A New Threat

A New Threat is a quest and achievement/trophy in the Fallout 4 add-on Automatron.

Detailed walkthrough
The quest is activated immediately after completing Mechanical Menace. The Sole Survivor is told by Ada that they need to go to the General Atomics factory. Once there, they have to fight their way through the factory. At the far end of the factory, the player will find a Quantum robobrain. Killing and looting it will give the player the Mechanist device. The Sole Survivor then gives it to Ada who says it is a satellite tracking device. Ada tell them to install it in her so they can use it to their advantage. To do this, the player has to place Ada in a robot workbench which they must build in one of their settlements. Once it is installed on Ada, she will say that in order to utilise it, they have to kill another Robobrain somewhere in the Commonwealth that is using the same signal. Ada tells the Sole Survivor she needs them to bring her two additional beacons to decrypt the encryption on the signal. When she says this, she places the locations of the Robobrains onto the player's map and the quest ends.

Bugs

 * Searching the robobrain and obtaining the Mechanist device doesn't complete the "Search the Robobrain" objective. You can move forward with the console command.
 * If the player has built the Robot workbench prior to obtaining the prompt from Ada, the quest will not proceed until the current workbench is scrapped or stored, then rebuilt or placed again. Ada may be modified in other ways, but until the workbench replacement occurs, there will be no option to install the Special Mod that is the Radar Beacon.
 * Attaching the radar beacon to Ada may not complete the quest.
