Left 4 Dead 2 is a first-person shooter with a heavy emphasis on cooperative gameplay. The game presents five new campaigns, each composed of three to five smaller maps. In the first two to four maps of any campaign, the survivors attempt to reach a safehouse, while the final stage requires the survivors to call for rescue and either survive a prolonged onslaught until rescue arrives, pass through an especially challenging gauntlet of infected to reach a rescue vehicle, or (in Dead Center) collect and deploy fuel cans to facilitate an escape.
Each survivor can carry one main weapon, and either a melee weapon or pistols as a secondary weapon. Though melee weapons cause extra damage to the infected when struck, the survivors can use any other weapon or item for weaker melee attacks and to temporarily push the infected back. Players also carry a flashlight which has infinite battery and makes it possible to see in the dark, but also causes infected to notice the survivors much faster. They may also carry a single first aid kit, special ammo pack, or a defibrillator; in addition to either pain pills or adrenaline shot. They may also carry a single throwable weapon—Molotov cocktails to set an area on fire, pipe bombs to attract any nearby infected to the flashing light and sound it makes until it explodes, and Boomer bile, which can be thrown at infected to cause them to turn on each other.
Because many of the special infected can quickly finish off a survivor if they are not rescued, the game encourages players to stay and work together to traverse the level safely. To enable situational awareness of other players, players are shown the health and status of their fellow survivors. If a player does not have direct sight of another survivor, they will be shown the survivor's highlighted silhouette. As they take more damage from the infected, players move slower. If a survivor's health drops to zero, they become incapacitated and can only fight off the infected using pistols—even if they are carrying a melee weapon—until rescued by another survivor. If a character dies, they remain dead until the next level, unless revived by a defibrillator, or, in Campaign or Single-player mode, reappear in a "rescue closet" to be freed by the other survivors. Should all the survivors be killed or incapacitated, or if all the human-controlled survivors die, the game is over, and players must restart that chapter.
