In an interview with Machinima, Mark Rubin clarified that the fish AI in Call of Duty: Ghosts was just an effect saying, “it’s just fish, it’s an effect. It’s not a big deal. It’s not even new. I love that the internet picked up on it. I love that they picked up on Nintendo 64’s Mario, and showed that. That was awesome. That was so exactly what I wanted out of that, so thank you guys. Thank you internet.” Take a look at the video below to see how the internet took the entire Call of Duty: Ghosts reveal including the fish AI.
