The Researcher’s Dilemma mission in Call of Duty’s DMZ mode will send players traveling across Vondel to steal some research documents and replace them with a falsified copy. Players will have to first gain access to the Veterinary Office at the Vondel Zoo and find the researcher’s notes before making the sabotage switch and completing this Black Mous faction mission.
Researchers Dilemma Objectives
The Researcher’s Dilemma mission has three main tasks players must complete in a single mission as they fight from the zoo in Vondel to the castle in the Northwest corner. Players will be required to find the research notes located at the zoo, deliver them to a church near the castle, and return with a fake set of notes and plant them in the veterinary office in place of the original document. To complete Researcher’s Dilemma, players will have to complete the following objectives:
Access the Animal Care Room
Before tackling this missionplayers will first need to get their hands on thecorrect unlock key.Players will need akey to the Veterinarian Officeor a Skeleton Keyto get access to the Animal Care Room where the Vondel Gas Research Notes are stored. If players do not have a key in storage to bring into the game with them, there is a good chance of finding the key if players canacquire a supply drop at the zoo. If not, players will have to run deployments completing objectives and contracts until a key is found and exfil and redeploy with the key in hand. There is also a good chance the building the Animal Care Room is in will spawn as a stronghold, so be prepared andequip a stronghold keycardwhen setting a loadout.
Once players have the Veterinary Office or Skeleton key,head to the Zoo at Vondel. The vet’s office is located inthe building in the far Southwest corner of the Zoo, on the first floor.Open the Animal Care Roomwith one of the proper keys andsearch the counters to the left to find the Vondel Gas Research Notesnext to some blue-lidded test tubes.

Finding the False Notes
With the research notes acquired,head to the castle in the top left corner of the map. Players will want tolook for a church located just southof the castle complex.
Climb inside using the boxes to get through the broken window and look for the ladder to the second floor. The second floor will be small, with only one room. In the corner diagonally across from the ladder to the first floor players willfind the False Research Notes.

Place the Vondel Gas Research Noteson the ground by interacting with any of the open areas on the ground of the second floor,pick up the False Research Notes, and prepare for the voyage back to the Vondel Zoo.Deliver the false notes to the veterinary office in the exact location where the research notes were initially acquired. Once players deliver the false notes the mission will complete.
