Otherwise, the player must wait until the next level. During "Campaign" mode, if a survivor is killed, then they will respawn in a closet or other enclosed space after a period of time (except during key points in the scenario), but must be freed by another survivor to rejoin the team. If a survivor takes enough damage while incapacitated, or is not eventually helped up by teammates, then the incapacitated character will die. If a survivor has been incapacitated and revived twice without tending to their wounds, then they will experience distorted black-and-white vision, and the next incapacitation will kill the character. If a survivor's health is depleted, then they become incapacitated and can only be revived by another survivor, at which point they continue playing with a low amount of health that decreases over time. If a survivor falls off a ledge, then they may automatically hang onto it or can only be helped up by another survivor. The game is focused on cooperation and team play colored outlines of teammates are visible through walls to help players stick together and coordinate their movement. They play through the levels fighting off the infected-living humans who have been infected with a rabies-like virus that causes psychosis, to which the survivors are immune. In campaign mode, the player takes control of one of the survivors if four human players are not available, then the remaining survivors are AI-controlled bots. In Left 4 Dead, the four survivors must fight off infected humans while trying to escape or make their way to a safe house.

Left 4 Dead will be brought to Mac OS X computers along with other Valve games in mid-2010, allowing for cross-platform support between PC and Mac versions. The popularity of the game led to the development of a sequel, Left 4 Dead 2, which was released November 17, 2009. The first of these, called the "Survival Pack", was released on April 21, 2009, with the second, in the form of a new DLC Campaign entitled "Crash Course," released for both the PC and Xbox 360 on September 29, 2009. As was done with Team Fortress 2, Valve plans on supplementing the game with free downloadable content. The game has won several publication awards, as well as distinctions from the Academy of Interactive Arts & Sciences and British Academy of Film and Television Arts. Several criticisms were aimed at limited level selection and the lack of a narrative. Left 4 Dead was well received by the industry media upon its release, with praise given for its replay value, focus on cooperative play, and movie-like experience.
In all modes, an artificial intelligence (AI), dubbed the "Director", controls level pacing and item spawns, in an attempt to create a dynamic experience and increase replay value. There are four game modes: a single-player mode in which allied characters are controlled by AI a four-player, co-op campaign mode an eight-player online versus mode and a four-player survival mode. Set during the aftermath of an apocalyptic pandemic, the game pits its four protagonists-dubbed the "Survivors"-against hordes of the infected. Development on the game was completed on Novemand was released digitally on Novemand at retail on Novemin the United States and on Novemin Europe.
