriel and Dr. Rosenberg, who had been captured by  HECU Troops, as well as meeting up with Dr. Isaac Kleiner. The five of them work together to recover one of Rosenberg's old teleport models, and four of the five manage to use it to escape, including him. He is described as being "out of range", as compared to Gordon Freeman, listed as "hired," and Adrian Shephard, listed as "detained".

When the Combine took over Earth, he quickly became notorious, donning an alter-ego known as "The Combine Killer", sneaking into their ranks and taking them out silently. He lived inside The Quarantine Zone for a long period of this era of his life, a place where he was unlikely to be found.

He later met back up with Dr. Kleiner and the others, and put aside his mask to join the Resistance, going undercover in Civil Protection.
