I believe he voiced the protagonist's father.

Incidentally, I have to disagree with The Milkman's opinion on that - the ending of Fallout 3 was more thematically integrated then ME3's nonsense, but it had some serious logical flaws of its own (which weren't even really fixed by Broken Steel, either).
