The intro scene for Left 4 Dead was a first for Valve Corporation, as they've never had an opening cutscene in their past games. As such, it went through many changes throughout production. Originally, Francis and Zoey were shown to have a sort of romantic tension between each other, and Louis would be a kind of comedic relief. However, this was deemed "distracting" by playtesters and therefore removed.

2 WEEKS AFTER FIRST INFECTION

[ ''Focuses in on deceased hand, thumb torn off, a fly buzzes around then crawls on it. The Survivors come into view. Bill puts a hand up to stop the others. '']

Bill: Hold up!

[ Bill crouches and scoops up Boomer Bile with his fingers ]

Bill (examining the bile): Ain't seen anything like this before....

Francis: Jesus. Don't let that stop you from smearin' it all over yourself.

[ Bill glares at Francis, stands up, and wipes the bile on Francis's vest. ]

Bill: They're changing.

Francis: Argh! Damn it, Bill! Awww, it stinks!

[ ''Francis wipes the goo off while Louis chuckles. Suddenly muffled crying from comes from behind a nearby door. Bill looks at the door.'' ]

Zoey: Someone's still alive!

[ Zoey and Bill, crouching, open the door to a pitch black room. ]

Bill (whispered): Over there.

[ Zoey turns the flashlight connected to one of her pistols on and, walks through the room, panning the flashlight around. The crying gradually grows louder. ]

Zoey: Hello? Hello? Hey, it's okay... We're gonna --

[ Lightning flashes; the Witch is seen crouching in a corner, and is identified as the source of the sobbing. ]

Bill: Lights off!

[ ''Outside, Louis hears unintelligible grumbling. He turns and sees a Horde approaching.'' ]

Louis: Oh, shit!

[ Francis opens fire. ]

Louis: '''Shit! Shit! Shit!'''

[ Louis runs to Zoey and Bill. ]

Louis: They're coming!

[ Louis shines his flashlight in between Zoey and Bill, inadvertently startling the Witch. ]

Louis: What the--

Zoey: Run like hell!

[ ''Zoey runs out of the room. Bill fires a few shots, grabs the door knob and slams the door shut. Louis pushes up against the door to prevent the Witch from opening it''. ''The Witch pounds on the door. On the third strike, the Witch pierces a hole through it and reaches for Louis. '']

Louis: AAAAH!

[ Louis steps back and begins shooting the Witch through the hole in the door. ]

[ One common infected reaches Francis, who shoves it away before resuming fire with Bill and Zoey. ]

Louis: How do you like that!?

[ The Witch dies. ]

Francis: Stick together!

[ ''As Louis begins to fire at the Horde, a Smoker from an above fire escape grabs Bill and hangs him in mid-air. Bill exclaims in surprise'' ]

Francis: Hang on!

[ ''Francis shoots the Smoker, killing it. Bill drops to the ground''. ]

Zoey: Guys...?

[ Francis helps Bill up and fires his shotgun at an Infected from his left and fires at another with one hand. ]

Francis: Merry Christmas.

[ Zoey unstraps a pipe bomb from her waist. ]

Zoey: Fire in the hole!

[ ''The bomb flies in slow motion through the air. It lands several yards away where it explodes, reducing the remaining Infected to a fine red mist as The Survivors huddle behind cover''. ]

[ ''A helicopter is seen flying overhead through the street, which Louis pursues. A Hunter is seen stalking him from the rooftops, and then follows him by leaping from building to building.'' ]

Louis: Hey! We're over here! We're not infected! Down here!

[ The helicopter proceeds, not seeing him. ]

Louis: Dammit!

[ ''the screen changes to the Hunter's point of view as he hangs from the edge of the roof still stalking Louis. It then leaps from the building and pins Louis to the ground''. ]

[ Zoey knocks the Hunter off Louis and opens fire with dual pistols as it staggers back; Louis delivers a final headshot with his own pistol, knocking the Hunter onto a car with a car alarm, setting off the alarm. ]

Bill: Oh, this is gonna get bad.

