Now that is how the training of Call of Duty 4 should’ve been, while not much more than what we actually received in the game, that just seems twice as good. I loved the training zone of the game and I would’ve loved to have seen more of the area, if it had been done like this it would’ve been much better. That is what a Japanese modder named Qrysalis was able to find hidden away in the game files. Located on the blog of Robert Bowling from Infiinity Ward.
