The Watchers
Location: Eos
A huntquest. In this case, hunt the explosive listening devices in Kett camps on Eos.
Like the canisters in Volatile, these need to be shot, rather than scanned. You can narrow your search area a bit in that they only seem to appear in the Kett installations available after the radiation has cleared. Find three to reveal a navpoint in the far northwest.
Clear out this base- ….and that's probably it, because this quest is bugged. SAM may or may not repeat 'Standby' from time to time, but this error is present whether or not you've visited the final base prior to it being a mission objective. You'll just have to let the Kett-slaughter be its own reward.
