The House Always Wins, VII

The House Always Wins, VII

You still need to boost the Lucky 38's transmission signal to allow  for control of the Securitrons at Hoover Dam.

You've been given an Override Chip which you can use to extend the transmission signal of the Lucky 38 Casino.  Travel to the El Dorado Substation or somewhere closeby, and enter the garage. There are a few ways in which you can do this:

• Equip an NCR Uniform and enter with ease.  If you don't have an NCR Armor you can attempt to lure one of the NCR troops towards you (preferably one of the troops that comes running towards you when you first walk up to the garage).  You can then stealthly kill him/her (which works best if they're far away from their mates, if you use a Stealth Boy and a silenced weapon aiming for their head, finishing them off in VATS.
• Kill the NCR troops.
• Sneak in (with a Stealth Boy) without being seen.

Inside the garage, locate the terminal and use the Override Chip.  Return to Mr. House and inform him of the good news.  This also starts part VIII of this quest, which is shortlived - you only need to accept your final mission and it will conclude.  Do realize that accepting this mission will inevitably finish the game; there is no turning back from here.