[ Waves of infected pour over surrounding fences and streets; a Tank is heard roaring in the distance; a car flying through the air heralds its approach. ]

Louis: Run...or shoot? ...Run or shoot?!

Bill: Both!

[ The group clamors into a nearby alley, continually shooting at the Tank and its accompanying horde. ]

[ Louis points to a ladder leading up a fire escape. ]

Louis: Get to the roof!

Francis: Go! Go! Go!

[ Francis stops at the base of the ladder, aiming his gun at the Tank. ]

Francis: Come on, come on!

[ ''Just as the Tank is about to smash Francis, Bill opens fire; the Tank retaliates by hurling its fist at him; he dodges, sending it through a brick wall. The enraged Tank grabs a slab of concrete and hurls it at Louis and Francis, who are now scrambling up the fire escape.'' ]

Louis: Heads up!

[ Bill reaches for the ladder; Zoey is seen staving off the horde from above. ]

Zoey: Go! I'll hold them off!

[ The Survivors climb the stairs to the roof of an apartment; the Tank climbs up the fire escape, but it gives way under its weight, nearly taking Zoey with it. ]

Zoey: Francis!

[ ''Francis grabs Zoey by the arm in time. Below them, the Tank falls back to the ground, the fragments of the fire escape falling onto it and crushing it. Francis and Louis pull Zoey up.'' ]

[ The exhausted Survivors take a moment to catch their breath. ]

Louis: We made it! I can't believe we made it!

Bill: Son, we just crossed the street.

[ Bill pauses to light a cigarette. ]

Bill: Let's not throw a party 'til we're outta the city.

[ Music starts to play in the background as New Orleans is shown ]

Coach: "Last time I saw my grandmotha', she asked me was I still a prayin' man. I told her: "Yes ma'am." "Well," she says; "Pray harder."

[ Three F/A-18C Hornets planes fly over the city, while the camera comes down to view a group of Common Infected. ]

Coach: "'Cause it ain't workin'."

[ Explosions start, the Infected have been alerted and start to charge toward the Survivors ]

Coach: "Heh, I ain't gonna' die wait'n on salvation. Long as we still got guns, we gonna' fight."

[ The Infected are being shot, the Charger starts to charge the Survivors and suddenly Ellis runs out of pistol ammo ]

Coach: "And if we run outta' bullets..."

[ Coach picks up a chainsaw, while Ellis holds an axe, Nick holds a frying pan, and Rochelle holds a baseball bat as a horde approaches ]

Coach: "Baby, they gonna wish we hadn't!"

[ ''The Monsters Without starts to play as the Survivors attack the horde. The new logo, game cover, release date and credits show'' ]

[ Nick walks up to an Infected on the ground and smacks it with a frying pan ]

Notes/Trivia

 * The gunfire throughout the trailer sounds like the Combat Shotgun, the P220 Pistol, the Sniper Rifle, and the Combat Rifle.
 * The Combat Rifle is only heard for a single burst before the pistol starts firing, suggesting that the Survivor ran out of ammo and switched weapons.
 * The bat sound effect is that of an aluminum bat, like that of the Scout from Valve's Team Fortress 2. In the game though, the bat is clearly wooden, but was originally aluminum in development and still appears aluminum in the game tips and the 4meleeweapons.vtf.
 * Right as the Charger charges the group, Ellis runs out of pistol ammo, even though in game the pistols never run out of ammo, though he could have simply run out of ammo in the magazine.
 * Ellis also hold his pistol with his left hand. If this is not a Developer oversight, then this means Ellis is the fourth possible ambidextrous Left 4 Dead character, the others being Louis, Francis, and Nick.
 * The entire trailer is based in 'The Parish' campaign.
 * After Coach finishes talking with "They wish they hadn't!" the Left 4 Dead theme when everyone reaches the saferoom starts.
 * The Charger seems to make unintelligent sounds and smashes other Common Infected away in an attempt to kill the Survivors. The Charger doesn't make these sounds in-game, and upon spotting the Survivors, makes a loud sound to indicate that he has seen them.
 * The song that plays when the Survivors get melee weapons is The Monsters Without from the first game.

