The Underground Rats

The Underground Rats is a vanilla slaughter map for Doom II. Released in February 2021, it was designed by Alexis Jeanson (Roofi), as an homage to Hell Revealed II, whilst using, at most, 2000 linedefs. Aside from a custom sky by Brett Harrell (Mechadon), as well as a set of waterfall patches, it exclusively uses stock textures / flats. Finally, it utilises a MIDI piece by Petter Mårtensen (Thyrbse): "The Creeps."

Secrets

 * 1) At the west end, head to the block north of the blue key and use the north wall to find a switch. Use it and quickly run east, past the bridge, then northeast to a megaarmor. (sector 56)
 * 2) At the east side, enter the south U-shaped hall and at the west side, use the east wall that looks different. Take the lift up to get a green armor, a soul sphere, and a switch. (sector 260)
 * 3) Leave the easternmost part of the map and look north and get on the railing below. Follow it to energy cell packs and boxes of rockets. (sector 274)
