In an interview with GameSpot, Battlefield Hardline senior producer Scott Probst described a player feedback program called "Game Changers". The program includes YouTubers, influential Battlefield community members, fans of competing first-person shooters such as Call of Duty, as well as general fans of first-person shooters. "At the end of the day, it's an accurate representation of our fan-base," said Probst.

Members of the Game Changers program were invited to Visceral Games' studio to participate in multiple, day-long playtesting sessions over the course of Hardline's development.

"They've been key to our success," said Probst. "They gave us very, very clear feedback on what they really like, what they really didn't like, what they'd like to see changed. And they've been working with the team even outside of their individual visits to the studio. They've gotten on email and fired away tons of thoughts."

Probst said programs like Game Changers are useful for collecting feedback on maps and game modes that aren't included in open beta versions of the game: "We've tuned a lot of specific game modes according to their feedback to make sure these things are going to serve the Battlefield community the way we want them to."

YouTubers who attended these playtest sessions were permitted to capture footage of Hardline, with resulting videos conforming to the EA Ronku sponsored video program.
