CEDA

"Good Question. Where is C.E.D.A.? All I see are the zombies..."

- Rochelle

CEDA (Civil Emergency and Defense Agency) is a fictional governmental organization in the Left 4 Dead universe. Materials with the CEDA logo advising Survivors can be found in numerous safe rooms.

Overview
According to descriptive text on Valve's store page for the CEDA Coffee Mug, CEDA has "protected millions of Americans from the terrifying consequences of natural and man made disasters since 1988."

Involvement with containing The Infection
"Safety Checklists" with a "CEDA" logo have been spotted around the now-deserted Fairfield, instructing residents to barricade themselves in their basements and wait for help to arrive.

They also instruct citizens to seal their windows and all other openings with plastic sheeting and duct tape, implying an airborne infection. However, one sign in the safe room at the end of The Subway has been written on by another Survivor, saying "NOT AIRBORNE".

CEDA however did not want to take any chances and instructed everyone to wear face masks in case the virus was in fact airborne or it mutated to become airborne. Adults, children, as well as seniors were given a facial mask by CEDA to be worn, and if anyone required assistance they should seek a CEDA representative to help them. CEDA's idea of using the face mask was continued also by the military when they took over; as well as the TSA at Metro International Airport.



Apparently, the population is extremely dissatisfied with CEDA's safety measures and course of action, as implied by graffiti in the safe rooms of Crash Course and The Parish campaigns, which read as "CEDA BLOWS", as well as various other graffiti found all over the campaigns of Left 4 Dead 2, among the lines of "CEDA sucks".

Evacuation Centers
When the Infection first began, CEDA first tried to contain the virus by quarantining the infected individuals from the public by keeping them in isolated buildings. However, this method was unsuccessful. CEDA then had to take the next step of full town and city evacuations. CEDA then began setting up evacuation centers around major urban centers such as hospitals, arenas or malls where people were “forced” to go and await further instruction. A CEDA representative would assess the evacuation centers and provide hourly updates over all radio frequencies of the current conditions; however it is presumed that the infected individuals also made their way to those locations and quickly almost every evacuation center was overrun by the infected. With the evacuation centers being overrun, it is rumored that CEDA either became infected themselves or that they have abandoned the public completely.The Survivors usually head for the nearest evacuation center in hope for help and to be transported out of the infected area, however by the time they arrive at the evacuation center, it has either been evacuated or completely overrun by the infected.

Here is a list of some of the evacuation centers:

Left 4 Dead:
 * Fairfield Municipal Park (Unconfirmed but assumed to be overrun) This may be CEDA's first outdoor evacuation center (other than The Park ). This site was created before CEDA began the panic of thinking the virus was airborn and enforce new security measures such as face masks and have people go through decontamination trailers.


 * Hewlitt Recreation Center (Overrun) The recreation center was probably similar to a community center where CEDA set-up another evac site. This was perhaps one of the first evacuation centers to be overrun with infected. Similar to school evac sites, this was probably used as temporary shelter for citizens to take refuge.


 * Brigham Junior High School (Overrun) A junior high school located in Fairfield, this was one of possibly several schools used as an evacuation center. This site was similar in the movie:Resident Evil: Apocalypse where survivors made their way inside the junior high school.


 * Fairfield Civic Arena (Overrun) Fairfield's possible main evacuation center was the civic arena due to its large capacity capable of holding many citizens. CEDA probably focused more on this evacuation center due to the higher numbers of people and its location. However, due to its large number capability and the risk that CEDA wasn't able to screen everyone or didn't have time to screen everyone, infected people have made their way to the site and easily overran the evac site.


 * Borden High School (Overrun) A local high school in the City of Fairfield, this was possibly one of the remaining evacuation centers in the entire city (other than Mercy Hospital). With the city overrun with infected, survivors pulled out to the outer edges of the city making their way to the nearby town of Riverside possibly bring the virus with them.


 * Mercy Hospital (Overrun) Another one of the main evacuation sites in Fairfield and possibly the initial site of original infected victim. Most citizens ended up here where doctors were still trying to discover and understand the virus while screening citizens trying to separate the infected from the uninfected. CEDA possibly used the hospital and its equipment and staff to help diagnose the virus however the hospital became overcome very quickly and CEDA probably pulled out via the News Chopper.


