Assault on Moonbase Cresta

Assault on Moonbase Cresta is a 1-level Doom II PWAD released on 5 March, 1999 by Sam Ketner. Set on a lunar base overtaken by Hellspawn, Assault on Moonbase Cresta utilizes many Boom engine features, as well as several custom graphics, to create a realistic environment, and could be considered an immediate predecessor for the author's Assault on Tei Tenga released later that year for ZDoom.
