Detailed walkthrough
The End is a very simple quest. All you have to do is go over to the missile contol panel after you deal with Ulysses. Then you need to select "Attempt to stop missile launch". Note: you must have rescued ED-E to accomplish this. If not, then this quest fails and leads to The Apocalypse. In order to rescue ED-E, you must free him from his pod in the repair room near the elevator to the temple. He will be in pod number 2 and can be released by using the terminal on the table in front of the pods. Once he is rescued and you have dealt with Ulysses, go over 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 they developed can override encrypted data but will not be able to survive.
