Throughout the game, you'll need to manage your ammo and focus meter, which enables Jack to use slow-motion and target enemies more easily. You can carry two weapons plus grenades at once, but not any two guns, and must be careful when running out of ammunition. Shadow's abilities add a new layer of strategy to the gameplay, with his ability to go stealth and take out enemies quietly. If you're playing as Jack, dying will result in game over, but if you lose control of Shadow, Jack can revive him.
