The G-Virus is an item distributed through the Zombie Defense Pack, as well as obtainable from surgery. It is un spliceable and if a player gets punched by a zombie with the zombie virus the player becomes a zombie. Direct infections with the G-Virus ignore the immunity granted by an Antidote and Zombie Jammer.
The item was added one day before the update as a prize for the winner of the GROWTECHPHARMA course. The winner of the early virus was Viking, though the G-Virus was unusable at the time, and was labeled "Mysterious Liquid." The GrowTech Pharma storyline suggests that the zombie virus began with the stolen virus.
- When an infected Growtopian chats, their message appears in 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. They also only speak in a dark green colour.
- A Zombie Jammer could be placed in a world to prevent any player from infecting other players. Another method commonly used by other player (that could not afford a Zombie Jammer) will use a set-up call Zombie test. The reason why this set up works because a zombie cannot jump as high as normal players. It can be used in a World Locked world or not.
- Zombies are the main antagonist in the Zombie Pandemic event in which Z-Jammers won't work and you can get zombie brains.
