Graffiti

Graffiti is found all over the four campaigns of Left 4 Dead, most commonly so within the safe houses. The graffiti is left by other survivors who had been through the area, generally messages, tips, and warnings for loved ones, other survivors, or simple comments, such is the case with the infamous Chicago Ted. It essentially tells the story of the game, without showing the player through things such as cutscenes. A similar approached was used in one of their earlier game series.

Graffiti has been shown to reappear in Left 4 Dead 2.

Highly Notable Instances

 * "Better safe than sorry." (Found written all over the wall in The Church.)
 * "I miss the internet." (Comment below an argument that resembles an internet forum argument in Dead Air, the Terminal Safe House.)
 * "GOD IS DEAD" (Found throughout Dead Air, referencing a famous quote by German philosopher Friedrich Nietzsche. The last time this is written, there is a dead body slumped on the wall with a pistol next to it it seems the writer committed suicide or the infected killed him)
 * "NO ZOMBIE IS SAFE FROM CHICAGO TED" (Found in No Mercy's rooftop safehouse.)

The Quarantine

 * WHERE IS CEDA?

Trivia

 * Many of the dates of death across the campaigns (mostly in The Church) used to say "-Person- May 2008". When 2009 arrived, the death dates changed from 2008 to 2009.
 * Considering the graffiti that state various dates, the earliest one refers to October 2nd, while the latest one refers to October 19th (or October 30th in The Last Stand, however, its stance as a canon campaign is ambiguous), therefore, more than two weeks span between these two dates (As opposed to the opening cutscene: "2 WEEKS AFTER FIRST INFECTION", and that is, taking October 2nd as the first day of the infection, which is unlikely), which means either the campaigns are actually connected and several days have passed between campaigns, or the developers made a mistake.
 * The verse in the Bible the "Exodus 9:15" refers to is: "For by now I could have stretched out my hand and struck you and your people with a plague that would have wiped you off the earth''.
 * The infamous "I miss the internet" graffiti can be seen here.
 * The line "John Im safe I got out and I am traveling with good people. They are immune too we are going to find a super market and fortify it. We will hide until the army comes. I love you. XOXO Sharon" may be a reference to the Stephen King book, The Mist. It also further supports the fact that there are many humans that are immune to the virus like the survivors are.
 * The mention of all the nukes may be a reference to Resident Evil 3, where the city was nuked after a t-virus infection.
 * The line "I killed 53,595" is a reference to the Dead Rising Achievement "Zombie Genocider", where the player needs to kill 53,594 zombies. A humorous reference because the survivor one upped Frank West of Dead Rising in zombie kills. Also in the game Prototype, there is an achivement to kill 53,596 infected, one more than in L4D. So the will likely be an increase in L4D2, again likely only by one.
