Haven's Hollow is heavily inspired by Zombies modeWith recognizable locations like the Shattered Veil Mansion and Liberty Falls itself recreated within the game world, it was only a matter of time before hidden secrets and subtle Easter eggs appeared. Among them, a special challenge stands out: the Blood Moon Ritual Easter Egg. This mission combines exploration, teamwork, and a touch of zombie-style horror.
What is the Haven's Hollow Easter Egg from Blood Moon?
The Blood Moon Easter Egg in Haven's Hollow is a secret mission Scattered across various areas of the map, it culminates in a stunning visual transformation of the sky, with a red-tinted moon surrounded by tentacles. It's not merely an aesthetic detail: upon completion, players receive an exclusive calling card called End or Beginning, a large amount of experience, and a powerful temporary effect on their operator.
This secret is presented as a kind of cooperative mini-questVery much in the vein of classic Zombies missions where you have to activate altars and "feed" soul circles. To complete it, you'll have to gather three ritual objects scattered at very specific points on the map, activate a strange ritual in the Mansion, and then use all of the above in the large blood circle located next to the Barn.
Although it can be attempted alone, the design of the Easter Egg is clearly oriented towards squad playBecause you have to cover a lot of ground, defend specific areas, and hold your own with a special weapon that puts you at a clear disadvantage. If you go with friends, each of you can take charge of a part of the map and the combat, which makes the process much more manageable.
The main reward isn't just the business card or the 10.000 experience pointsBut it also highlights the effect players gain from completing the ritual: their operator is surrounded by a special glow, and all enemies appear outlined, making it much easier to spot rivals for a time. It's a reward that has both a visual and gameplay impact.

First step: gather the three ritual objects in Haven's Hollow
The first part of the Easter Egg consists of locate three specific objects These items function as components of the ritual: a vial of blood, a strange stone of eldritch origin, and some animal bones. Each of these is located at a different point of interest on the map, and it's best to divide the tasks among the team members to avoid wasting time.
Although there is an optional method to view all locations on a projector within the Research CenterIt's not essential to follow it to the letter. Objects can only appear in a limited set of possible positions within their corresponding zone, so once you know those locations, it's simply a matter of quickly checking each point until you find the item you need.
If you want to take things more slowly, you can start at the Research Center, go up to the second floor in the south wing, and pick up a transparency sheet. Then, on the ground floor in the east wing, you'll see a projector where you can place it. Activating it will show you the [information/image/etc.] more visually. general distribution of ritual objects on the map. This helps a lot if it's your first time doing the Easter Egg and you're a bit lost.
Location of the blood vial at the Research Center
The blood vial can only appear inside the medical laboratory Located in the northern part of the Research Center, on the second floor of the building. For quick access, it's best to enter from the top, either through the roof or via the stairs leading to that section.
Inside the laboratory, your objective is to locate the centrifuges.These are cylindrical machines where blood samples are processed. There are three possible centrifuges that can contain the vial, but only one will be open in each game, and that's the one you must find to obtain the item.
- The first centrifuge is right at the entrance to the laboratory. From the north side: look at the first room on the left and check the right side of the room, where you'll see the machine. If the lid is open, approach it and hit it with melee attacks so the vial falls to the floor and you can pick it up.
- The second option for the vial is located further down the laboratory corridor.Continue moving forward from the first centrifuge and examine the area under a cart or wheeled stretcher. The centrifuge will be partially hidden by this cart, and, if it's the correct one, simply tapping it will release the blood vial.
- The third possible location is inside the Executive Officewhich is accessed from the door to the right of the second centrifuge. Once inside the office, you should see another machine on a shelf; again, if it's the one that's open, you'll have to hit it to make the vial fall to the floor and add it to your inventory.
How to find the eldritch stone in the Coal Depot
The second item you need for the ritual is the eldritch stone.A strange fragment hidden in the Coal Depot. Unlike the vial, here you won't be searching directly for the stone, but rather you'll have to interact with several yellow safety helmets placed at very specific points in the area.
At the Coal Depot you will see three yellow helmets placed around the areaSome are upside down and others are upright. The trick to finding the stone is to locate the helmet that's right-side up, because only hitting that one will reveal the object you're looking for.
- One of the helmets usually appears in the upper north corner of the main building. From the Coal Depot. Walk along the highest part of the structure, close to the north wall, and carefully check the ground until you see the helmet placed in the area; check if it is upside down or upside down.
- The second likely hull is located in the eastern partIt's usually next to a pile of coal or similar material. Again, approach the area, locate the helmet, and note its orientation. You don't need to shoot; a simple melee attack will suffice if it's the good helmet.
- The third hull appears to the south of the Coal DepotNear a barrel; it's easy to miss if there's combat in the area, so it's best to clear the area before you start searching. When you identify which of the three helmets is on the right, hit it and the eldritch stone will appear underneath, ready to be collected.
Where are the animal bones in the pond?
The last object needed for the ritual is some animal bonesLocated in the Pond area. Unlike the other two items, this one is always hidden under small wooden structures, so you'll have to crouch down and search.
Around the pond there are three possible structures under which the bones may appear: one near the center of the area, another to the west and the third in the southeast area, under some stairs that lead to a wooden shed.
- In the central part of the pond there is usually a small wooden structure or walkway; position yourself next to it, lie prone, and look beneath the surface to see if the bones are there. If they don't appear in that structure, get up and move on to the next one.
