Smoking Barrels is an achievement which is earned from killing 5 enemies with explosive barrels in a single mission. This achievement is repeatable.
Tips[]
- One way to achieve this is to equip some combination of the Tesla Cannon, Prototype Rifle, and/or Freeze Grenades and use the stun effects to gather a crowd around a single barrel. In this manner you can earn this achievement on the very first barrel of the very first map.
