- After the Free Update patch, this item becomes a free default item in all player's inventories.
When using this set, as a human, the player can hold one more additional HE Grenade to engage zombies.
As a zombie, the player can throw a Zombie Grenade which inflicts knockback to both humans and zombies depending on the direction thrown. It interrupts the human's aim and enables zombies to reach difficult areas using the knockback power from the Zombie Grenade. In Zombie: The Hero, the knockback effect of the Zombie Grenade is increased.
