Imagine being chased by guys with guns and stuff. Imagine how much of an adrenaline rush that would be to know that at any point you could die. Well that's what you have with "Shooter Rumble and Fear." You are running for your life, but you have to fight back or you will die. Also, you're such a good person that you won't tolerate killing innocent civilians, and if you do, your points will dwindle to nothing. Use the mouse to aim and use the left mouse button to shoot.
