San Francisco 49ers linebacker Patrick Willis recently got to live out every gamer's fantasy during a dream "internship" at Call of Duty: Ghosts.

Willis, a six-time Pro Bowler, got an up-close look at how the game is produced. From recording dialogue for the characters to putting on a motion-tracking suit, Willis experienced it all.

And, of course, he got a sneak peek at the highly anticipated new game, which was released this week.
