Shoot your enemies. They are all over the place. You have to quick and you must kill them before they can shoot your head. Don't worry. You can hide behind your car.

Run, roll and hide behind anything that you can use as a shield. Locate your targets and kill them using your gun. Beware. Some of them could attack you from your back.

Hide behind a solid object and use your keen eyes to track your target. Kill them without showing any mercy. No matter what, do not allow yourself to be caught empty handed.
