The narrative of Warzone 2 DMZ is heavily intertwined with the various Faction Missions available for players to complete. Though the conflict between each faction is largely centered on Al Mazrah, the emergence of a strange chemical developed by Konni seems to have some significance with the coming attack at Zaya Observatory. Operators must intervene in the Story Mission: Russian Gas, which will have you investigating this particular chemical.
Russian Gas is the Season 4 and 5 Tier 5 Story Mission for the White Lotus Faction. To complete it, you must infil into the Koschei Complex with the Vondel Gas Sample, find the Koschei Complex Gas Sample in the south of the Defense Research Division, and then validate the chemical similarity between the Vondel Gas Sample and the Koschei Complex Gas Sample at the machine in the External Ops Sector. Fulfilling all three objectives will reward you with Snow Plow operator skin and 40,000 XP.
Infilling Into The Koschei Complex With The Vondel Gas Sample
The very first objective of Russian Gas tasks you with infilling into the Koschei Complex with the Vondel Gas Sample. Those of you that have completed Chemist’s Sources should be familiar with the Vondel Gas Sample, as it is the mission item you had to secure for the final step. If you have not done so already, take this item from the maze just south of the Vondel Fire Department and successfully exfil with it.
From here, infill into Al Mazrah and head to any one of the bunker entrances to head into the complex. While simply infilling into the Koschei Complex with the sample will do the trick, we recommend heading over to the Oasis bunker entrance, which will make completing the second portion of this mission a lot easier.
Finding The Koschei Complex Gas Sample
The second objective of Russian Gas tasks you with finding the Koschei Complex Gas Sample in the south portion of the Defense Research Division. The Defense Research Division can be accessed through the Oasis bunker entrance in Al Mazrah – though we recommend stocking up on Radiation Blockers and Gas Masks before heading here.
Once you have infilled into the complex via the Oasis bunker, you will find yourself within the Defense Research Division. From here, you will need to locate the Koschei Complex Gas Sample. You will find this item within the third radiated room (closest to the Chemical Treatment Plant) within the first chamber to the right of this room’s entrance. Simply looting this item will fulfill the second objective.
Once you have the Koschei Complex Gas Sample, you can either extract with the sample and complete the final portion in a separate deployment, or head on over to the External Ops within the same deployment.
Validating The Chemical Similarity Between Both Samples Using The Machine In The External Ops Sector
To complete the final objective of Russian Gas, you will need to validate the chemical similarity between the Vondel Gas Sample and the Koschei Complex Gas Sample at the machine in the External Ops Sector. The External Ops is the area of the complex that is accessed via the Rohan Oil bunker entrance on Al Mazrah. However, if you are completing this portion within the same deployment as the previous objective, then you will have to access the External Ops via the Chemical Treatment Plant.
Whichever method you choose, head on over to the room towards the very end of the External Ops. Here you will find the machine required to fulfill this objective on the far left-hand side of this area. Heading to this machine will trigger a prompt to appear, and interacting with it (while possessing both gas samples) will complete the third objective.
