With the release of the new Black Ops 6 Zombies map, Citadelle des Morts, players can discover several secrets, including the intriguing Bartender Easter egg. Completing this will reward you with the PhD Flopper Perk-a-Cola for free. PhD Flopper is a valuable perk, as it grants immunity to self-inflicted damage. This is especially important if you prefer using the Sally & Forth weapon, which fires explosive shots.

Without this perk, firing near yourself can cause significant harm, making PhD Flopper essential for such playstyles.

Guide to completing the Bartender Easter egg in Black Ops 6 Zombies Citadelle des Morts

To complete the Bartender Easter egg in Black Ops 6 Zombies: Citadelle des Morts, you need to collect three different liquor bottles and serve drinks to the zombies. Once completed, you'll receive the PhD Flopper perk as a reward.

Here’s a step-by-step guide:

• Enter the Castle: Fire the cannon to break the main door. Follow the markers that will guide you inside.
• Choose any of the two doors: Once inside, you’ll encounter two locked doors. If you choose the left one, you’ll enter the Sitting Rooms; if you choose the right door, you’ll enter the Dining Hall. Both will eventually lead to the same progression, so feel free to pick either. For convenience, start by opening the right door to enter the Dining Hall.
• Collect the first bottle: In the Dining Hall, go to the east side, where you’ll find a red couch. To the right of the couch is a table, and beneath it, a blue liquor bottle. Collect it.

• Return to the Courtyard: Head back to the Courtyard and take the left door to the Sitting Rooms. In the south section, next to the sitting couch, you’ll find a metal storage shelf with a red liquor bottle on the bottom shelf. Collect it.

• Find the third bottle: Open the locked door next to the Stamin-Up Perk-a-Cola machine, and go downstairs to the Undercroft area. There, you will find another red couch and right beside it, you’ll notice a table with several green bottles. One of them will look different despite being green; collect it.

• Proceed to the Bar area: Go back to the spawn area and head to the bar on the west side. Inside, on the ground floor, the bottles you collected will be on the counter shelf. Stand in the northwest corner of the counter and look southeast. Press the interact button to trigger the serving puzzle.

• Serve Drinks: The counter will show four serving areas, with one glowing in either green, blue, or red. Select the matching color of the bottle you have collected, press interact to pick up a glass, and then face the correct serving area to serve the drink. If you serve a drink in the wrong spot, it will destroy itself but don’t worry — just avoid repeating the mistake, as it may even fail the Easter egg.

You must serve 25 drinks, earning 100 Essence for each. After completing the puzzle, you’ll receive the PhD Flopper perk and collect 2500 Essence in total.
