MAP09: Even Simpler is the ninth map of Doom 64 and contains some of the eeriest and most frightening BGM. It is the first level to take place in Hell, and as such the sky changes from a starry, space sky to a burning red sky with ominous clouds. It is a homage to MAP07: Dead Simple from Doom II. It is also the first map to feature the mancubus (encounterable from the player in the MAP29: Outpost Omega later...).
