“Initial tests of the override system are promising. Against unsecured or lightly-encrypted targets, the Eyebots have a 98% success rate. More heavily protected systems are still problematic. Military-grade encryption presents a very real possibility of critical overload of key systems.”— Dr. Whitley, Experiment log 369248/A
To complete this quest, the Courier must proceed to the Control Panel from which the missiles may be launched. Should the courier desire to select "Attempt to cancel the launch.", ED-E must be rescued first. If not, the quest fails and leads to The Apocalypse.
In order to rescue ED-E, the courier must free him from his pod in the repair room near the elevator to the temple. ED-E is located in pod number 2 and can be released by using the terminal on the table in front of the pods.
Once ED-E has been rescued and the Courier has dealt with Ulysses, proceed to the launch control pad and select the option for ED-E to hack it. This will initiate a recording from Dr. Whitley. The following dialogue will explain that the eyebots can override heavily encrypted data, but will probably not survive the process.
Everything that ED-E is carrying will be returned to the player's inventory after the quest.
If the Courier has a reputation that does not allow Veronica Santangelo to become a follower, the reputation increase with the Brotherhood of Steel will then allow them to have Veronica as a follower if one chooses to visit her after the conclusion of Lonesome Road.
