"Stops the virus' growth for a short time."
Dr. George Hamilton can create Anti Viruses with his medical kit. Two Green Herbs are needed to create one Anti Virus. In File #2 he can create two Anti Viruses with three Green Herbs.
Two Green Herbs and a Blue Herb make different combinations in the games. In Outbreak, this creates Anti Virus (L); in File #2 this creates three Anti Viruses.
- George's starter weapon, the Ampule Shooter, can be loaded with Anti Viruses. As ammunition, they deal some 1000HP damage to most enemies. Against Zombies this is 2000HP, while in Showdown 1 and Showdown 3, Thanatos loses 400HP.
- In both games, it will hold the infection for 90 seconds.
- In desperate times, it will suppress the effect of the nerve gas.
