The location of the kett surveillance devices are randomized and presently, may show up at any kett camp.
While exploring camps, SAM will notify Ryder of a surveillance device when Ryder is within close proximity of one. Once one is found, they need a few shots to be detonated. Ryder needs to destroy four devices before SAM can put together a nav-point to the central location of the devices.
Once the nav-point is set and reached, the kett need to be cleared before access to the console will be available. SAM will suggest the data be scrambled so it cannot leave Eos, during this time one wave of kett will be deployed to Ryder's location. And once SAM finishes the scramble, the console will be available to be destroyed.
Once destroyed, the task will auto-complete.
