This walkthrough will not only give you the necessary steps to complete the game, but will also include suggestions and notes on things to notice, look at, or try, which perhaps have no effect on the game, but serve to enhance the story and the experience of playing. You may find things you didn't notice before, and you might find insight into some of the deeper layers of Overseer's complex plot.

Whenever you see a conversation path listed in the walkthrough, keep in mind that it is not the required path needed to successfully move on in the game—unless specifically labeled otherwise. The conversation paths listed in this walkthrough are my personal favorites; the ones which I feel are the funniest, most appropriate, or most "Tex-an." You can certainly use other conversation paths if you choose, but watch for the paths that are required.

The "Days" used to divide this walkthrough are taken from The Official Tex Murphy: Overseer Strategy Guide, by Rick Barba. This walkthrough originally written in 1998 by James LeMosy.
