Biography
When the Combine were attacking the Underground Railroad stations, Matt manned his post to ensure that refugees coming through would get aid. Eventually, Gordon Freeman approached. Unaware of Freeman's anticitizen status, Matt made small talk that he had seen that the Citadel was on full alert, and stated that whoever they were going after (Freeman) did not stand a chance,.

Moments later, Matt recieved a report on his radio stating that the tunnels were being flooded by manhacks and he went to check outside for manhacks. Sure enough, several manhacks were there and began attacking Matt, who tried to hold them off with a lead pipe. Fortunately, Freeman decided to help him in the fight, and they soon defeated all the manhacks.

Matt thanked Freeman for his assistance, and welcomed him to the few supplies that he kept at his base. However, Matt refused to join Freeman on his journey, as he did not want to abandon any refugees that could still be coming through the Underground Railroad.

It is unknown whether Matt survived or not.

Trivia
It is possible for Matt to get killed while fighting Manhacks.
