Plutonium

new to modding, how do i install this?

this feels like an episode that could be aired during 2012

Same question here. Have you found any solution yet?

Go to your steam library, then go to the game in your library but don't start it. Click on the options and select the game properties (I forgot what it's called) and look around the properties. There should be an option called "Verify integrity of game files" or something.
