This achievement is obtained by finishing the game, watching the credits, and then waiting after they finish for a secret audio dialog to play. If you miss the achievement the first time you can redo the last level again to trigger the credits again and get a second shot. Be careful not to hit any buttons at the end of the credits before the dialog plays or it will skip it, including modifier keys like shift and alt.
