Barney Calhoun - "Carry my guns for me douche bag!"
Walter, commonly reffered to as douche bag by Barney, is a Black Mesa Research Facility Scientist, who is voice by Corky64 in Barney's Mind.
Walter shows almost no personality at all when first meeting with Barney after saving him from being trapped in a cargo train by HECU Grunts. However during the Barney's Mind finale, he is voiced by Corky64 and his personality, becomes that of a rival friend of Barney.
It is unclear what happens to him after he is shot unconsious by the jet during the Barney's Mind finale, though he most likey survived.
- Walter is voiced by Corky64, creator of Felix's Mind
