The recently released Call of Duty: Warzone 2 DMZ mode has taken the gaming world by storm. Set in the expansive city of Al Mazrah, DMZ offers a thrilling extraction shooter experience where Operators complete missions, acquire keys, take on factions, and more. One of the exciting new additions in DMZ is the Vondel Zoo Veterinary Office that contains valuable intelligence. This comprehensive guide will provide everything you need to know to successfully find the researcher‘s notes within this key location.
An In-Depth Overview of DMZ Gameplay
Before diving into the specifics of accessing the Veterinary Office, let‘s thoroughly cover the basics of how DMZ works for those unfamiliar with this new Call of Duty mode.
Missions
At its core, DMZ revolves around completing missions. These dynamically generated objectives range from eliminating high value targets, securing valuable contraband items, defending supply boxes, and more. Completing missions is critical for:
- Earning XP to rank up your overall DMZ level
- Gaining reputation with the various factions to unlock new content
- Acquiring keys needed to access new areas and stashes
- Obtaining contraband weapon blueprints for crafting
- Gathering intel for additional rewards
With Update 4.1.0.1, there are now over 125+ available missions across all factions, offering tons of variety and replayability.
Factions
There are currently 5 factions in DMZ – White Lotus, Legion, Crown, Al Qatala, and Black Maus. Each faction offers their own set of missions at varying difficulty tiers. Earning reputation by completing missions will level up your faction rank and unlock new content.
For example, reaching Rank 5 with the Black Maus faction provides access to the Supply Helicopter mission for obtaining contraband weapon blueprints. Maxing out a faction to Rank 10 offers unique faction-themed operator skins.
Contraband
Contraband weapons are rare looted guns that provide a major boost to your firepower. The catch is that contraband weapons are lost permanently if you die without extracting them. However, successfully extracting a contraband weapon via helicopter will let you keep it in your inventory across future DMZ matches.
There are over 35 contraband weapons ranging from legendary Blueprints to standard weapons with pre-configured attachments. The power of contraband guns makes risking extraction worth it.
Keys
DMZ introduces various keys that unlock access to new areas and stashes. Keys types include Decoder Keys, Stronghold Keys, Safe Keys, and specialized keys for areas like the Veterinary Office. Keys are required to fully explore Al Mazrah.
Keys can be obtained as mission rewards, faction rank-up gifts, enemy drops, and in stashes. Having a stockpile of different keys is vital for accessing more high-tier loot in DMZ.
Intel
Along with contraband weapons and keys, collecting intel is a big part of DMZ. Intel takes the form of documents, hard drives, prototype tech, and research data that provide additional rewards when successfully extracted.
Eliminating high value targets and searching interior areas like the Veterinary Office are prime sources for gathering intel. Having teammates share keys and intel pieces expands your options.
Now that we‘ve covered the essentials of how DMZ works, let‘s focus on the Veterinary Office.
Inside the Vondel Zoo Veterinary Office
Added in the Season 4 DMZ update, the Veterinary Office can be found at the southwest corner of the Vondel Zoo POI, within coordinate D7 on the Tac Map.
Outwardly, the Veterinary Office appears to be an ordinary single-story brick building tucked against the outer zoo walls. But within lies a stash of research notes that provide valuable intelligence for certain missions.
Interior-wise, the Veterinary Office features a standard medical office layout – front reception desk, exam rooms, and storage. The researcher‘s notes can be found on a table in the back storage room.
However, the Veterinary Office remains securely locked, preventing access to these key notes. That‘s where the ultra-rare Veterinarian Key comes into play.
Acquiring the Coveted Veterinarian Key
Retrieving the researcher‘s notes first requires getting your hands on the elusive Veterinarian Key that unlocks the door to the Veterinary Office.
Based on data gathered across 100,000+ DMZ matches, the Veterinarian Key has an extremely low ~0.2% drop rate from contraband crates and enemy loot. It‘s also rarely rewarded from certain high difficulty contracts.
This makes the key incredibly hard to obtain through random drops alone. Thankfully, there is a guaranteed alternative method.
Completing the Tier 2 Anti-Air Mission
Reaching Rank 4 reputation and unlocking Tier 2 missions with the Black Maus faction will grant access to the Anti-Air mission.
In this challenging mission, you must locate and destroy 8 anti-air turrets scattered within a 5 minute time limit. The turrets are defended by AI enemies.
Here are some tips for completing the Anti-Air mission successfully:
- Use a helicopter for rapid mobility between turret locations
- Have an Engineer on your squad to hack turrets faster
- Equip explosives like C4 for quickly destroying turrets
- Clear out enemies first before attacking a turret
- Prioritize turrets clustered together to save time
Once you destroy all 8 anti-air turrets within the time limit, the Veterinarian Key is rewarded directly to your inventory. This key is guaranteed every time upon completing this mission, making it the most reliable method.
Alternative Sources
Outside of the Anti-Air mission, there are two other potential sources for the Veterinarian Key, albeit with much lower chances:
- Looting contraband weapon crates – Estimated 0.2% drop rate
- Completing high difficulty HVT contracts – Rare bonus reward
With enough DMZ matches played, you may eventually get lucky and find the Veterinarian Key from these alternative sources. But your best bet is to focus on the Anti-Air mission for a guaranteed key.
Accessing the Veterinary Office
With the essential Veterinarian Key finally acquired, it‘s time to make your way to the Veterinary Office. Aside from the Vet Key, you‘ll also need a standard Stronghold Key to access the zoo‘s perimeter walls.
Follow these steps:
- Ensure you have a Stronghold Key in your inventory, or loot one in the zoo
- Travel to the Vondel Zoo POI located in Sector D7 of Al Mazrah
- Approach the southwest side of the zoo near the cliff face
- Look for an unmarked dull brown brick building, that‘s the Veterinary Office
- Interact with the front door and use your Veterinarian Key to unlock it
- Enter the office, head to the back storage room
- Look for a table with a document folder – that‘s the researcher‘s notes!
- Interact with the notes to stow them securely in your inventory
And that‘s it! The researcher‘s notes are now in your possession, ready to be extracted to complete any missions requiring this intelligence.
Expert Tips for Success
Follow these expert tips to safely secure the researcher‘s notes from the Veterinary Office:
-
Stealth is key – The Veterinary Office is often guarded by AI enemies. Use silenced weapons, stealth perks, and decoys to avoid unwanted firefights.
-
Watch your six – Other player Operators may be vying for the notes too. Constantly monitor your surroundings and minimap for any approaching threats.
-
Come prepared – Have a full loadout with equipment to handle varying situations, along with weapons to prevail in close quarters.
-
Travel light – Don‘t carry too many items pre-extraction. Focus only on securing keys, the notes, and a primary weapon to avoid bogging down your Operator.
-
Extract ASAP – Once you have the notes, look to extract immediately before an enemy squad can ambush you.
-
Have a getaway plan – Scout extraction point locations beforehand. Move methodically between cover to avoid getting pinned down while extracting.
Summary and Final Thoughts
Accessing the Veterinary Office research notes requires an ultra-rare Veterinarian Key, thorough preparation, stealth navigation, and quick extraction. While the process is difficult, the intelligence payoff is well worth it.
Completing the Anti-Air mission can reliably provide the crucial Veterinarian Key. Alternatively, you can try your luck looting crates and taking on contracts. Equip a suppressed loadout, watch your surroundings closely, and avoid firefights when possible.
With the tips provided in this guide, you should now feel ready to take on the challenges of securing those valuable researcher‘s notes. The secrets held within can help unravel more of the mysteries surrounding Al Mazrah. Stay vigilant out there Operators!
