"I can't say so much, but what I can say is that I am super confident and excited about where we are," Fares said. "I am so sure that this game, when it comes out next year, it's going to be something special. I'm really excited."
Fares also noted that EA has given Hazelight full creative control over their game, with very little publisher involvement. "It's 100 percent to us what we do and what goes into the game," he said. "Before I signed the contract, that was part of my thing. To be honest, working with them now is really good."
