In the "Chernobog" prep mission for the Doomsday Heist Act 3 your goal is to acquire a Chernobog missile launcher from a heavily guarded Merryweather Camp.
In this mission, you need to go to a Merryweather Camp and steal a Chernobog missle launcher. It will be heavily guarded, so it's best if you go there in an Armored Kumara to clear the camp with full protection. You can also take a Buzzard or an Oppressor Mark II to clear them out. Once you've killed all the guards, the driver will get out of the Chernobog and run away. You can then hop into the Chernobog and bring it back to the facility.
On your way back, these mercenaries will keep on coming after you. If they are in front of you and you have enough speed then you can ram into them, which will instantly explode their vehicle. If they are behind you and shooting at you, then don't worry about it as the Chernobog has quite a lot of health and it won't get destroyed. Stay calm and drive it back to the facility.
Successfully delivering the Chernobog to your facility concludes this prep. You are now better prepared for the Escort ULP setup mission. For an overview of all missions, visit the main Act 3 Hub page.