TV Spot Trailer 2 ('Vamonos')
The second TV trailer for Left 4 Dead 2, sometimes referred to as 'Bang Bang Bang', or 'Vamonos', due to the fact it features the song 'Electric Worry' by Clutch as its theme. No dialogue features in this trailer, as it provides information through intermittent splash captions.

Zombie Survival Guide Notes

 * The scene where the CEDA agents are showcased is set in Dark Carnival; however, CEDA agents only appear in Dead Center.
 * The name for this trailer could be a reference to the Max Brook's book The Zombie Survival Guide. This is extremely ironic, as both games go against the book and its "lessons" in many ways.
 * In the video at 1:55, after Rochelle helps Nick back up from the ledge of the Coaster, there is an explosion below. The explosion does not appear in-game.
 * Ellis was the target of all the Special Infected present in the video (with the exception of Rochelle getting attacked by the Spitter along with him, and the Tank on the bridge, that attacks all four of the Survivors, but heads for Ellis).
 * At the beginning, a dog's bark can be heard, possibly meaning some domesticated animals may either be immune or haven't been infected, yet.
 * As well, at the beginning, there is a sign visible at the hotel saying, "Closed until further notice due to sickness," when in reality, it says, "Free coffee and breakfast." The sign containing the "closed until further notice" is found in-game in Left 4 Dead, on The Town in Death Toll at the convenience store across the street from the starting safe-house.
 * Small helicopter patterns are visible on the chocolate bar Coach eats, which are appropriately named "Chocolate Helicopters."
 * This explains the inspiration for Nick's sarcastic remark later on; commenting on Coach's eating habits, and his favorite brand of chocolate.
 * The song used for most of the video is also called "Chocolate Helicopter" []
 * The Smoker tongue that wrapped around Ellis mysteriously appears on the floor to his right when the camera changes view.
 * On the TV spot, the tongue and blood is completely removed from this scene.
 * The Witch is the only Special Infected not to make an appearance. The Boomer, like in the intro to Left 4 Dead, only makes a minor appearance amongst the crowd below the elevator shaft. Unlike in Left 4 Dead, the Hunter makes a minor appearance as well, only being seen when the Mud Men appear behind them on all fours.
 * At 2:40 the back of the Fallen Survivor Uncommon Infected is visible, which only appears in the DLC The Passing.
 * In the beginning, after Coach speaks, Ellis is seen carrying a Combat Shotgun in hand and a First aid kit, Grenade Launcher, and Sniper Rifle on his back. It is not possible to carry that many weapons in-game. Also, by the next scene as Ellis kicks the safe room door open, he still has his Combat Shotgun, but the other weapons on his back are gone.
 * Although the Combat Shotgun is a semi-automatic shotgun in-game, Ellis pumps it in the trailer. This is because Combat Shotgun (SPAS-12) is both pump-action and semi-automatic in real life. It might be possible that Ellis did not know of this capability yet and thus used it in pump-action mode.
 * While getting helped up by Coach in the elevator, Ellis' hand clips through Coach's for a split second.
 * Near the end of the video, Ellis loses all of his weapons while in combat, although this cannot happen in-game.
 * When Ellis throws the gas can and Coach shoots it, it engulfs the attacking Infected in flames. This is impossible to do in game. One of the Infected who attempts to get to the stage is also hit by a guitar, and Rochelle swings the guitar on the Infected like a golf stick.
 * When Ellis opens the gun cabinet there is a visible laser sight upgrade.
 * At the bridge near the end, Ellis shoots a Tank with a Grenade Launcher and it stumbles back, though in actual gameplay, a direct hit does not stumble it at all. Also, when using the Grenade Launcher in-game, an explosion should appear, however the explosion does not appear at all. It is possible that the grenade hit it but did not explode, as this is shown in other similar games such as Modern Warfare 2, as when a player is hit (not by the fragments but directly) by the grenade it does not blow up.
 * When the Survivors head toward the elevator, after Ellis shoves a Riot Infected, a Common Infected trips down, grabbing his Sniper Rifle. However, this is impossible in-game.
