The basement appears to be a large firing range. The Courier stands behind a barrier on a viewing platform while two Securitrons stand below in said firing range. There are no entrances or exits accessible by the player, and the area can only be visited once during a mission.
The terminal that can be seen across the room that can't be accessed simply has a status message for the Lucky 38's main reactor. At the time of watching the Securitron's demonstration, it was stated that the reactor was offline. If the player turns the reactor on by completing Wild Card: Finishing Touches or The House Always Wins VII, the terminal will be blank.
If the energy barrier/wall is hit with a power fist, bloodspatters will come off.
The special power of the sonic emitter does not affect the energy barrier.
