Oxygen tank

Oxygen tanks can be found throughout the game and should not be confused with the special infected tank. They can be picked up with the Use key (default: E or"X" for Xbox 360) and blow up with an explosion similar to a pipe bomb when shot. Like the gas can this weapon is usually found during mini-finales and the finale, but it can be found around some parts of the middle maps. The oxygen tank does not have as much power as a propane tank, but players should take caution, since it can be ignited while a player is holding it. When shot, it spurts flame from the hole made before exploding.
