Wild Card: You and What Army?

 is a quest in Fallout: New Vegas. Yes Man sends the Courier to The Fort to activate an army of dormant Securitrons.

Objectives

 * (Optional) Find Mr. House's hidden bunker, buried beneath the Legion stronghold at Fortification Hill

Walkthrough
is started by talking to Yes Man in the rear of Benny's presidential suite on the 13th Floor of the Tops Casino.

The bunker is inside the weather station at the Fort. To gain access, either:
 * Have Caesar give you a quest to find the bunker and destroy it, if you come to meet him after killing Mr. House and installing the Mk. 2 securitron program. If you accept, he will let you enter, at which point you can either destroy the army or activate it; Caesar will assume that the rumbling of the Army activating was whatever you used to destroy it.
 * Kill Caesar to remove the Platinum chip from his body

Inside the Securition Vault there is a constant +1 RAD.

Option: Upgrade Securitrons
Traversing the vault can be made easier by using the terminal in the Security room to deactivate the turrets (repair 50) and protectrons (science 75) guarding it. Traverse the vault and enter the door labeled "Systems." Insert the Platinum Chip into the Securitron Operations Console.

Option: Disable reactor
Otherwise, simply fire one round into each of the 3 reactor modules.

Bugs

 * Caesar can glitch when you talk to him. He will tell you that he wants you to do something but the only option was "I'm done working for you".


 * If you progress too far in the storyline and do not visit the vault to upgrade the securitrons when you are first asked, a bug may prevent you from opening the inner vault door even though the platinum chip is in your inventory. Killing Caeser doesn't fix this.
