Main Computer Room + Vengeance

I was curious about an official ruling on the Main Computer Room when used in a V5 game.  Does each villain get to play a card or just the first villain?

Anything that says a/the Villain Deck is hero choice.

(goes off to find source)

EDIT: (Finds source)

Source is the Vengeance rulebook! Under "Additional Rules" on page 7

I believe it says THE villain deck... hence the uncertainty of playing 4 cards (ick!) or just one.  We ended up playing one from the first position villain as it added a  bit of randomness and was not overwhelmingly horrible like playing 4 villain cards would have been.

Cool... glad I played it right.... I could not find the rule on a quick web search as we were playing.
