Detailed walkthrough
Once you have launched the rocket from the Ashton Silo Control Station, you can travel through the Ashton Missile Silo. Enter the control station and activate the elevetor. Be prepared for a rough ride, as once the elevator has been activated, tunnelers will climb into it and attack you. Once you have reached the bottom of the elevator shaft, continue into the missile silo, and make your way through it to get to the central room. Then climb down into the pit at the bottom. Go through the opening, killing or avoiding the small number of Tunnelers to get to Sunstone Tower.

Climb up the staircases of the tower to get to its roof, being wary of the tunnelers which inhabit the building. Having reached the roof and conversed with Ulysses, you must then climb down the building using the fallen platforms.

Once you get to the platform, follow your map marker through the array of ruined buildings, dispatching any marked men you meet. You will need to detonate a few warheads to pass, and there are a few optional warheads as well.

Once you reach the Cave of the Abaddon, everything will go quite dark. Travel through the cave, killing all the tunnelers, or just run straight through. Enter the door, and you will emerge in the Boxwood Hotel. Climb up the railings and through the two rooms to get to its roof.

Once you emerge, you will talk to Ulysses again, and he will override ED-E, and you will lose him as a companion. Then you must use some railings to climb down from the roof, and travel towards Ulysses' Temple. Use extreme caution when travelling here, as a number of deathclaws patrol the area. Some marked men will be patrolling a collapsed building near a warhead, which you must detonate to continue.

Travel under the collapsed building, and take out any marked men snipers who engage you. Take care when walking around here, as Blade, a marked man, hides here using a stealth boy, and can easily sneak up on you. When the area is safe, travel through the Wastewater Treatment Plant to get to the roof of a collapsed building, being wary of marked men. Cross the top of the building and follow the stairs and walkways, then cross a bridge to get to the second floor of another collapsed building. Travel through the building to get to a marked men camp, and through the mass of mutilated body parts you will find Ulysses' Temple. Enter the large door to complete the quest.

Glitches
If you leave ED-E inside Boxwood Hotel then exit to where Ulysses speaks to you, ED-E will just hover infront of you, and since you can't move your only option is to load a previous save.
