|Standard effects:||Explodes into a mass of disappearing flames|
|Present in:||Worms 2, W:A, WWP|
If hit by a worm's weapon, the drum explodes, scattering fire to the surrounding area, which follows the wind and extinguishes after a few seconds. If hit by a few chunks of fire, however, it doesn't necessarily explode, but instead can "heat up", which is indicated by the sprite's color. There are 3 stages of this heating, after the third one, the drum explodes.
As it can deal quite a lot of damage, players usually try to get their opponents close to it, and then attacking them, adding the drum's explosion's and the fire's effect to the weapon's. This can be done in several ways, mostly using rope and knocking the surrounding worms to the desired position, or by using the shotgun's or the longbow's first shot to hit the foes as close as possible, then the second to blow up the drum. Its fire can also be used to drown the enemy, or to knock it into a nearby mine.
When the drum is sitting on a bridge, if the worm shoots right under it with a shotgun, the drum won't explode, but it will fall down, where it can be blown up with the second shot. However, the drum can normally only move vertically downwards - despite that when landing, it bounces up a few times -, and it can't be moved by a worm, so one have to look out not to be stuck under it. Despite this, a worm can, under certain circumstances, overlap with a barrel, and two or more barrels can also overlap with each other.
Earthquake is the only thing that can move the oil drum in horizontal directions.
Depending on their positions, drums can detonate each other, resulting in a chain reaction of explosions and flames, usually killing several of the worms nearby, and greatly changing the surrounding terrain.
Although present in Worms 2, oil drums were not a scheme option. They appeared in some missions but in order to have them present for regular play, players needed to type OnDeadlyGround (case sensitive) into the landscape editor to get them to appear. In the patch, this was made a scheme option.
