The Empty Perk Bottle is a Power-Up featured in the zombies maps Origins and Zetsubou No Shima. In Origins, if the player has acquired the Golden Shovel and is in Zombie Blood, a dig spot will be glowing red somewhere on the map. These red dig spots will not change spots until they are dug up, and they are randomized each game. If these are dug up, an Empty Perk Bottle will appear which the player can pick up. When it is picked up, a new red dig spot will appear again randomly on the map at the start of the next round. Note that these dig spots are separate from the regular ones, and aren't located at the exact same locations, though they are typically found near each other.
For every Empty Perk Bottle dug up by the player, an extra perk slot will be given, up to 8. They may then buy an extra perk from the Der Wunderfizz machine or a Perk-a-Cola Machine. Going down and losing the perks does not remove the empty slots, as the player can simply rebuy all of their perks.
Using the Staff of Ice to spawn a Zombie Blood is a viable tactic to getting the Empty Perk Bottles quickly without having to depend on random power-up drops as much. It can be used to scout if the dig spot is near the Excavation Site or No Man's Land.
In Zetsubou No Shima, the Empty Perk Bottle can be obtained by completing the top most trial on the pillars in the Ruins of the Ancients or opening up a purple plant with yellow spots on it, though this is very rare.
There are sixteen glowing dig spots around the map. The locations are:
- Between Generators 1 and 2, just outside the laboratories.
- Between Generators 1 and 2, next to the Remington 870 MCS wallbuy.
