The Fire Extinguisher can only be used in Zombie File mode to extinguish fire in order to proceed to the next level. They are fed with 100 rounds of unknown ammo (Ammo HUD is missing). To use it, the player needs to aim to a fire and press the primary fire button.
- The HUD icon shows it is available in secondary slot even though it is actually in primary slot.
