Bill

William "Bill" Overbeck is one of the four playable Survivors in Left 4 Dead, a Vietnam veteran who served in the US Army 1st Special Forces Group. His combat skills have helped to keep him alive, he is also the oldest of the group. In official media, he is usually seen wielding the assault rifle, probably to complement his backstory. Him andFrancis have a strenuous relationship. He is voiced by Jim French (German version: Klaus-Dieter Klebsch).

Official description
It took two eventful tours in Vietnam, a handful of medals, a knee full of shrapnel, and an honorable discharge before the unthinkable happened: Bill ran out of wars. But now an army of infected undead has declared war on humanity. After decades of aimless drifting and dead-end jobs, Bill's finally gotten back the only thing he ever wanted: an enemy to fight.

Trivia

 * Jim French, who voices Bill in Left 4 Dead, also voiced Father Grigori from Half-Life 2.
 * Bill appears to have a rivalry, a past, or just plain hatred of Francis.
 * Bill is always seen smoking his trademark cigarette. Even when he is dead it manages to stay in his mouth. However, when he dies, it is no longer lit.
 * Bill fought in the Vietnam war. If the game occurs in 2009, that would make him at least 52 years old.
 * Bill is currently the only survivor with a confirmed last name. "Overbeck" can be found on his military jacket.
