Rios and Salem are completely different dudes this time around. Instead of a third-person co-op shooter, this time you're going to be running on a through the streets of Shanghai, only having to worry about dodging bullets and killing dudes that run up to you. While, yes, you can roll and crouch, and give commands to the guy you are not playing, pretty much all you're going to be focusing on is shooting. The analog pad controls your character, and the four face buttons control the direction of your shooting. So if you want to shoot up-right, you mash triangle and circle.
