NUTS

Nuts is a single-level PWAD for Doom II meant for limit removing source ports. It was designed by Bernard De Windt (B.P.R.D) and uses as its music track a MIDI sequence of "Kashmir" by Led Zeppelin. Nuts is a massive slaughter map featuring a deliberately outrageous number of enemies, known for slowing down even the most powerful of computers to a crawl upon release. It was created to test the /idgames archive upload function for the author's contemporary work, Equinox, and is now remembered as a quintessential joke WAD. Two years later, it received two sequels, Nuts 2 and Nuts 3.
