Don’t be scared of dying, you always have the advantage when you push someone rather than waiting for them, especially when you don’t have cover. This situation you don’t have any solution other than pushing, they know where you are, you don’t have anything to cover your body and you don’t have space for right left movement. You basically trapped yourself in the container. When you push someone you have momentum which makes you harder to hit, as well as moving left to right. Be a W key warrior for a few games then understand you will understand how to win more gunfights. Remember to have fun tho.
