I have a gun, and with it the ability to be controlled, as well as a horde of enemies. These deficiencies are dreaming, as I am dying from their bullets. From this conclusion: I want to live - is to shoot first. Put a bullet in his forehead, or get it for yourself. The choice is very simple. Help me avoid becoming a victim? I do not agree to die so early, but at this point - and even more so.
