You dont collect it. You find it.
I think they wanted to add more special infected so they added a female boomer.
No, Boomer Smoker and Hunter Only I'm afraid.
The Special Infected were the Boomer, Smoker, Hunter, Tank, and the Witch. The Common Infected are everyone but the Four Survivors.
Smoker, Hunter , Boomer Witch, Horde They are feral zombie-like humans infected with a virulent strain of rabies.
Returning ones are the hunter, witch, boomer, smoker, and of course the horde. New ones are the spitter, jockey, and Charger.
He was never put into the game. They WERE actually going to put him in, but he was cut and his horde attracting scream replaced by Boomer's vomit. -horsebackrider2010

There are four playable characters: Zoey, Bill, Francis and Louis. There are also 4 playable zombies in versus mode: Boomer, Smoker, Hunter & The Tank
Yes you can be an infected in L4D. You can infected by playing the versus mode. You can be Smoker, Hunter, Boomer and randomly sometimes the Tank. It's random that what infected you are. Hope i helped = )
All you have to do is play online. Then, you just play and wait your turn. You will be a Smoker, Hunter, Boomer, or, at some points of time, you will become the tank. There is usually one Smoker, One Boomer, and two Hunters each round. Once that round is over, you will no longer be the infected and you will have to wait for the next round.
