\n主要的玩法循环是推进一系列独特的战役。每个战役都由多个紧张的关卡构成,中间穿插着被称为“安全屋”的检查点。这些安全屋提供暂时的喘息之机,但在幸存者们必须再次出发面对下一波猛攻之前,他们需要补充资源。在每个战役的终点,目标都是成功撤离,这要求团队成员进行协调一致的努力和资源管理,以度过最终的对抗。
\n\n在机制上,游戏极度依赖合作生存。玩家必须共同管理弹药、生命值以及在数量上占绝对优势的感染者面前的站位。环境本身也经常发挥作用,提供可能帮助或阻碍团队前进的动态元素。

The survivors have noclipped out of reality and are now trapped in the Backrooms. Now all you have to do is survive because you are not alone...

"The Last Stand" is a two-map campaign remake of the Left 4 Dead survival mission of the same name, made by the Left 4 Dead 2 community. It was released as part of The Last Stand Update—the fourth DLC for Left 4 Dead 2—on September 24, 2020.

5 awful maps for awful people. Me and my buds love playing stupid left 4 dead campaigns, so I decided to make my own.

Left 4 Dead: Survivors is an Japan exclusive arcade game released on April 30, 2014.

A 5-map campaign, a sequel to 'Questionable Ethics'.

This DLC is a custom campaign developed by Matthew Lourdelet, the developer of 2 Evil Eyes and eventually made official by Valve. This DLC features the rest of the original campaigns from Left 4 Dead, Death Toll, Dead Air, Blood Harvest, as well as the later addition of Crash Course. They were ported over to Left 4 Dead 2 in a similar fashion with No Mercy when The Sacrifice was released, featuring the Left 4 Dead Survivors.

A custom campaign for Left 4 Dead 2 based on the video game Alien Trilogy.

Survivors got stuck in a mysterious research facility. This campaign is about randomness and some traps.

This DLC is a port from Left 4 Dead, adding the campaigns The Sacrifice and No Mercy. Initially, it was to be released for the first game alone, but since players would have to own Left 4 Dead to experience the events that explain The Passing, the developers opted to release it for both games. No Mercy was brought over as well because it was the most popular campaign. Both campaigns are available in every game mode. Players will still control the original Survivors, but will find items and Special Infected from Left 4 Dead 2. Five achievements were added, as in Left 4 Dead.

The first DLC for Left 4 Dead 2. Entitled "The Passing," players will control the new Survivors as they meet up with three of the original Survivors from Left 4 Dead in a campaign that takes place between Dead Center and Dark Carnival. A new firearm, the M60, and a new melee weapon, the Golf Club, appeared, along with a new "Uncommon Infected," the Fallen Survivor. New Survival, Versus, and Scavenge maps were made available. It was released April 22, 2010.
