The Underground was located within the grounds of the Spencer Estate's Courtyard, and led to the secret entrance of the Arklay Research Facility. It was reached through a waterfall in the courtyard.


The Underground was visually similar to an old sewer system. It was mined out, with the intention of allowing access to the Research Facility entrance. It featured numerous crank and boulder traps, items and secret rooms.


The Underground featured a number of different enemies:

-Giant Spiders
-The Black Tiger

Enrico's Death

It was in the Underground that S.T.A.R.S Bravo Team leader Enrico Marini was found injured. He informed Chris Redfield that there was a double-crosser within S.T.A.R.S (Albert Wesker). Before announcing who the traitor was, Wesker assassinated Enrico from within the shadows, and ran away before Chris could notice him.
