Call of Duty: Black Ops II

Call of Duty: Black Ops II Achievements

Acid Drip

In Mob of the Dead, convert a weapon using a kit.

This achievement is mostly luck based. You will need to build the Acid Gat Kit and get the Blundergat. When you get all three parts for the Acid Gat Kit you can press  to upgrade the Blundergat. Take the gun and the achievement will unlock.

  • Machine - In the Warden's Room either by the plane part or the box location.
  • Case - Around the Michigan cell blocks. It's tricky to find but if you look around every corner you'll find it. A common spot is the one to the right of the laundry room.
  • Acid Bottle - Very easy to spot. It's in the Infirmary. Either on the table or the ground in the chair room.

you can use any bench.

blundergat=stock gun

streetsweeper=blundergat pack-a-punched

acid gat=blundergat using the kit. one part in "infirmary" area, one in warden's office, and another found in the hallways general area outside spawn.

vitrolic withering=blundergat pack-a-punched & acid kit(order of pack or kit usage doesnt matter, have done it both ways)
