Matthew Mercer is an actor who voiced MacCready, Mr. Sumner, and Z1-14 in Fallout 4.[1] He is married to fellow voice actress Marisha Ray.


Mercer began his career out of high school doing English Walla and additional characters in several Japanese anime, and has since worked with a variety of media, including video games, cartoons, and radio commercials. He has been a guest at conventions around the world, hosting at events such as Anime Expo, Anime Matsuri, Kollisioncon, and Ayacon. His work has expanded to a multitude of roles in video games, cartoon series, and radio commercials. He directed and produced the web series There Will Be Brawl, based on the Super Smash Bros. video game series, where he provided the voices for Kirby and Meta Knight and portrayed the role of Ganondorf. Mercer also produced the web series Fear News with the Last Girl, and acts as the Dungeon Master in the web series Critical Role, leading several other voice actors through a series of Dungeons & Dragons campaigns.

Participation in the Fallout series

Mercer grew up playing games in the Fallout Series. Because of the secretive nature of voice recording at the time, and that actors were not immediately told what project they were working on, he was initially unaware of what project he was performing for when he began recording on Fallout 4. However, after reading a few lines of dialogue, he realized that it was a Fallout game because of his experience with the series.[2]

    Matthew Mercer: "I had the exact same experience as Peter. Same thing, like, grew up playing 'em all... including Brotherhood of Steel, eh. Not all of 'em can be winners. But yeah, same thing, we didn't know what we were going in, as soon as you get a few lines of dialogue, and those of us who had played the previous games, it clicked and... it was just kind of, like, all of a sudden all the anxiety that built up of realizing what it was and trying not to let it affect your performance until the first break came. It was like... walking into the break room, 'Is this... is this Fallout?' They're like 'Shh...'"
