I need help getting the 5 day survivor achievemnet so I can get the lightsaber. I have deemed this task almost impossible though. I'm at level 50 and I've been using books to get the most out of my items. Even with that, the longest I've stayed alive is just over 1 day and 8 hours. I always run out of food and the psychopaths don't really have anything useful (besides the snipers and Adam the clown). Someone please help me. Also, does anyone out there know what the "spitfire" juice does and how you use it. Ever since I've started playing, I've never known.
