Epsilon Bunker

The Epsilon Bunker is an old N.O.V.A. military base "not used since rebellion times" until the Xeno threat to humanity. It's located on New Ceres, and contains a fully functional nuclear warhead. Its inhabitants at the time of Kal Wardin's visit in the first game include Bonesy and Clydesdale, General Korolev and Bravo Squad.
