The House Always Wins VII

The House Always Wins VII is a main quest in the Fallout: New Vegas.

Quick walkthrough
The player must install the override module at the El Dorado substation. Several NCR troopers guard the substation and warn the player that there will be trouble if they enter. Alternatively, wearing NCR armor can cause the guards to refrain from shooting on sight.

After accessing the terminal, the player will gain Infamy with the NCR. Upon completion, return to Mr. House.

Detailed walkthrough
The player starts by talking to Mr. House, after completing The House Always Wins VI. He will explain, and the quest begins.

Once you arrive at the substation an NCR trooper will approach you, telling you to keep out. Ignore this and enter the garage door. Wearing NCR armor means they will not open fire.

Once inside, head for the right-hand side of the building, access the terminal and insert the chip. Exit the substation, and report back to Mr. House.
