I noticed that the Securitrons on the Strip street, Lucky 38, and outside the gate in Freeside weren't allies with each other. This mod fixes that. Furthermore it also tweaks Wild Card: Change in Management to set VFSGateGuardFaction and VStreetSecuritronFaction as allies to the PlayerFaction. Lucky38Faction is already set as ally in the vanilla game. It also removes VNCRStreetFaction as a friend to VStreetSecuritronFaction and marks it as neutral. I couldn't find any other way for the Street Securitrons to aid you if you choose to attack the NCR on the Strip. 

There are 2 different versions of this mod. DO NOT USE TOGETHER!

Yes Man and Mr. House - Makes the Securitrons allies after completing Wild Card: Change in Management for the Yes Man quest line and makes the Securitrons allies after completing The House Always Wins I for the Mr. House quest line.

Securitron Allies - Makes the Securitrons allies from the beginning of the game.

Both plugins also make the Enclave Remnants and Securitrons at Hoover Dam friends with each other to make sure they don't fight.

Recommended mods:

House Companion - Adds a Securitron with Mr. House's face and dialogue.

Yes Man Follower - Adds a Yes Man companion to the game.

Yukichiagai Unofficial Patch - Fixes hundreds of bugs with the game including issues with the Securitrons.
