Finale

The Finale of a campaign is something akin to a "boss fight" in other games. It is similar to a crescendo event, though on a much grander scale.

Waves
The Finale has five waves, and each wave is the same for every campaign. The Witch is the only Special Infected that is never spawned in a wave. Even though the Survivors are given a time-frame for the arrival of the rescue vehicle, it could take longer or shorter than this time depending on how long it takes the Survivors to make it through each wave.

First wave
The first wave does not begin until the Survivors have used the radio to call for help, or have started the fuel pump in the case of the Runway Finale. This wave consists of three to four groups of Horde. Smokers, Boomers, and Hunters can appear during this wave. It begins roughly ten seconds after the countdown has&#160;been initiated, and is heralded by a lound cry from the infected.

Second wave
The second wave begins once all of the Common Infected from the first wave are killed. Any Special Infected that are still alive after the first wave will continue to cause the Survivors grief. The second wave consists of an attack from a Tank. No Common Infected will appear during this wave.

Third wave
The third wave is similar to the first, but there are more groups of Horde and the size of each group is larger. Special Infected also appear more frequently during this wave.

Fourth wave
The fourth wave is another attack from a Tank. This Tank usually attacks from a different direction than the first Tank attacked from.

Fifth wave
The fifth wave begins after the second Tank has been killed. The rescue vehicle will arrive shortly and the Survivors must fight their way to it. This wave is the largest of the five and consists of several groups of Horde, several Special Infected, and up to two Tanks that all attack at the same time. Since the objective for the Survivors is to make it to the rescue vehicle, killing these Infected will only cause them to respawn to attack again.