 * Riverside First Church (Overrun) With Fairfield being overrun, the military took over the CEDA site and set up a command center in the nearby town of Riverside in hopes to keep the virus contained. Remaining evacuees headed to Riverside in hopes of rescue and were probably stuck waiting at the church until given the ok to enter the town. By then the infection had passed on from Fairfield to the outer districts and towns causing the infection to reach Riverside. The army quickly pulled out deserting any of the survivors in Riverside which soon also became infected. One of the last remaining survivors of Riverside was probably the Church Guy who finally surcame to the infection.


 * Metro International Airport (Quarantined, Bombed by the military and then overrun) Travelers from Fairfield may have gotten infected and brought the virus to the City of Newburg causing the continuous spread of the virus. CEDA tried to quarantine the airport and keep the infected away from the uninfected population of Newburg however once again they failed and the military ordered an immediate bombing of the airport. This method was very little effective because by the time they bombed the airport and the city, the entire city had already became infected.


 * Daughtery Farm (Assumed that CEDA was in control of it then taken over by the military and finally was overrun) One of the evacuation centers near Allegheny National Forest was this farm. CEDA told nearby civilians to head to the farmhouse to be rescued however, since the farm was in the middle of nowhere and the lack of CEDA and military gear and equipment, this evacuation site was easily overrun. Apparently, the City of Newburg or Metro International Airport is somewhat near this forest as a CEDA "Quarantine" poster was in the shed safe room informing people that the airport was quarantined.

Left 4 Dead 2:


 * The Vannah Hotel (Evacuated and overrun) CEDA probably screened the civilians coming into the hotel then sent them inside to be evacuated, making them wait long periods of time before they were. It can be assumed that a carrier or infected got in and infected people causing CEDA to don hazmat suits to weed out the infected. The situation quickly began to descend into chaos as people turned causing civilians and CEDA to retreat to the nearest evac station in Liberty Mall.


 * Liberty Mall (Overrun) CEDA provided shelter in the mall while they screened people and evacuated people from the area. But since malls are so big and there were so many people, infected quickly got inside and killed or infected everyone.


 * Whispering Oaks Amusement Park (Maybe Evacuated and Overrun). Park staff probably worked to shelter and entertain the civilians. CEDA either had already set up shop or quickly decided to do so in an effort to evacuate civilians (as well as the Midnight Riders). Judging by the lack of CEDA gear, tents, and trailers, it was quickly overrun from infected coming from the highway.


 * The Bus Station (CEDA once was in control of it then it was taken over by the military and was overrun) It can be assumed that the every thing was fine until the infection caught up to the evac station. With the infected at their heels, the panicked civilians rioted in an attempt to get to freedom. Knowing that it would be impossible to take everyone and make sure the virus didn't spread, the military was forced to take action and shoot all civilians outside the gate (much like the movie Doomsday).


 * The Bridge (CEDA once was in control of it then it was taken over by the military, maybe evacuated survivors and was overrun) Knowing that the situation was out of control. The military decided to save anyone they could by quarantining an area between the uninfected and the infected, only letting people through if it was confirmed they were not infected or didn't help anyone escape. But soon an infected person escaped or the number of infected grew too great and the quarantine broke. They pulled back to the bridge to hold off the infection a bit longer to let as many civilians be evacuated a possible and raised the bridge so they themselves could be evacuated, but infected were already on the bridge so many were infected before they were evacuated. (It should be noted that there is barely any CEDA equipment beyond the bus station to the bridge).

Superseded by the military
Due to failure in containing the infection and the virus becoming more of a public and national health hazard, CEDA was suspended and the US military took over all CEDA operations. Checkpoints and evacuation centers were taken over by the military who had authorization to use deadly force. Civilians were relieved when the military took over, however the military used much more "aggressive" means of containing the infection by fencing everyone up, seperating groups, and finally shooting non-infected civillians or potential carriers of the infection. Also CEDA-issued instructions on building a safe house stated that in accordance with CEDA Management Policies, no firearms or guns were permitted in safe rooms however when the military took over, they encouraged civillians to arm themselves.

Boomer Bile
"Give the infected a taste of their own medicine with this CEDA-developed gastrointestinal projectile. Any zombie you soak with this puke grenade will be swarmed by common infected."

- Left 4 Dead 2 item description

In Left 4 Dead 2 there is a new grenade item called a Bile bomb. It appears to be manufactured by CEDA (since it is dropped by the CEDA Worker Infected). When thrown the glass breaks, releasing the goo and causing common infected to swarm over whatever has been hit with the bomb. If a Survivor is hit with this they do not run the risk of being blinded nor attracting a horde of common infected to attack them.

In early development the player had the ability to throw the boomer bile at fellow survivors, but the ability was removed and replaced.
