So i was trying to get the conduit chest and realized i needed to destroy the watchers in the room well. no one could help me at the time so i improvised. after man attempts i was able to solo the watchers and get the chest. How i did this was with the use of a rocket launcher a Titan and the use of the rally barricade. Then you must find the perfect spot that has the best line of sight of all 4 watchers. Lastly and the most tricky part of them all is getting the timing of killing the all off. its Ideal that you start destroying them from left to right or left to right. To me it seems from when you first kill the first watcher you'll have a total of 6 seconds (for what i noticed) Until the watchers go off and summon the Cabal. After i actually got it down and got all the watchers by my self i wondered if it is possible to solo other rooms with watchers in them. But i will need to test them first. If anyone would like to see how i did it message me on Xbox live and i can share the clip with you. My GT is TheMrDarkrider.
