Usefulness
This page was created from a link on Underground town which label is "2nd shortest" in the point for before quest I Spy is completed, so there are shorter routes to get to Underground town from vanilla.

Cleanup Crew
In Dead Man's Pass, after navigating through Seargant McMillan dialogue, the quest Cleanup Crew will be offered which goal is "Hunt down and kill Blaze." accepting it, he'll hand you Dead Man's Pass Key, which unlock the door to Underground Ghost Town, where the target is located.

Refusing
By refusing Cleanup Crew, the door Dead Man's Pass Key is for, from Underground Ghost Town has a very hard unlock, and from Dead Man's Pass has either an average locked terminal or a very hard unlock.
