Bill

"...Portraying Bill as a once heroic army veteran, who though older and wiser, can still excel at physical combat."

- Ariel Diaz, Valve

"Bein' brave doesn't mean you're not scared. It means you're scared as hell, and then you pick up the shotgun anyway."

- Motivating an incapacitated Survivor he is reviving William "Bill" Overbeck is one of the four playable Survivors in Left 4 Dead.

He is a Vietnam veteran who served in the U.S. Army 1st Special Forces Group, and is the oldest of the group. He is usually seen wielding the Assault Rifle (which appears as the M16A2, a real-life assault rifle used by the U.S. Military after the Vietnam War). He often has a lit cigarette in his mouth that only extinguishes when he dies.

Bill is killed prior to the events of Left 4 Dead 2's "The Passing" during the (canonical) events of "The Sacrifice". According to The Sacrifice comic, Bill was attacked by multiple Tanks after he went down to reactivate the stopped lift bridge generator to save his team from the oncoming Horde.

Bill's facial features are based on Bernard Fouquet and he was voiced by the late Jim French.

Background
Bill served 2 duties during the Vietnam war, during which he suffered a knee injury as a result of shrapnel boring into his knee, causing permanent damage. Two days after the first Infection, Bill was at a veterans hospital waiting for an operation, possibly relating to his knee injury. When a resident staff attempts to make small talk in regards to Bill's missing family along with his smoking habits, Bill tells him to go practice somewhere else.

As he undergoes anesthesia and slowly blacks out for the surgery, one of the nurses becomes an Infected and kills the operation room staff. Bill somehow staves off his oncoming unconsciousness through sheer force of will as he simultaneously fights off the Infected nurse, disabling her momentarily. Finding a bone saw and a knife to defend himself with, Bill fights the sudden rise of Infected outside the hospital to make it back home, where he equips his old military clothing which had been put away for safekeeping.

Relationships with other Survivors
Out of the other three Survivors, Bill stands out most prominently as the leader of the group.


 * Francis
 * Bill appears to have some sort of rivalry with Francis, though the precise reason for this is unknown. It is possible that Bill and Francis knew each other prior to the outbreak, and Francis's in-comic comment about knowing Bill the past few weeks suggests this too. Another cause could be Francis's supposed hatred of the military (since Bill was once a soldier), instinctive alpha-male rivalry, or simply Francis's gruff personality rubs Bill the wrong way. Alternatively, what is said could simply be friendly teasing between the two. Even when Francis is dead, Bill can be heard mourning about his death, showing at least a little respect for the latter as he will sometimes say if he sacrifices himself, "Christ, I'm gonna miss that son of a bitch."
 * In The Sacrifice comic, while Bill still doesn't particularly get along with Francis, he considers Francis as 'his own', and will desert any newcomer if they have a chance of endangering his group. Francis, despite all his insults, knows Bill well enough to know even when Bill doesn't do the right thing, he does it for the right reasons. When Bill leaves the group to sacrifice himself and does not return, Francis is the first to attempt to go down to bring him back, but is stopped by Zoey as the reality of the situation sinks in, and they mourn for his death.
 * In "The Passing", Francis is sometimes not happy that they have to lower the bridge, since it was due to Bill's efforts that it was raised in the first place. Also, Francis may be heard saying that they lost a good man getting the bridge up, showing he may secretly respect Bill.


 * Louis
 * As far as the Survivors' relationships go, Louis and Bill do not have much evidence hinting towards each other's dispositions. Bill will, however, seem genuinely upset to see Louis die. Oddly enough, this is in contrast to how unsympathetic Bill can be when Louis is incapacitated outside of the safe room. However, he'll usually follow this by saying he was joking.
 * In The Sacrifice comic, Bill is able to see when Louis is planning something (such as ramming a jeep leaking gasoline into a Tank) and react accordingly, and shows surprise at his intuitive thinking. Similar to how he treats Francis, Bill prioritizes the safety of Louis as one of his group above others, even if it means their deaths. Bill also told Louis once they make it to the Keys he'll make him a fishing pro. Louis also bonded with Bill after showing the older man how to make Pipe bombs, although it is not shown, having been a remark by Francis to Zoey.
 * In "The Passing", Louis is sad that Bill is gone, but is resolved more than ever to stay with Francis and Zoey. When killing a Tank, Louis may proclaim the kill in Bill's name for revenge.


 * Zoey
 * The relationship between Bill and Zoey is fairly strong. Bill is openly sorrowful when Zoey is killed. When Zoey is incapacitated on the other side of the safe room, Bill verbally refuses to leave her behind. Bill seems to view her as a daughter or granddaughter figure. This is strengthened in Part One of The Sacrifice comic as Zoey is seen resting closest to Bill on the evacuation vehicle, and in that he mentions her name first when he's reflecting on sacrificing himself to save the others. To further illustrate this, he attacks a soldier who hits Zoey with his gun when demanding she show the doctor her wound, and when she reflects on how her parents died, she hugs Bill, finding comfort in his arms.
 * Their relationship is strained deeply in The Sacrifice comic when he refuses to stop the train to allow the other newer Survivors on board due to his need to protect his group, of which Zoey is a part of. Later on, Bill sacrifices himself to save the other Survivors, leaving Zoey with sadness, as they never really made up prior to their separation. She takes up Bill's conviction to "look after their own" in his place. During his initial jump down the bridge, Bill mentally vents his anger at the Infected, thinking how every time he thinks "she's" safe and he can rest, they're there again like a bad nightmare. "She" in this case most likely refers to Zoey.
 * In "The Passing", if Louis and Francis joke about Bill, Zoey may look away or appear very sad, hinting that she is the one who misses him the most.

The Survivors of Left 4 Dead 2 did not meet Bill before his death. However, Francis and Louis joke that Bill would probably have shot Nick quickly due to the latter's disagreeable personality. Rochelle shows understanding and sympathy to Bill's death in certain lines to the original Survivors. Both Coach and Nick have multiple lines regarding the loss of Bill if his death is mentioned.

Behind the Scenes
Bill's original beta design was relatively similar to his current appearance. The main differences are in his clothing: a dark olive jacket with a hood and the POW flag on the right shoulder, beret with the 5th SFG insignia, a black military assault vest with the U.S. flag, dark gloves, and dog tags on the neck.
