Orion Moreno's house is an unmarked location in the Mojave Wasteland. Located just north of the NCR Sharecropper Farms.
It is an unremarkable ranch style home surrounded by a broken down white picket fence, and has a fireplace, car port and two entrance doors.
Inside, the bed can be slept in without penalty, however most items inside are considered owned and will result in karma lose if stolen. The interior is also identical to Doc Mitchell's House.
Orion Moreno can be found here unless the quest For Auld Lang Syne has been completed.
Orion Moreno's house only appears in Fallout: New Vegas.
