Obtain: BĂ©ni-oui-oui in Benny's room
Related Quest: "Render to Caesar" and "House is Always Right, 2"
When you speak with Béni-oui-oui in Benny's room, he will give you three quests including this one (Image 1). Although totally optional, this quest for Béni-oui-oui is relatively important since it will allow you (or not) to take advantage of a larger army of robots. To carry it out, it is a good idea to take advantage of the “Render to Caesar” quest (given by Vulpes Inculta after Benny's death) in order to infiltrate Caesar's fort without incident. So go to Cottonwood Cove and ask Cursor Lucullus to take you to the fort (Image 2). There, hand over your weapons to the gate guard (Picture 3) then head to the top of the camp.

Look for Caesar's tent (Image 4) then leave your companions outside before entering to talk to the master of the place (Image 5). Pretend to accept his proposal then go to the weather station located at the end of the fort. Inside, collect your weapons from the guard at the entrance and then use the platinum token to open access to the bunker (Picture 6).

Fight your way through the bunker to the control console and then use the platinum token to upgrade the fort's Securitrons (Picture 7). You can then go out and report to Caesar so that he lets you go (Picture 8). The quest ends and BĂ©ni-oui-oui is very happy to have new toys on hand (Picture 9).
