It is a small shack containing a computer terminal and empty protectron pod, scientific equipment, and a few metal boxes. Accessing the terminal provides some background information on Lesko's experiments and a map-marker.
- Doctor Lesko's password recording - Found on the desk.
- If one did not loot items before the completion of Those!, the ownership will revert to Doctor Lesko and anything looted afterward will be considered theft.
- Dr. Lesko's password recording is Formicidae, which is the familial classification of ants.
- Going into Lesko's shack is considered trespassing, therefore, if one stays too long, Lesko will flee.
The recently built shack appears only in Fallout 3.
It is possible to become trapped in this shack, unable to move. [verified]
