Detailed walkthrough
This quest is triggered by entering Ulysses' Temple for the first time during the quest The Divide. Follow the short path to a terminal. It can open the door to the main hallway, which leads to Ulysses, and also to the maintenance bot room, which contains ED-E. Rescue ED-E for the optional part of this quest. Then follow the main hallway to an elevator down to Ulysses Temple. You now have to "Deal with Ulysses".

If you decide to fight him, be aware that Ulysses has a high health level and is capable of using Stealth Boys, as well as flash-bangs. Ulysses' eyebots are also capable of healing his injuries and providing fire support. One way to take care of the eyebots is to hack the eyebot terminals on the right-side lower level near the missile.

If you decide to spare his life, you have to pass a high Speech check of 100, which causes Ulysses to join the player against the marked men. If you have ED-E in your party (i.e. you have rescued him) and he has played all of his log recordings, or if you have obtained all of Ulysses' holotapes, you do not need to pass the Speech check. Be aware, however, that if you wish to spare Ulysses, any dialogue that suggests deception on the part of the Courier, or attempting to use the holotapes option without having collected all six, will result in Ulysses being disgusted with the Courier. The only remaining option will then be to fight him to the death.

Marked men will show up after the battle begins, or after convincing Ulysses to fight beside you. Once the marked men are dealt with, you may either attempt to stop the warheads, or launch them yourself. This ends the quest and will trigger The End or The Apocalypse, depending on what you chose.

Bugs

 * If Ulysses is killed before all the marked men are killed, the quest will appear stuck. Killing all the marked men will cause the quest to complete and the next quest to start.
