Special Infected strategies

Kill the following special infected by using the corresponding strategies:

Boomer - Shoot it in the stomach while keeping your distance.
Charger - Get close to it to prevent it from charging, and then it will only be able to inflict one melee damage.
Hunter - When it is in its pouncing position, use a shotgun to push it back, then shoot it in the head.
Jockey - Get into a huddle with your teammates to prevent it from launching at you, and wait for it to appear. Have all teammates shoot the Jockey at the same time.
Smoker - Get close to it to prevent it from using its tongue to grab survivors from far distances.
Spitter - Shoot at the head, and dodge when it spits.
Tank - Go to higher ground, and shoot at it while dodging it. In Co-op mode, use a grenade launcher for a frontal assault while your teammates fire at its back with shotguns. Alternately, do not try to deal any damage to the Tank, but instead hide somewhere and let the survivor A.I. kill it.

Rating 3

Hunters or Jockeys strategy

Use the shove move on a Hunter while he is jumping at you to push him back, thus preventing him from landing on you. Doing this for the Jockey works as well, but does not work for a Charger who is running, a Witch, or Tank.
