|The following is based on developer test content cut from Fallout: New Vegas and has not been confirmed by canon sources.|
An empty metal room, with nothing in it, not even lights. There are five other identical rooms which must be noclipped into to access, and one larger, equally empty room. This cell shares its layout with OVSleepCell01.
OVSleepCell02 appears in the game files of Fallout: New Vegas but should not be considered canon because it is a test cell.
