Try yourself in passing various locations with their own features and difficulties. Each location has its own enemies who have their own abilities or they are just stupid NPCs who just run in different directions. Use improvised items in order to go further and not die. Also, don't forget to light a cigarette and drink some cheap elite beer if your health is at rock bottom!
