awesome article on arstechnica about the 'survivor savior'.
funny how the underground movement in this game is those that work together.
From the article:
In a world this paranoid, even a healer has his limits. “In every case if I see a[nother] survivor and they don't see me, I let them go," he says. "If they see me first, I run. If [we see each other at] the same time and we're close, I might start shooting. You’ve got to protect yourself.”
