It is important to note that this game has a "Video Game
Developer" job as well as "Video Game
Designer." The achievement will only pop for the
Designer, so always double check who you're recruiting!
Otherwise, locate a Game Designer in the open world, just like HackingSpartan8, I found mine in Camden. Make them like you, pass their task, and the achievement will pop as soon as the "Press
to Swap" prompt appears. You do not need to play as the character, so feel free to shoot them to death the moment you pass their recruitment task.