 * It is quite obvious where the Survivors are at some scenes. When they are walking at the beginning, it is actually the Motel from The Highway from Dark Carnival, as well as when Ellis is tackled by a Jockey. When Ellis kicks open the safe room door they are in the convenience store in The Quarter. When Rochelle and Ellis are attacked by a Spitter they are at the Milltown in Hard Rain, the Survivors are in the Gator Village when Coach says "This used the be a nice neighborhood!" Where the Mudmen were in Swamp Fever's The Swamp. When they're walking up the stairs to the roof, they are in The Hotel from Dead Center. When the military was bombing, the Survivors were at The Quarter in the Parish. When Ellis is attacked by a Charger, they are in a burning shack which is in The Shantytown in Swamp Fever. When Nick is climbing, he is climbing up The Coaster in Dark Carnival. In the scene when Nick says "I have not...", they are on the stage in The Concert in Dark Carnival. In the second scene when Nick says "Come this far...", they are holding out at The Plantation in Swamp Fever. In the third scene when Nick says "To die now...", the Survivors are at The Parish Finale. Then at the last scene when the elevator opens, they are at a lightened version of the elevator in the Atrium of Dead Center.
 * However, most events do not happen in the real gameplay; the convenience?store in The Quarter?doesn't have a barricaded stock room with weapons or a safe room door; the military bombing does not hit the Survivors when they are on the freeway in The Cemetery, or destroy the bridge in The Bridge (Left 4 Dead 2) before the Survivors crossed it; there are no large explosions during the coaster event in The Coaster; and there are very few or no zombies on the ground floor before the Survivors get to it in The Atrium.
 * In the scene with the Survivors on the rooftop of Dead Center, when Ellis says "Hey, where is everybody?" and after calling out "Hello?" and then "Anyone here?", the echo of his second "Lost Call" dialogue slightly cuts off.
 * The explosion scene after the jets bomb the bridge is the same scene from the E3 trailer, only it's slowed down a bit.
 * Ellis melees a Riot Infected before getting entangled by a Smoker at the elevator in the Mall Atrium; however, the Riot Infected is in the Parish Campaign.
 * The scene showing the Survivors fending off a horde in the Swamp Fever campaign shows the Heavy Machine Gun on the bottom porch, while in game it is on the second floor of the mansion. Notice where the Horde is coming, as they come straight for the Survivors, but when playing in-game, the HMG doesn't tend to have any targets to shoot at. Rochelle also loads the HMG before firing, although the HMG in-game doesn't need this to be done.
 * When the group is fighting the Tank on the Bridge, Nick comes to Ellis' aid using a Silenced Submachine Gun, when he fires at the Tank, it has muzzle flashes, even though in game, it doesn't actually make any muzzle flashes unless fired from a third-person perspective.
 * Also, during the battle, the Tank throws a car at the Survivors. Coach dodges the car, however this is impossible to do in-game.
 * Coach is seen wielding either a Pump Shotgun, or Chrome Shotgun through whole video.
 * There are things shown in the video that are impossible to do in game, such as Ellis' gun gets swiped out of his arms and Rochelle using the pointed side of the axe.
 * Despite having multiple floors on the Hotel, the trailer shows several stories of floors, but in-game, there's only one set of stairs leading down to the floor below them.
 * Ellis shoots the gas can instead of Rochelle, who does it in TV Spot Trailer 2.
 * Ellis can be seen carrying Tier 2 shotguns to the rooftop. Despite this, they are never seen in-game on the rooftop for balancing reasons.
 * Before the elevator opens, you can see what seem to be a reflection of Jimmy Gibbs Junior on the far left side of the elevator.
 * When Ellis shoots the first female Infected as soon as they step out of the safe-house, the gore is misdirected. While a headshot to a Common Infected from a shotgun at that range should blow the Infected's head off, the female Infected simply seems to slump down with a shower of blood, instead of limb mutilation.
 * In the beginning of the video, it shows the Survivors walking down the street by the motel near The Highway as they move on to Whispering Oaks. However, the street is blocked by a truck in the game, which forces the Survivors to navigate the motel to reach the other side.
