The Charger

The Charger is a new Special Infected to appear in Left 4 Dead 2. It is described as serving to split up Survivors who are grouped up in a small place. It's not as powerful as the Tank, but it can still take a beating. It is also less maneuverable, making it easier to dodge as it charges around.

In terms of appearance, the Charger is a large Infected, roughly the size of the Tank. Unlike the Tank however, only one of its arms have been mutated while the other is small and presumably useless. It also sports blue-overalls, meaning one could assume the Charger was once a farmer, especially considering the Southern setting. Also, unlike the Tank, the Charger does not use its arms for movement, as its legs are still capable of supporting it. The Charger seems to prefer using the arm as a shield.

Like most other special Infected, the Charger has a distinctive sound. It does not shake the ground nor give off obvious music as the Tank does, but itself does seem to be loud, growling and moaning at enemies distinctively.

Not much else is known about the Charger, however, if the original Left 4 Dead campaigns are included in the sequel, it is questionable if they will be updated to include the Charger, as it seems to be created specifically for the theme of the new campaigns.
