Explosive barrel

The Explosive Barrel was released within The Sacrifice DLC and has an effect that is a combination of the Gas Can and the Propane Tank. However it is almost completely stationary making it tedious to strategize with. Usually found in pairs, and when shot, one barrel will explode and spread a large radius of fire. The other barrel will be blasted a few feet away making the fire spread even further out.

Survivor Tactics

 * The barrels are a mix of a propane tank and a gas can, so you should definitely only shoot it from a good distance.
 * The barrels are great to stop hordes and are good against tanks as they damage them with the explosion and set them on fire

Infected Tactics

 * Try to incapacitate Survivors near the Barrels, as they are likely to hit them while trying to kill you and the fire and explosion will deal some good extra damage to the Survivor.
 * If one or two Survivors are incapacitated next to a Explosive Barrel, do your team a favor and stand next to it. Other Survivor players are very likely to shoot you when they see you and when they do, there is a great possibility that the barrel near you will be shot at too, making it explode and deal great damage to any Survivor nearing it. Be careful though, because if the players already know your tactic, they will likely be wise enough not to do it and kill you later. So it is likewise suggested to cover or hide the barrels if possible from their sight so that they won't be aware of your 'big surprise.' Take note though, cause this tactic can also deal massive damages to you (and your teammates) too or for worse, kill you. But if the results are very good, then it is worth doing.
