Eliminate the Revelator.
- Getting to the second blockade, you will hear a truck horn from a distance down the road to the East.
- The Revelator is barreling down on your location.
- If you have Proximity Explosives, go to the East.
- Lay them down in the middle of the road.
- 3-4 explosives will be enough to destroy the Revelator easily.
- Go to the truck with the turret on the back after that.
- Just wait for the Revelator to come driving in, hit the explosives and explode.
