William "Bill" Overbeck is a Survivor. He is the 8th Survivor and was released in the "Left Behind" update. William "Bill" Overbeck was left for dead, an elderly man, forced to spend his days fighting hordes of undead, a much needed savior for his group, and an unrelenting wave of destruction for the flesh eaters.
Back to fight another day - It took two tours in Vietnam, a handful of medals, a knee full of shrapnel, and an honorable discharge to get William "Bill" Overbeck to stop fighting. He hated it. After decades spent drifting aimlessly through dead end jobs, Bill went in for a routine surgery and woke up to a plague turning normal people into mindless killing machines. Making his way through rural ghost towns and pitch-black forests, he found other survivors, and together they fled from the infected hordes. In the end, one of them had to sacrifice himself to ensure their safety. Bill was left for dead...and soon with a new enemy to fight.
These are perks that start off only appearing in William's Bloodweb. Starting after achieving level 30, teachable versions of these perks can be found: Left Behind at level 30, Borrowed Time at level 35, and Unbreakable at level 40. If obtained, other survivors are able to find William's perks in their Bloodwebs from that point on.