 * At roughly 1:08 in the video, when Coach fires the Chrome Shotgun, it erroneously uses the Pump Shotgun's firing sounds.
 * At 1:44, an explosion knocks Coach back onto a police car, and Nick helps him up. In-game, the car is a red alarm car (alarm never enabled). Along with that, its almost impossible to get to the car, and in-game, when the jets bomb the freeway, players can see the car fly up and crash, but the car doesn't do that in the trailer.
 * When the Charger grabs Ellis in the trailer, it seems to let go of him. However, in-game, Chargers will always hold their victim even if they go to their maximum distance.
 * This intro is the only one that focuses on multiple locations, while the Left 4 Dead intro focuses on one location.
 * The Witch is the only Special Infected not to show up in this trailer.
 * After the smoker strangles Ellis, he is saved by Coach, but the first second shows Nick.
 * The infected that Coach punches in the face seems to attempt to escape from Coach as he is about to kill it. However, Coach kills it with the butt of his gun in a unique animation which cannot be done. Common Infected also stay on their target until they die, which is also very odd as mentioned above, the Common Infected attempts to flee from Coach.
 * At the roof scene, there is nothing found on the table near the door, while in-game you can find health, pistols, and melee weapons there.
 * The safe room door Ellis kicks open is a starting safe room door. You cannot kick safe room doors in-game.
 * At 0:16, when Nick is opening the cash register, in the background Rochelle is standing next to a red and white box of copy paper, which is identical to that in Counter Strike, another Valve game.
 * When the Ellis and Rochelle are next to each other and a Spitter comes out, Rochelle says "This is some grim shit we got ourselves into.", though this can only be heard when Rochelle is low on health, and Rochelle doesn't seem to show signs of limping.
 * When the Survivors reach the helicopter only to be left alone, Rochelle also says "This is not happening. This is not happening. This is not happening.", though this also can only be heard when Rochelle is low on health, and as above, there is no signs of her limping.
 * Before you see the scene with the Survivors reaching the hotel rooftop, when they are retreating from hordes of Infected, you can notice that Coach is holding his Shotgun as if it was a Fire Axe.
 * While Ellis is running from the Jockey, he is holding his shotgun in one hand. Jockeys are not fast enough to catch Survivors unless they keep jumping (if they miss they get to use it again and again). Notice that the Jockey is doing the same thing as the Hunter on the Left 4 Dead trailer, but jumps on Ellis soon after he touches the car.
 * Nick seems to use only the P220 Pistol in the trailer until the end of the trailer.
 * Even though Riot Infected are in Liberty Mall but only appear in the Parish, its possible that CEDA had hired them to control the riots in the mall, if any were happening.
 * When the Smoker constricts Ellis, Coach gets a Chainsaw and cuts the tongue. It is unknown where the Chainsaw came from though. When you see the tongue getting cut, it takes time in there, but in-game, the tongue is cut nearly instantly if aimed down at the tongue. Along with that, the Commons show signs of pain when being cut by the chainsaw, but in the game, they just get cut up without showing any sign of pain (likely because in-game, they get cut up very quickly).
 * At the end of the trailer, it is extremely odd how the Commons, 2 Boomers and one Smoker are waiting for them. This is very odd, as there is no noise to alert the commons, and it's very unlikely in-game, as when the players go down by elevator there is usually one or two Commons wandering around unaware of their presence. However, the lighting in the scene is very different (it seems to be dark in the trailer but light in-game), and zombies are used to being in dark areas as shown in movies.
 * In the scenes leading to the rooftop opening of Dead Center, the four survivors seem to have at least a passing familiarity with each other (most notably when Nick calls Coach by his nickname). In the level itself however, the survivors introduce themselves in the elevator, as if they had just met.
