Render Unto Caesar

 is a quest in Fallout: New Vegas.

Quick walkthrough
Travel to Cottonwood Cove and take the barge to the fort where you will talk to Caesar he will tell you to take the platinum chip and go into the weather station and destroy everything once done return to Caesar

Behind the Scenes
The name of this mission is a reference to a Bible story in which, when shown a coin, Jesus Christ says to "render unto Caesar what is Caesar's and render unto the Lord what is the Lord's."

Bugs
Caesar's Legion may still be hostile towards the player, even when carrying the Mark of Caesar. While wearing Legion armor if you get too close to them in the inner camp they may become hostile.(try a stealth boy to bypass this while sneaking).

The above mentioned bug doesn't happen if you go straight to Caesar after his spy approaches you. It only happened to me when I spoke to Mr. House first.
