Barrels are common items in all three Zombotron games. They always appear in a stage with crates. There are two different types like crates.
- Regular - Tan colored barrels. They do not have anything in them, but can save you if it is in between you and an enemy, because it will attack the barrel first, giving you time to shoot it or run away.They aren't very strong and are destroyed easily. They are like Crates ,but weaker.
- Explosive Barrels - AKA gasoline barrels. These will cause a big explosion if hit by a bullet. Enemies will also trigger them if they try to attack them. They are colored red. They can not be destroyed before exploded.