- The second spawn point is to the west of the pond.It's also under a wooden structure near the central area of the water. Again, the quickest way is to drop to the ground, look carefully underneath, and find the interaction icon to pick up the object if it's there.
- The third and final possible location is on the southeast side of the fieldJust below the stairs leading up to a small wooden shed. Position yourself at the bottom of the stairs, lie prone, and carefully examine the area below until you see the bones. Once you locate them in any of these positions, simply interact with them while lying prone.

Second step: activate the ritual symbols in the Mansion
With the three items now in your possession, The next move is to go straight to the Mansion, one of the most recognizable locations on the map due to its connection with Zombies mode. Your objective is in the building's attic or loft, where you'll find two key elements of the ritual: an old gramophone and a rather unsettling mirror.
- The first step involves interacting with the gramophone in the attic To activate it, unsettling music will begin to play, indicating that you have begun preparing the ritual. Once activated, the following actions must be performed quickly to ensure everything falls into place correctly.
- The second thing you need is a Psych grenadeThis grenade causes visual and auditory hallucinations when it explodes near you. It usually appears in the attic itself, or right in the door frames leading to the loft, so you shouldn't have any trouble finding one. Equip the grenade and throw it at yourself to activate the psychedelic effect.
- While under the influence of the Psych grenade, approach the attic mirror. and hold the interact button. At that moment, a brief event will be triggered: after looking at yourself in the mirror while still hallucinating, a sheet of paper will appear next to the gramophone, which formally initiates the main ritual. Be aware that picking it up will trigger a rather strong jumpscare, so don't be startled if you're wearing headphones.
- When you pick up the note, you'll see three red symbols begin to glow in the attic. on different objects: a bloodstain on a surface, an animal skull, and a rock embedded or stuck to the wall. Each of these symbols is associated with one of the three objects you collected earlier: the blood vial, the animal bones, and the eldritch stone.
- It is very important that you memorize or write down the relationship of each object with its symbolThe bloodstain represents the blood vial, the skull corresponds to the animal bones, and the stone in the wall is linked to the eldritch stone. Order and association will be crucial when you reach the Barn and have to place each item on the correct symbol within the ritual circle.
Third step: complete the Blood Circle in the Barn and obtain the Uln'drn sword
With the information from the symbols in mind, It's time to head to the BarnAnother key location in Haven's Hollow is the area you're interested in. It's outside, in the eastern zone near the main structure. Upon arrival, you should clearly see a large blood circle drawn on the ground with a series of symbols scattered around it.
Inside that circle you will see several icons engraved on the groundBut only three of them match the symbols you saw earlier in the Mansion's attic: the bloodstain, the animal skull, and the rock. Your task now is to place each of the ritual objects directly onto its corresponding symbol, respecting the association you observed earlier.
When each team member correctly places their object on the appropriate symbolThe ritual will activate, and an altar will appear in the center of the circle. On that altar, materialized as a melee weapon, you will find the Uln'drn sword, a unique weapon linked to this Easter Egg, similar to others. secret weapons in other gameswhich will be essential to complete the next stage of the challenge.
One of the players must collect the sword Uln'drn from the altar. From that moment on, the wielder will be bound to it, unable to release it until the ritual is complete. Furthermore, the one carrying the sword will be unable to replenish their armor, leaving them at a significant disadvantage against enemies. The sword itself isn't particularly powerful compared to other weapons in the game, so it's best if the rest of the squad handles most of the eliminations.
From that moment on, the blood circle functions as a classic “soul box” Zombies: Each opposing player who dies near the circle will have their soul absorbed into the ritual. Visually, you'll see it as a kind of beam or streak traveling from the enemy's body to the pentagram being drawn in the center of the ritual area.
The goal is to get at least five enemy player kills in the vicinity of the circle for the pentagram to be fully drawn. It's not necessary for only the sword wielder to kill them; any team member can contribute kills as long as they occur within the blood circle. However, it's crucial to protect the one wielding Uln'drn, as they are much more vulnerable since they can't replenish their armor.
When the staff is closed and the circle clearly shows all its linesThe player wielding the sword must then return to the central altar and give it back. This final action completes the Blood Moon ritual, and within seconds the landscape of Haven's Hollow will begin to change dramatically.
Upon completion of the Easter Egg, the sky on the map transformsThe celestial vault is stained with a deep red moon, surrounded by tentacles that reinforce the dark, Lovecraftian atmosphere of the place. In terms of gameplay, all squad members who have successfully participated in the ritual receive the End or Beginning calling card, a total of 10.000 experience points, and a visual effect that makes their character glow and allows them to see enemies outlined, greatly facilitating their location.
This highlighting effect and the shine on your device are not purely cosmetic.While they're active, you'll have a clear tactical advantage by being able to spot rivals in the environment sooner, which is especially useful in a frenetic mode like Resurgence. Furthermore, the Easter Egg adds variety to your matches, transforming a simple competitive round into a kind of cooperative adventure with horror elements.
Knowing this secret and how to complete it point by point allows to get more out of Haven's HollowEspecially if you play in squads and want something different beyond just dropping in, looting, and fighting nonstop. Between the search for items in the Research Facility, the Coal Depot, and the Pond, the strange ritual with Psych grenades in the Mansion, and the final climax of charging the Barn circle with enemy souls, this Easter Egg adds an extra layer of depth and spectacle to Warzone that's worth experiencing at least once.
