Chainsaw

The Chainsaw is a new Close Combat weapon intruducted in Left 4 Dead 2. It is assumed to be found in one of the swampy campaigns in Left 4 Dead 2 as it was not seen in the beta footage yet.

It has unlimited uses, meaning that it can be very useful when the Survivors run out of ammo in a middle of a combat and in too much danger to use the Pistols in critical such as Hordes with an Hunter inside of the horde and so. Like the other Close Combat weapons it can kill every common Infected in one hit, but it has it's disadvantages as the Survivor cannot use any other weapons while carrying the Close Combat Weapon, making it extremely dangerous when facing Special Infected, as it will take couple of seconds to throw it and run to help the helpless Survivor.

The Chainsaw is not meant to be used against Special Infected, using it on a Boomer will spread the slime over the Survivor/s, against a Charger, Hunter and Smoker will take time for the Survivor to reach it, making it a dangerous situation, and against a Witch or a Tank will do little to no damage at all, so the Chainsaw should only be used against Common Infected and hordes of them.
