Acid Rain (Dead Rising 4)
DR4 Acid Rain
Type Combo Weapon
Combine Flare Gun + Chemicals
Location Kippax Cement

The Acid Rain is a combo weapon in Dead Rising 4.

To make it, combine a flare gun with any item in the "chemicals" category. It's capable of firing acid loaded rounds into groups of zombies, causing devastating acid damage.

The blueprint for this weapon is found at the Kippax Cement factory. This location is not accessible until Chapter 5, so the story must progress before being able to find this blueprint.

The Make it Rain combat trial requires 100 zombies to be killed with this weapon.


  • Press and hold Ltrigger while the Acid Rain is equipped to aim the weapon. Use Righttrigger to fire the weapon.
  • To fire without aiming, Righttrigger can be pressed to fire the weapon quickly.
