The Charger is a Special Infected introduced in Left 4 Dead 2. His main purpose is to separate a group of Survivors who are close together by grabbing one and carrying them away while crashing into the rest of the group, sending them flying through the air. While he matches the Survivors' pace, he speeds up considerably when charging. However, the Charger cannot stop or turn during the charge until he hits a wall or travels a certain distance.
Appearance[]
The Charger is a large Infected, close to the Tank in height, and about half as wide. Unlike the Tank, the Charger's legs are capable of supporting all of his weight, and thus stand mostly upright. His hairless skin is a deep greenish-gray in color, and he wears bloodstained denim overalls with one broken strap and a green sneaker on his right foot.
Extent of Mutations []
The Charger's mutations appear similar to the Tank's mutations in terms of increased muscle mass, though noticeably asymmetrical. Most notably, the Charger's right arm and shoulder have grown significantly and have increased in thickness, resulting in his right hand becoming a swollen lump with stubby fingers. This causes him to lean to the right while moving. His left arm, inversely, has atrophied to the point of being useless (possibly from his body breaking it down to add bulk to his right arm), hanging limply to the Charger's side and flapping around with every movement.
His legs are less visibly affected by the mutation, with only his left leg gaining any sort of extra bulk (to the point of ripping his overalls) while the right leg's proportions remain normal. The leg mutations are possibly to balance the Charger, equalizing the weight distribution throughout the body and enabling him to move quite fast.
Due to the Charger's preferred method of attack, he has sustained multiple injuries, especially on his right arm―prolonged times of bashing and slamming into walls has made the flesh of the Charger's right arm thick with calluses, scabs, and scars. Most likely a result of his constant charging, right half of the Charger's face is visibly damaged. His cranium has a large dent, he lacks teeth, and his nose is completely removed, with blood running from it.
Like other Special Infected, the Charger has a distinctive sound. He is loud, making noises vaguely similar to human speech and barking at enemies in a high-pitched tone. He will also screech upon spotting Survivors and release a loud yell when charging.
Abilities[]
While charging, the Charger will run quickly forward with his right arm raised in front of him, using it to grab a Survivor. He will run faster than a healthy Survivor while charging.
If he fails to grab a Survivor, he will automatically stop upon running 80-90 feet if no obstacles are in his way. If he does crash into an obstacle, then he stumbles and takes 2 damage from his crash. Should he grab a Survivor, then they take 15 damage regardless if they crash into an obstacle or not. Once he grabs a Survivor and stops, he will begin smashing them against the ground, ceiling, or wall repeatedly until they die. Nearby Survivors can be sent flying into the air if they are near the grabbed Survivor, dealing the same amount of damage to them, along with any potential indirect damage.
