The Underground Rats

The Underground Rats is a vanilla slaughter map for Doom II, which was designed by Roofi and released in May 2020. According to him, its design draws inspiration from the maps of Hell Revealed II. Aside from a custom sky by Brett Harrell (Mechadon), as well as a set of animated waterfall textures, it exclusively uses stock textures / flats. Finally, it utilises a MIDI piece by Petter Mårtensen (alias Thyrbse): "The Creeps."
