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.

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.
