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. 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.

Trivia

 * A player can obtain a free Zombie Blood, by shooting three flaming carts around the Excavation Site with the Staff of Ice. It will appear next to some scaffolding by the Pack-a-Punch Machine.
 * Another free Zombie Blood is always given as a reward in the Rituals of the Ancients box near Generator 1 after it is first turned on, except on solo, when it is replaced with a Double Points.
 * When in Zombie Blood mode, a voice will call to the player, giving them hints for obtaining staff parts when near specific objects.  For instance, it tells the player to "scratch the surface. Reveal the shards of the Ice Staff" when near a dig site that would reveal an ice staff piece when dug up with the shovel during a snowing round.  Or "the Giants hold many secrets" when in a giant mech footprint while one is approacing, hinting at the wind staff pieces that are hidden in the heads. Also, it tells the player that "the steel warrior must be destroyed" when near the Panzer Soldat hinting towards the fire staff piece.  It is unkown if there are lightning staff hints if a player gets on or activates the tank while under the effects of Zombie Blood.
 * When doing steps for the Easter Egg Little Lost Girl, the aformentioned voice will mention steps depending on how much progress has been made on the easter egg. These steps are also the same steps that Viktor Reznov listed for Escaping Vorkuta. For instance, once all four normal staffs have been crafted, the voice will say "Step One: Retrieve the Key". After upgrading all the staffs, the voice will list off, "Step Two: ascend from darkness"
 * After obtaining the golden shovel and in Zombie blood, a player can obtain free perks by digging a pile of red skulls that spawn once the powerup is received and disappears when its time runs out. If the player already has four perks, a fifth slot will be added and the player can purchase from a Wunderfizz Orb perk station.  Players can repeat this step to gain up to 8 perks.
