Propane tank

Information
Propane tanks can be found throughout the game. They can be picked up with the Use key (default: E or "X" for Xbox 360) and can blow up with an explosion similar to a pipe bomb when shot. Like the Oxygen tank, this weapon is used around the finales in order to set up traps. It has been speculated that this weapon does more damage at any one time than any of the other weapons. In short, it might be the most powerful weapon in the game.

Tactics

 * The explosive power of the propane tank is useful for making the tank lose its balance, and can make him stumble, giving survivors more time to escape, very useful when the tank is on fire, and you want him to succumb to the flames.


 * When shooting the propane tank, try to keep your distance because of its large explosion radius.


 * If used as a trap, try to give yourself a clear shot at it. You shouldn't have to jump out of a good cover spot to shoot it or else you may get overwhelmed by the infected and your friends might not be able to save you.


 * The Propane Tank will hurt anyone (Infected, Yourself, Teammates) once it explodes.


 * When a horde is moving around the weapon, be sure to time shooting the tank so that it is surrounded by the horde. Doing this will make the propane tank more useful for its single hit.


 * The propane tank can be carried to the next level if brought into the safe room. If found at the end of a level it can often be more useful to carry it over to the next level (Campaign and Single Player only).


 * On last two chapters of the No Mercy campaign(the ones where you can fall off the edge), the propane tank can be used to make a tank fall off the edge. Propane tanks usually spawn in the unfinished part of the hospital and sometimes the finale. When a Tank comes near an edge, the propane tank (if placed properly) can knock the Tank off an edge, instantly killing it. This tactic is useful on campaigns, especially expert, and also versus, when a Tank rushes, only to watch as he falls into nothing.
 * If a Witch is attacking a player, and someone throws a propane tank near her and shoots it, the Witch will lose a great deal of health, she will get stunned for a few seconds and be pushed back a couple feet. Additionally, the explosion hurts less than her clawing so this will spare that player a few health points and delay the Witch's attack.
