Start up Day One(multiplayer)map, make sure you have cole train. Go to the arcade, go to the Thrashball game(fooseball looking table). Keep clicking X, on the sides where you use the levers, and you should hear a faint "Woo." Cole Train, is a former professional Thrashball player for the Cougars. I did this on wingman ranked, with two cole trains, ya we were just messing around and we found this. My friend, the other cole train, was pressing X on the other side. And you can hear the "Woo" sound, but it was faint. We were also looking at the arcade screens while a guy was shooting at us, and we still killed him.
