The g-Virus is a consumable item. One can be obtained from purchasing the Zombie Defense Pack. In addition, one also has a chance to be obtained as a bonus drop from successfully performing a surgery.
When consumed on a player, the g-Virus transforms the player into a zombie. This direct infection ignores the immunity granted by an Antidote or the Zombie Jammer. When another player gets punched by the zombie, the former also becomes a zombie themselves.
When an infected player chats, their message appears in dark green, with "Zombie speak" added on occasion, such as "BRAINS!" or "Brraaiinnss...". The zombie speak originally extended vowels and alternated capitalization randomly, but that was cut so chatting as a zombie would be less annoying to players.
- The item was added as a prize for the winner of an event hosted by the developers in the GROWTECHPHARMA world on May 17, 2013. A player named Viking later won the g-Virus on that day. Before May 18, the item was unusable and had the name "Mysterious Liquid" (instead of g-Virus). The event's storyline suggests that the zombie virus outbreak began with the stolen g-Virus.
- Prior to May 17, the Mysterious Liquid was named "Stop snooping!".
- Consuming a Homeopathic Medicine on a player also has a chance to turn them into a Zombie.
- When a Weather Machine - Apocalypse is placed in a world, a random player would turn into a Zombie every hour, who could be killed with a gun, although Zombie Brain would not be awarded unless the g-Virus pandemic is in progress.
