Zombie Blood

Zombie Blood is a power-up that appears in Origins. It causes the player to be masked in a red fog and disguised as a zombie acting in a similar way to one of the abilities granted by Vulture Aid, as well as slightly increasing the field of view. The Power-Up itself looks like the icon for the Achievement Acid Drip in Mob of the Dead. The power-up lasts for 30 seconds, and can only be used by the player who picks it up.
