Corrosive

Example of a corrosive weapon.

Corrosive weapons are capable of splashing acid onto multiple enemies, causing them to corrode away. Corrosive damage is particularly good at eliminating Crimson Lance, Turrets and vehicles. The death animation from corrosive damage is a grisly scene where green acid splashes off the victim as they are quickly dissolved.

Corrosive acids can be formed by many objects and creatures:

• Guns are the most obvious, as corrosion can be found firing from any weapon type.
• Barrels which are green in color contain corrosive acid and explode, releasing a large splash of acid when ignited.
• Grenades can also deal corrosive damage if a "Corrosive" upgrade is on the equipped grenade mod.
• Shields can also produce an acid burst or nova when depleted. These shields can only be manufactured by S&S Munitions
• Creatures can also have the ability to generate acid. All creatures capable of creating acid are also immune to acid.
• Action Skills can be enhanced by a corrosive artifact, creating the corroding effect when used on enemies.
