Okay kiddo, so shoot and protect is like a game where you have to shoot bad guys and protect yourself from getting hurt.
Imagine you are a superhero, and your job is to catch bad guys who are doing bad things. But you have to be careful, because the bad guys might try to hurt you back.
So what you do is shoot them with your toy gun or your imaginary laser beams. This is the shooting part of the game. You aim carefully and shoot the bad guys so they can't do any more bad things.
But while you're shooting, you also have to protect yourself from getting hurt. The bad guys might try to shoot you or hit you with their own toys.
So you have to move around and dodge their attacks. You can hide behind things like walls or trees, or you can jump and run around so they can't hit you.
In the end, if you can shoot all the bad guys and protect yourself from getting hurt, you win the game and save the day!
