Weapons

The main weapons in Left 4 Dead are divided into two tiers. The first is available to everyone when the scenario starts. Weapons in the second tier can be found throughout the maps and at the end of the scenario, just before the final fight. All weapons can be used to melee Infected with in close combat, pushing them back. The weapons have been said to resemble those of Counter Strike: Source, but with increased recoil.

There is no information on if there is a way to distribute ammo to other team mates. All weapons have an attached flashlight with an unlimited battery. The beam will follow the guns motion (moving up during recoil, to the sides when reloading, etc.) to let other players know where you are shooting and if you are reloading.
